Compare numbers and sums using symbols <, >, and =

In this 1st grade lesson, Mathy my mascot and I compare numbers and sums using the "alligator mouth" symbols < and > and the equals sign =.

For example, we compare 7 and 2 + 4. Since the sum 2 + 4 is 6, and 7 is greater than 6, we write 7 > 2 + 4.

Of course children must have learned how to compare numbers less than 10 (for example, comparing 6 and 9) before watching this lesson, but it is a natural extension of simple comparisons and helps children learn the concepts behind the inequality signs -- and also the correct way to use the equals sign.

In the end, Mathy has a silly word problem for us to solve! But, I turn it around and ask the kids: What COULD we ask in this situation?
