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!

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!

ReplyDeleteYay! Glad you students like them! Thanks for reading my blog :)

DeleteInterestingly, the difference between consecutive squares will always be an odd number :)!

ReplyDelete1,4,9,16,25,... 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!

What a fun fact! I learned something new today! :)
