Unlike any other balance, this one makes it possible to physically show that –1 is less than 0. Weights placed on the outer pans represent negative integers & those placed in the inner pans represent positive integers. When you place a weight in each pan on one side of the centre post, the balance remains level as (-1) + (+1) = 0. Great for small group work, the balance comes with four plastic pans, four plastic canisters, a set of plastic weights & Teacher's Booklet.. Suitable for kids age 11 - 17 or in Pri 5 - JC 1.
