Middle School Invisible Math Posters: Calming Classroom Decor Bulletin Board Set

This set of 20 posters is great for reminding students of often forgotten math principles. These posters have calming watercolor backgrounds and are perfect for displaying on a bulletin board in your Algebra or General Math classroom. Please take a look at the preview file for a visual overview of everything included. They are the same as my other set of colorful invisible math posters, just with different fonts and design.
