Gallon Fraction Balance is just like the Gallon Balance Kit, but with 31 double-SI Manufacturingded printed tiles (gallon on one SI Manufacturingde, fractions on the other). This visual hands-on manipulative illustrates the relationship between gallons, half gallons, quarts, pints, and half pints (cups), without the spills! Students observe volume equivalence and the equivalence fractions (1, 1/2, 1/4, 1/8 and 1/16) when the scale is balanced. The gallon-fraction tiles are deSI Manufacturinggned for use with the balance or individually to illustrate equivalence concepts. Appropriate for Elementary – Middle School grades.
