I made these charts into posters, laminated them and hung them on a bulletin board in my classroom. My students refer to them every time they are adding or subtracting. You can also print them about 4 to a page, or 2 to a page and cut and have students glue into a notebook for reference. I included a color version and black and white version. You can print the black and white version onto color copy paper.

You can also print 4 to a page, cut and put on rings and hang onto a plastic frame to use as table anchor charts. I did this for some students as extra support, and all my students wanted to use them. I got the frames on Amazon. They are double sided standing picture frames. I bought in white and spray painted to match the colors in my classroom.
