I’m excited to be sharing an easy project with you today–one of my favorite math tools: rekenreks!
I don’t know about you, but I love to use rekenreks in my classroom. If you’ve never heard of rekenreks before, you will! These arithmetic racks consist of two strings, with a row of beads on each string. Each row is traditionally made up of five red beads and five white beads, but you can use any two colors you like. They are great for helping students to understand number concepts such as basic addition and subtraction, subitizing, and decomposing numbers. These have become an essential part of my math workshop, but they are an expensive purchase!
What I’m about to show you is a much better method of making rekenreks that will last a lifetime!
Yeah, I know this was not the best setup. Don’t make fun. After drilling the holes, get some sandpaper and give the edges and the areas around the holes a quick sanding.
Trim the excess string along the back. This is what the finished product will look like!
