Product Description

These easy-to-manipulate disks provide hands-on practice for developing number sense. Color-coded according to place value, the foam disks allow students to visually track what happens when they regroup numbers in both addition and subtraction. And they help illustrate that multiplication is the same as repeated addition and division is the same as repeated subtraction. A re-seal-able poly bag plus instruction sheet included. (Grades 3-6) 140 Disks (20 for each of 7 values)

Initially, I planned on making these myself with a circle die cut and different colored construction paper. I decided that the paper discs would be to flimsy and bothersome to grasp. I purchased these feeling assured that they were specifically referencing Singapore Math (which is the program we use). Low and behold we receive the product and sit down for our first lesson, only to realize we are missing the entire 20 discs of the thousands and a few from the other place values. Honestly, if we were missing a few from each, I would not have bothered--but an entire place value?! I applied for a replacement, which is a simple process, but I am just annoyed that we have to delay our lesson....As far as the actual product, the discs are colorful, durable and easy to grip. I will be glad when a full set arrives.

I needed this for Singapore math instruction. We'd been using paper cut outs that we'd found online. These are smooth to touch and colored coded.

Okay, so I'm going to preface this by saying the ridiculous s&h price is behind most of this review. Find another seller who will not charge you an arm and a leg for s&h. I'm not impressed with these discs, at all, considering the price I paid for them.

They came on time and as expected. I am excited about using them this fall with my students as a concrete way to show 2 and 3-digit addition and subtraction.
