3-Dimensional Fraction Blocks

thingiverse

Fraction Blocks offer an engaging and effective tool for teaching fraction concepts across various grade levels and mathematical abilities. The versatility of this manipulative lies in its scalability and simplicity. For introductory fraction concepts, print base blocks labeled with one, one-half, one-third, one-fourth, one-fifth, one-sixth, one-seventh, and one-eighth, each in different colors for easy identification. Use these blocks to explore how a whole can be divided into equal parts or equivalent fractions, and missing parts of the whole. For more advanced concepts, print student unit cubes and use them to introduce length, surface area, and volume relationships. Explore scale factor relationships between these properties using one-unit, one-eighth, and one-sixty-fourth cubes. Extend this concept by printing other non-regular blocks and observe changes in dimensions, surface area, and volume. The Fraction Blocks' effectiveness lies in their 3D nature, which enhances spatial awareness and aids in understanding area and volume concepts at an earlier age. The files are easy to print and can be customized based on the concept being taught or the grade level of the student. Share your innovative ways of using these blocks!
