Here is a collection of colorful numbers that can be used to separate your students into five different tables while assigning a/b partners. The colors correspond to the Sprogs Counting Colors Rug. Teachers may use the colors, numbers, and letters as different grouping opportunities. https://www.schooloutfitters.com/catalog/product_family_info/pfam_id/PFAM30164

The rug is not necessary to use the numbers.
