Rekenreks are a great visual tool for building number sense and practicing addition and subtraction strategies! If you do not currently use them, I highly recommend that you check them out!

Rekenreks are strings of ten beads, with each string having 5 red beads followed by 5 white beads. They help kids see numbers 5 and 10 as "anchor numbers" when composing and decomposing numbers. For example, when adding 8+6, kids can see 8 as "5 and 3 more" and 6 as "5 and 1 more". Because both sets of 5 are red, it's easy to see that you can make a ten. 10 red beads + 4 white beads = 14.

This file contains picture cards for various strategies on the Rekenrek. It also contains numeral or equation cards for each strategy that can be used to create matching or "memory" centers.

Strategies included:

- Making 10

- Doubles

- Near Doubles

- Numbers 1-20 (standard formations)

- Adding 0

- Adding 1

- Counting Up

****Please note that these centers are part of my "Number Sense BUNDLE"! Do not purchase if you own the bundled set!****
