If you didn't click the link above (and you really should have), here's my inspiration image:
I decided I wanted to simplify things a bit and just print the numbers directly on the squares and cubes. This also let me do cubes higher than 216.
Here's how they turned out. I printed them on colored paper and laminated them. As soon as I'm allowed back in school, I'll be hanging them up above my number line!
I just LOVE looking at these!
I also made a title to hang next to them:
Here's a close-up of one of the squares:
And one more picture just because I got carried away taking pictures because I love these posters that much!
Now, onto perfect cubes! My husband graciously used his geogebra skills to make the images of the cubes for me. Thanks Shaun!
I also made a sign to hang next to the perfect cubes!
Did you notice that I used the same colors for both sets of posters? This way, 1 squared and 1 cubed are the same color. 2 squared and 2 cubed are the same color, etc. (The first time I printed these I got the colors off. It bugged me so much I had to print another set.)
If you want to download these posters for your classroom, I've uploaded them here as editable Publisher files and non-editable PDF files. For the Publisher file, you'll also need to download the font HVD Comic Serif Pro or substitute your own favorite font.
If you prefer Clarissa's version with the pre-cut numbering, you can download her files here.
Update 7/28/16: Someone pointed out that my poster for 9 was actually 4x3 instead of 3x3. Oops! I've corrected the file and uploaded a new version. Now, I just have to reprint that one and laminate it. Guess it's a good thing I haven't hung them up in my classroom yet...
Update 7/28/16: My husband wrote a blog post that includes the Geogebra code to create your own cubes if you so wish.
