This product is a portable version of my Addition and Subtraction Desk Zipper. It can be used in school and at home.
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 Pencil Pouch can be used on student work area or in student's binder. It's available in 0-20 unit increments for lower elementary students and 0-59 for upper elementary students. Please specify increment unit, color, and if for boy or girl when ordering. Instructions for use included.
Allow up to 1- 3 weeks for delivery, depending on size of order. Shipping will be discounted according to size of order and weight.
