Core Knowledge social studies: Fifth Grade - part 1

 Core Knowledge - Fifth Grade social studies - part 1

As the grade levels go up, the amount of material to review also obviously goes up. Therefore, I am splitting the review into parts, focusing on one unit per part. I only reviewed the units that involve Native peoples, though I may do a short review of the other units as well. 

Unit 2: Maya, Aztec, and Inca Civilizations

Student reader: Chapter 1 is about the Maya and starts with the mythology of the “vanishing civilization” and calling it a mystery. This only serves to perpetuate stereotypes and is a completely inaccurate telling of history. There is no mystery, there was no “vanishing.” The curriculum claims that most of their culture “disappeared,” that they mysteriously “abandoned” their cities, and “mysteriously” transformed. It says it sounds like a “science fiction” movie. This is not only false but harmful to education about Native cultures and civilizations. It also claims they only thrived until 900 CE and every mention of dates simply claims it ended in 900 CE. This is false. It also calls the Maya “one of the first great civilizations of the Americas.” This completely ignores thousands of years of history and peoples. The Maya are not one of the first, they’re just one of the most well known.

The Maya simply reorganized politically and culturally. We can call these time periods the Classic period up from 200 CE to around 900 CE and the Post-Classic period from 900 CE up until Spanish invasion. The civilization simply hit its peak around 900 CE. Maya civilization continued to thrive in the Post-Classic period. Just because they moved, dispersed, reorganized, and changed doesn’t mean they “vanished.” There was a major drought, one that hadn’t been seen for thousands of years, that caused the dispersal of people from some of the major cities. However, other Maya cities like Tulum and Chichen Itza, grew and thrived in the Post-Classic period. Environmental, cultural, and political changes happened around the 900-1000 CE time period that led to the reorganization of peoples. No one vanished, nor did their civilization.

This curriculum claims that they vanished after 900 CE but then says that there are still Mayan speaking people in the area today. If they vanished, there wouldn’t still be Maya people today. Not only are the Mayan languages still spoken today by over 7 million people today, but their cultures also still exist. There are intact Maya communities all over Central America today.  They never “vanished.”

The curriculum claims “American explorers” in the 1800s had heard stories about “mysterious” ruins in the rainforest. These were never “mysterious” as the living Maya people always knew they were there and what the history was. Turning common knowledge of a people into something “mysterious” for another culture only exotifies and others the people. It is part of harmful stereotyping.

It claims their pyramids were simply religious rather than also acknowledging the political aspects of these buildings. It calls Mayan writing “mysterious” and a “code” rather than a complex writing system. It calls Maya homes “huts” despite the fact that they built great cities. It says their calendar was “almost as accurate” as modern calendars, but in reality they made calendars that are more accurate. It says that archaeologist “think” the Maya played a ball game. This isn’t something that anyone “thinks,” it is known in history and in the cultural revival of the Mesoamerican Ball Game among Maya, Mexica, and others today. The only sources cited here are western archeologists instead of actually getting information from Maya people themselves. It just keeps saying archaeologists and “experts” THINK things instead of stating the information as known facts. It makes no mention that this game is played today.

Then is the issue of “human sacrifice.” The curriculum brings up human sacrifice as a result of losing the ball game. The problem is – this terminology is used to demonize certain cultures and justify brutal conquest and genocide which killed millions more people than human sacrifice in Mesoamerica. It makes no mention of the idea that it wasn’t common or a large number of people, the people were usually criminals and enemies, and many religious ceremonies involved only animal sacrifice and ritual bloodletting (consensual) that did not kill the person. Human sacrifice was practiced all over the world but is only ever mentioned in curricula about the Americas at these grade levels and sometimes even at all. It also never mentions human sacrifice when talking about European civilizations or by Euro-Americans despite the fact that it was quite common – just under different names and terms. Is it not human sacrifice to hang, burn, or crucify people in the name of religion? Did the Europeans not carry out brutal executions in the name of their god regularly? Only using the term “human sacrifice” when talking about cultures like the Maya and Mexica (Aztec) serves to further the demonization and stereotyping of these cultures as being “uncivilized” and “evil.” It is Eurocentric and harmful. There is no reason to mention this in fifth grade or without careful analysis. Maya Religion, Gods, Cosmos and religious rituals (scroll to the section on human sacrifice.) It's also important to note that almost all information we have about "human sacrifice" in these civilizations comes from the Spanish who had ulterior motives to justify their genocide. Very little comes from these civilizations themselves, and what does come from their art was generally used to intimidate opponents rather than tell history, and from their writing in the 1500s which was heavily influenced by the Spanish. Most resources on this topic are unreliable. 

Another issue here is that they use words like “groups” instead of tribes or nations. You can read more about the issue with that word here: Native American Curriculum Review: Thoughts on Educational Standards and Textbooks - the word "groups"

They also do not capitalize the word “Native” when talking about people. Always capitalize words like Native and Indigenous when talking about people. Another important note – Maya refers to people, civilization, culture, etc. Mayan refers to language. The curriculum does mostly get this correct.

Chapter 2 is supposed to be about scientific achievements but starts with stating that their religious beliefs gave them an “unclear view” of the world. Do all religious beliefs not do that? Core Knowledge doesn’t claim this about Christianity or Europeans. Why say that at all? Again, this just continues to make them appear “uncivilized” and perpetuates stereotypes. It also states “they didn’t even have the wheel.” We need to stop teaching children that the wheel is a measure of advancement in history. It’s not. Different cultures advance in different areas depending on multiple factors including geography, resources, politics, religion, cultural values and concepts, etc. There was no need for wheels in the ancient Maya environment and society, that doesn’t mean they were not advanced. There is absolutely no reason to point out that they didn’t use wheels other than to again make them look “uncivilized.” This is a great example of racism and Eurocentrism – using European metrics of development to evaluate and judge other cultures and civilizations.

It claims they didn’t use “scientific tools” to calculate how many days are in a year. This is false. They used their own scientific tools to do so. It again calls Maya homes “huts” instead of houses. It calls their cultural customs “odd” which is insulting.

Then it goes back to the false claim of “vanishing” or disappearing. It claims the civilization ended in 900 CE, which it did not. It claims Mayan writing “mysteriously stopped” in that time period, which it did not. It says they “left their cities” instead of saying they moved to and built new cities. It claims the Maya had “been gone for years” by the time the Spanish invaded, but that’s actually what caused the decline of the Maya civilization in the first place. It then says no one actually knows what happened, but again…we do know. We do know factors that caused the shift between the Classical and Post-Classical periods, we do know what caused further decline in the 1500s (Spanish invasion), we do know what happened to them since then and that they still exist.

Moving on to the “Aztecs.”

“Aztec” is a term that was popularized by European scholars in the 1800s and has no real meaning. It can refer to the triple alliance (Tenochtitlan, Texcoco, and Tlacopan), the people (Mexica), or a language group (Nahuatl). In general it encompasses the Nahuatl speaking peoples of central Mexico and the Mexica people. I will use Mexica when referring to the people rather than “Aztec.”

Chapter 3 refers to the people exclusively as Aztec rather than using historically accurate names. This chapter almost entirely focuses on the mythology of human sacrifice again. Read above for some of my thoughts on “human sacrifice.” This chapter claims sacrifices were “regular and generous.” The population of the cities and the Triple Alliance would not have been able to grow to such significant numbers if sacrifices were “regular and generous.” The only real records about Mexica sacrifices come from the Spanish, who lied and exaggerated to justify invasion and genocide. They even claimed the Mexica sacrificed 1000 people a day and in one ceremony killed 80,000 people in 4 days. Both of these claims are mathematically impossible. The reality is that only relatively few human remains in central Mexico have been identified as having been sacrificed, which is much lower than numbers sacrificed by Europeans in their own religious rituals. Another perspective is that most sacrifices should considered casualties of war since it was culturally more important to capture an enemy in battle than to kill them. “There is no such thing as ‘Human Sacrifice’”

Chapter 4 the description of how large the city of Tenochtitlan was isn’t bad here, but the images make it look like the city was small. Tenochtitlan was one of the largest cities in the world in the 1400s. It also doesn’t do justice to the description of the city at all in the “city tour.” It minimizes the chinampas (gardens) despite them being one of the most sophisticated forms of agriculture in history. It makes the education system sound scary and entirely about warfare and even says something about you having “tough teachers” over the years but you’ve "never had one that practices human sacrifices." I rolled my eyes hard here. It minimizes the writing system to “pictographs.” It says the sound of the marketplace is a “ruckus,” but they don’t describe European marketplaces the same way. It inaccurately lists bananas as being a food in Mesoamerica when it’s from Asia and was not in the Americas for hundreds more years. The city tour continues to harp on the mythology of widespread human sacrifice; every section mentions it. It makes no mention of sophisticated water systems and aqueducts, indoor bath houses and toilets, hygiene and cleanliness of the city, libraries, medical knowledge and care, scientific knowledge and invention, etc. It almost entirely focuses on violence, weapons, “fierce warriors,” and human sacrifice as if that’s all that the Mexica ever cared about. It reduces an amazing civilization to a trope of violence.

A note on houses vs huts – houses in the Americas are called "huts" throughout this curriculum, described as being made of mud and straw, or stone "huts" with thatch roofs, etc. In the SAME TIME PERIOD, houses in Europe are called houses and cottages, described as being made with mud and straw, thatched roofs, etc. This is a great illustration of how racism and Eurocentrism show up in this curriculum in an almost “hidden” way if you don’t know what you’re looking for.

Chapter 5 is about the Inca. It starts with a story of violence yet again. There are so many things you could focus on when learning about the Maya, the Mexica, or the Inca, yet this curriculum almost always focuses on violence. This is another example of racism and Eurocentrism.

When talking about daily Incan life it again calls their homes, which were well built and made of stone, “huts” while never describing stone homes in Europe as “huts.” Then for absolutely no reason it says that their homes smelled bad. This reminds me of reading Joy Hakim’s horribly racist opinions in the History of Us curriculum, but I digress.

Chapter 6 focuses on Incan engineering and their amazing road system. However, it commits the typical Eurocentric sin of comparing the development of non-European cultures to European metrics of development. It again points out how the Incans didn’t have wheels or animals to pull carts, despite already mentioning that llamas were used as pack animals. Wheeled carts would made absolutely no sense in the environment of the Andes mountains. They didn’t make wheeled carts because it wouldn’t have worked there, not because they weren’t advanced. They did, in fact, invent the wheel but it was largely used on children’s toys. It then talks about the Incan suspension bridges, which were an engineering marvel and also explain why wheeled carts made no sense in their environment. It does call the bridges engineering marvels, which is nice. But then it claims the suspension bridge over the Apurimac was no longer used by the Inca past 1890. This is incorrect. It is still rebuilt every year by the Quechua people of the region and used to this day. They did not disappear either. They’re not just “the people of Peru” as this curriculum states. I have been to the Andes, I have been in these communities…they’re Indigenous and they still carry their ancestor’s knowledge and pass it down through the generations.

Chapter 7 is the final chapter in this unit and is about the Spanish invasion in the 1500s. It starts with a racist story about the “Aztec” being amazed by Spanish ships sailing in on the coast and calling them “floating mountains.” It also says they “knew nothing of sailing ships.” This makes no sense. The Caribbean and Mesoamerica were one of the most densely populated places on Earth in the 1400s. The Caribbean, the Gulf coast, and the coast of Central America were full of Indigenous port towns and cities, seafaring cultures, and had a vast economic trade network throughout the ocean. Boats were coming and going from the coast constantly. These boats were not “canoes.” They were ocean going vessels. Some Indigenous peoples of the coastal regions made sails even. The Maya had boats as large as Viking long ships. Spanish described these ships as holding around 50 people, because yes, the Maya still existed when the Spanish came, unlike what this curriculum says. The Spanish encountered the Maya. Tulum and other Maya port cities continued to exist throughout the 1500s. Boats of various sizes, including large boats, were common in the region. The Mexica knew what large boats looked like. The Mexica described the Spanish ships as “floating houses” (not “mountains”) because they were a different kind of ship than they were familiar with, not because they didn't know what a sailing ship was. 

The curriculum then also repeats the completely debunked racist story that the Mexica thought the Spanish were gods and that they brought gifts to the Spanish to please them and worship them. This has been disproven multiple times over. Repeating this in history texts is not only historically inaccurate, it’s racist. It is used to make the Mexica look ignorant and backwards. The Mexica Didn't Believe the Conquistadors Were Gods - JSTOR Daily

The story at the beginning of this chapter is just racist, plain and simple.

It calls Cortes a Spanish “explorer,” but as I have discussed in blog posts previously, the early Europeans that came to the Americas were not “explorers” at all, but slave traders and treasure hunters. They came to conquer, not explore. The curriculum uses terms like “conquistador,” “conquest,” and “conqueror” without ever explaining that this means to invade, kill, and destroy. They use those words as if they’re just normal nice sailors. It says he wanted to spread Catholicism and get rich. That may be true, but this is an extremely whitewashed way of saying invade, commit genocide, and take over. It then says Cortes “found” a Native woman to serve as a translator. He did not “find her,” she was enslaved along with multiple other women.

The story claims the Spanish had superior weapons. Guns in that time were not superior by any means. The Mexica had obsidian swords (obsidian blades embedded into wood) that could cut the head off a horse. The were experts with atlatl (throwing spears). They used bows and arrows. Spanish guns were quite ineffective – they didn’t shoot straight, they were heavy and slow to load, and difficult to fire (and could only fire once at a time). The Spanish mostly used swords and lances. The Mexica used atlatl, macuahuitl (obsidian swords), and arrows. Ultimately it was the fact that the Spanish wore extreme armor and rode horses that gave them some advantage, not their weapons. The curriculum makes no mention of the Spanish having to fight their way out of Tenochtitlan because the Mexica were formidable opponents. It makes the Mexica sound completely weak and ineffective against the Spanish when they weren’t.

It also says that the disease smallpox swept through the city which is ultimately why the Spanish were able to conquer it (that and using Indigenous enemies of the Mexica to help them, which of course they then betrayed and violently conquered as well). This may be true, but it’s also possible that the Spanish intentionally poisoned the people of Tenochtitlan which lead to this downfall. 

The chapter then basically says the same racist story about the Inca…they didn’t know what ships were, they were scared of the Spanish, etc. It does mention disease spreading through the Incan empire ahead of the Spanish, which is true. And it at least calls Pizzaro’s massacre of the Inca a massacre and not a battle.

To end the chapter it talks about invasion and genocide as if it’s positive because they “ended human sacrifice” and “brought Christianity.” They didn’t end human sacrifice as the Spanish were well known to routinely sacrifice Indigenous people in the name of their god. There is no positive way to spin genocide as this tries to do.

The teacher guide is largely full of the same issues as the student text. When it comes to recommended additional resources, they do not recommend any Own Voices resources or resources by any experts on the subject. All of the recommended books are problematic in the same ways as this curriculum. It does, however, suggest some online resources from the National Museum of the American Indian which is a great resource. They offer some good online resources for the Maya calendar and math. However, they didn’t suggest the NMAI resources on the Inca, which exist and are just as good as the Maya resources.

It also claims that everything we know about these civilizations comes from archaeologists and by studying ancient ruins. This is false. There are Maya, Mexica and other Nahuatl speaking peoples (Aztec), and Quechua (Inca) people that still live today all over Mexico, Central, and South America. They not only maintain languages, but also the rich cultures, traditions, religions, and values of their ancestors. These people are not extinct, as this curriculum and teacher guide claims. We know a lot about their ancestors from THEM. They are the experts on their cultures and peoples, not archaeologists.

Another major issue I want to highlight in the teacher guide – it directly states that ONLY three great civilizations existed in the Americas before European invasion (which they Eurocentrically call the “Age of Exploration,”) and these are the three. There were many great civilizations before these three and at the same time, and not just in Mesoamerica and South America. There were great civilizations in both places BEFORE the Maya, “Aztec,” and Inca, including Caral, Moche, Olmec, Zapotec, and many more. There were great civilizations in various places north of modern-day Mexico, including the Mississippian, Haudenosaunee, Ancestral Puebloan, and many others. To reduce the Americas to only three great civilizations is racist and inaccurate.

Overall, this unit is racist, Eurocentric, and historically inaccurate. I recommend staying away from Core Knowledge entirely (I have looked at and reviewed other levels, I will be posting those and have more to review). Core Knowledge is a conservative organization that was founded by a known racist and pushes American Exceptionalism, Eurocentrism, and nationalism. It being free doesn't make it safe to use.
