• Number: Counting, Operations
The name Rekenrek literally means calculating frame. The development of the Rekenrek is attributed to Adrian Treffers from the Freudenthal Institute in Holland. The Rekenrek is basically a bead frame where the beads are grouped in fives. Five beads of one colour alternate with five of a different colour. It is felt that young children anchor on five and then ten and use these numbers to support calculation.
Addition, calculate, counting number names, subtraction, sum, total.

Support and Complementary Materials
There are a variety of Rekenrek related materials such as beadstrings. The smaller beadstrings (up to twenty beads) are typically configured in fives.
Larger beadstrings (100 beads) are configured with ten beads of each colour. Students anchor on the ten rather than the five.
