Rekenrek

What is the Rekenrek?  This Dutch word means arithmetic rack.  It helps children support the natural development of number sense.  Based on the concept that it is better to use 5 and 10 as anchors for counting, adding and subtraction, the Rekenrek is a tool that allows learners to create models and visualize number relationships while developing a variety of strategies for facts up to 20  or 100.  This includes doubles plus or minus, unitization (decomposition of numbers), hierarchial inclusion, subtraction, makings tens, compensation, increasing number and operations in bas 10, and much more!  Perfect for all grades K to 4
