Exploring number bases is another opportunity to make strong connections with mathematics and history within Cosmic Education. Children love to count in other number bases—what fun to find out that if you are 7 years old in base ten, then you are also 13 in base four! Come explore this chapter of your mathematics album with us—we will review numerations, conversions between bases, and operations in different bases. We’ll also connect this chapter with history, such as exploring the Mayan base twenty system (with a sub-base of five), and the Sumerian base sixty system.
