Four-Pan Algebra Balance
Grades 6-12.
Unlike any other balance, this balance makes it possible to physically show that -1<0. Weights placed in the outer pans represent negative integers and those placed in the inner pans represent positive integers. Students use the balance to derive the rules for working with signed numbers, solving linear equations, building identities, and modeling systems of linear equations. Ideal for small group work, the sturdy 17 in. plastic balance comes with four plastic pans, a set of plastic weights, and four plastic canisters. Detailed instructional booklet included.
