Buy Rekenrek

The counting method in a math rekenrek is similar to the Danish abacus. You begin by sliding all the beads towards the right and then slide the beads towards the left for solving a problem. Then count from left to right.

This deck of 68 cards contains six different visuals for each number 0 through 10 plus two instruction cards. Each number 0 through 10 is represented in the deck with tally marks, rekenrek, ten frame, dot pattern, numeral, and finger pattern. The written numerals are in a handwriting font so that the 4 has an open top and the 6 and 9 are easily differentiated.

The MathRack (aka Rekenrek) is a unique tool that allows children to develop number sense at their own pace. The MathRack 20 is modeled after the rekenrek/arithmetic rack from the Netherlands. With the built-in 5 & 10 structure, MathRack tools help children build number relationships that lead to more advanced strategies.

The rekenrek, or arithmetic rack, was designed by Adrian Treffers, a mathematics curriculum researcher at the Freudenthal Institute in Holland, to support the natural development of number sense in children. Smaller versions consist of two rows of 10 beads. Larger versions with ten rows of ten beads are also available. Each row is made of five red beads and five white beads. This allows students to make mental images of numbers. Using 5 and 10 as anchors for counting, adding and subtracting is obviously more efficient than one-by-one counting. This tool provides learners with the visual models they need to discover number relationships and develop a variety of addition and subtraction strategies, including doubles plus or minus one, making tens, and compensation, thereby leading to automaticity of basic facts.

Hi friends! This is Emily, and I am excited to join Kristin on this journey of helping to improve math instruction and share ideas with all of you. For my first post I wanted to share an idea with you that I started doing last year with my class during the first week of school. If you make rekenreks with your class I would love to see pictures and hear what your students think about them. Feel free to post any pictures or comments!
