Perfect for Algebra students working on factoring trinomials or difference of squares!
This is the only 30 x 30 chart on TPT that is "portrait" so students can keep them in their 3 ring binder and be able to look at them without having to turn them sideways. I have my students put it in a sheet protector so they can find it quickly.
Square numbers down the diagonal are bordered and shaded for quick reference.
Note: This prints out sooooo much better than it looks in the tiny thumbnail on this site.
This file also contains a product catlogue for my store here on TPT. I hope you will find my other products to be useful too.
