Rekenrek Math Tool
thingiverse
What is a rekenrek, you ask? It's kind of like a simplified abacus used for arithmetic and number sense in the primary grades, of course! Print some out and make them available to the elementary math students in your life and watch their addition, subtraction, and number composition skills soar! Or just listen to them slide the counting rings back and forth until it drives you batty, either way. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Notes: Note: I included thin supports for the axel as part of the design which easily break away when the counting rings are moved.
