Algebra Balance


Add to Cart

$44.99
Unlike any other balance, this balance lets you demonstrate that –1<0. Weights placed on the outer pans represent negative integers, and those placed in the inner pans represent positive integers, making it possible to demonstrate that (–1)+(+1)=0. Great for small-group work, the balance includes 4 plastic pans, 4 plastic canisters, a set of plastic weights and Activity Guide.
