Math Calendar Part 2

This recording shows another part of our math calendar routine. Here, we take whatever day of school it is...in this instance, it was the 57th day, and figure out whether that number is prime, composite, and/or square. We do that by finding all the factors of that number, and along the way, learn the divisibility rules for various numbers. (The video may take awhile to load.)
