Heads In, Hearts In: Hungry Hedgehogs

What you need to know:

An inequality is a math sentence in which two different numbers are separated by a symbol that shows their relationship. When one number is bigger than another, they can be separated by the greater than sign (>). For example, 5 is bigger than 3, so that would look like 5>3. When one number is smaller than the other, they can be separated by the less than sign (<). For example, 2 is less than 9 so that would look like 2<9. When trying to remember which symbol to use, remember that the small ends of the < and > symbols always point toward the smallest number, for example: 3<20 (3 is less than 20) and 20>3 (20 is greater than 3). An equation is a math sentence in which the two sides are equal. When two numbers are the same, they can be separated by the equal to sign (=). For example, 6 is equal to 6 so that would look like 6=6.

What you will do and learn:

In this activity, you will help feed crickets to a hedgehog. You will take two groups of crickets and decide which symbol to use to describe whether one number is greater than, less than or equal to.
