thingiverse

TEACH MATHEMATICS PRACTICALLY Teach how to add, subtract, multiply and divide different fractions practically. These pie fractions are designed with the maker, children and teacher in mind: - The entire set stacks into a neat, stable pile, for storage. - Each pie slice can be stacked on top of any other, enabling the children to compare them (e.g. 1/2 = 1/3 + 1/6, as in the photo) - Empty tins stack on top of each other. - Designed to minimise plastic usage and print time. AVAILABLE FRACTIONS 1/2, 1/3, 1/4, 1/5, 1/6, 1/8, 1/10 and 1/12. Each piece has the accompanying decimal equivalent written on top. COST One full set (8 full tins) requires 244g of plastic and approximately 20 hours of printing using the settings below.
