Do you use math tools or manipulatives in your math instruction? I recently did a post about using the Rekenrek, a tool founded by a researcher in Holland. My students love it. I have several other tools that students can access at any time, but this one is their favorite. I also have number lines, hundred boards, snapping cubes and other counters. We use these a lot, especially as I teach first grade (ages 6-7). Do you use tools to support your math instruction?
