Number Rack Activities for Kindergarten and First Grade Math Centers

In this video, I share 6 rekenrek math centers you can use tomorrow in your classroom all using math racks or number racks!

These math workshop stations are easy to prep and can be used again and again, perfect for kindergarten, first, or even second-grade students!

Rekenreks, also called math racks, number racks, or arithmetic racks are a great tool to encourage students to develop more sophisticated counting strategies beyond counting objects one by one. A rekenrek, or bead rack, has two rods, with 10 beads each, five red and five white.

Because of its structure with 10 beads in each row and 5 of each color, rekenreks can help students learn anchors to 5 and 10. Similar to a 10 frame, it helps students see numbers as groups that can be recognized, manipulated, and used to find multiple solutions for problems while developing their number sense.
