Subtraction in Action!
Lakeshore Learning Material's Subtraction Machine is a new addition to our line-up of fun and educational toys for children's use during their visit to the Ann Arbor District Library! The subtraction machine gives kids a hands-on way to practice their math skills with immediate feedback on their answers. The toy features a grid of 81 subtraction problems; when you press on the equation button, the answer pops up! The equations reinforce whole-number, single-digit subtraction. The library provides a variety of toys and manipulatives at each location. These tools aren't just fun, they help young people learn.
