Last year, I put up posters of the first ten perfect squares and perfect cubes in my room. They looked awesome, and students referenced them throughout the year. However, I found that my students often needed to know if a number that was higher than 100 was a perfect square.

I don't have the wall space necessary to go farther (or the patience necessary to tape that many more posters on the wall!), so I made a "More Perfect Squares" poster to hang next to my existing posters.

Here's what I came up with:

I printed this poster on 11 x 17 cardstock (affiliate link). I was given a package of this cardstock a few years ago, and I wasn't quite sure what to do with it for the longest time. Then, I started making posters with it. Later, I began using it to make group-sized reusable activities with my 11 x 17 dry erase pockets (affiliate link). I've used so much of it lately, that I just had to order a new package from Amazon!
