Interlocking Gram Unit Cubes Available Upon Request

Gram Unit Cubes (LER 305) are perfect for teaching mathematical and scientific concepts. Use the cubes to teach counting, sorting, and classifying skills to younger students; fractions and the four operations to middle grade students; and concepts such as density and mass to older students. describe the fraction that represents the number of blue cubes in the linked rod. Three out of five cubes are blue, thus the fraction is 3/5. Find the fraction represented by the red cubes. It's 2/5. All of the cubes have been described, so 3/5 + 2/5 = 5/5 or 1 linked bar. Continue using models to subtract, multiply, and divide fractions with the cubes.
