The only balance that lets kids visualize that -1 is less than 0. Weights placed on the outer pans represent negative integers and those placed in the inner pans represent positive integers. Great for small-group work, the balance includes 4 plastic pans, 4 plastic canisters, a set of plastic weights and activity guide. Some assembly required.
