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 More Perfect Squares poster on 11 x 17 cardstock.

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.

I’ve used so much of it lately, that I just had to order a new package from Amazon!

Interestingly, the difference between consecutive squares will always be an odd number :)! 1,4,9,16,25,... have difference 3,5,7,9,... which are also consecutive :)!

This means that from 2 consecutive square numbers, I can always find the next square. Out of your list, 529 and 576 are perfect squares. To find the next number I just find the difference: 576-529=47, pick the next odd number which is 49 and then add it to the largest square to obtain 576+49=625! Which is the next item on your list :)!

Keep up with the good work!

I have had these for a while, and FINALLY this year I got them laminated and posted in my room. I have loved seeing kids' faces when I pointed them out the first week of 8th grade, and their eyes popped. "OH, that makes so much more sense now!" Thank you for sharing all your ideas!
