Unlike any other balance, this one makes it possible to physically show that -10 weights placed on the outer pans represent negative integers and those placed in the inner pans represent positive integers
  • When you place a weight in each pan on one side of the center post, the balance remains level as (-1) + (+1) = 0
  • Ideal for small group work, the balance comes with 4 plastic pans, 4 plastic canisters, a set of plastic weights and a teacher's booklet
  • Some assembly required
  • Ages 11-17
  • Small parts. Not for children under 3 years.
