A Variation Of B-Day Cards: Teaching Perfect Squares

Learning Perfect Squares With Birthday Cards

So, what's this perfect square stuff all about and how do we remember it? Time to create some square root birthday cards

1) Think of five people who you normally write birthday cards and write what age they will be this coming birthday (including yourself)

2) Let's figure out what their birthday is in "square root years" 

     Since we know that a square root undoes something squared, all we need to do is square their age.

Example: If your 10 years old, then your also Square root of 100 years old (10^2 or 10 x 10 = 100)

Therefore, square each age to get their age in "square root years". 

3) Now, create them a happy birthday card but replace their age with their square root
