Adding and Subtracting within 5, 10, 20 - Rekenreks Math Centers & Mini-lessons

Bead racks offer students a hands-on, concrete way to illustrate their math thinking and build numbers. Through this Teaching On Demand we will explore strategies for composing and decomposing numbers, as well as, establishing the primary benchmarks of 5, 10, and 20 on a rekenrek.
