Product Description
Designed to be a self-teaching student tool, this device helps lower elementary students learn basic addition and subtraction facts, while working independently.

Older elementary students, lacking basic addition and subtraction skills, are able to perform complex, multi-step operations without getting bogged down by not knowing basic math facts while learning basic facts with accuracy.

When adding, student moves zipper to first addend. Student then moves the zipper up the number of spaces of the second addend. In other words, student is counting up to correct sum. Zipper is moved the opposite direction in performing subtraction.

Zipper desk device attaches to individual student desk via an elastic band. Therefore tool is readily available to student. It's available in 0-20 unit increments for lower elementary students and 0-59 for upper elementary students. Please specify when ordering. You may also specify specific colors if available.
