MPACT engages students in the excitement of 3D making—with everything from quick-dry clay and cardboard to digital tools for 3D modeling and printing. Students engage in computational thinking (CT), spatial reasoning, and mathematical concepts through design and hands-on making projects.

  • Four units—one for each of grades 4–7—guide students in design and making with purpose, while providing rich opportunities for developing deep understanding in three content areas:
    • Math concepts such as dimensionality and 3D measurement (e.g., volume)
    • CT practices such as creating and debugging algorithms
    • Spatial reasoning such as mental rotation, key to later success in STEM
  • A 2-year study showed that 4th–5th graders demonstrated significant learning gains on an assessment of math, computational thinking and spatial reasoning.
