What is a rekenrek?
A rekenrek, also called an arithmetic rack, is a counting frame with rows of ten beads on horizontal rods. Each row of ten is split into five red beads and five white beads so students can read quantities in groups of five rather than counting one by one. The standard 20-bead rekenrek has two rows, while a 100-bead rekenrek has ten. Developed for early number sense, it helps children in kindergarten through grade 2 subitize, make ten, and build addition and subtraction strategies. A rekenrek generator turns a short description into a clean, labeled bead rack image so you can skip the drawing and go straight to teaching.
How to use a rekenrek
20-bead vs 100-bead rekenrek
A 20-bead rekenrek has two rows of ten and is the right tool for building fluency with numbers to 20, including pairs that make ten and early addition and subtraction. A 100-bead rekenrek has ten rows of ten, giving one hundred beads in total. It extends the same five-and-five structure to larger numbers, supporting counting by tens, place value, and two-digit addition and subtraction. Many teachers introduce the 20-bead rack first in kindergarten and grade 1, then move to the 100-bead rack in grade 2 as numbers grow and students are ready to work with tens and ones.
Classroom strategies and activities
Printable and clipart rekenrek uses
Beyond a physical rack, a printable rekenrek is useful for worksheets, anchor charts, slides, and assessments. Generate a blank 20-bead rekenrek for students to color beads on, or one already showing a number to model a strategy on a handout. Rekenrek clipart drops cleanly into lesson slides, task cards, and learning platforms where you need a tidy bead rack graphic. Print on card stock and laminate for a reusable mat, or export the image and post it online so students can annotate it from home. Because the five-and-five coloring is drawn in, every copy stays consistent and easy to read.
