This is a one-page copy master that can be copied onto two different colors of paper. Each student will receive a couple of sheets of each color, cut out the boxes, and keep them in a baggie or envelope with their class materials so that they have manipulatives that can go where they need them to go. The tiles can be used for simple counting and sorting, integer practice, and the distributive property...all the way up to solving equations and factoring polynomials!!!
These are not Base Ten!
