3D Vertical Fraction Strips

The manipulative I made is a 3D version of fraction strips. Each strip is a rectangular/square piece that slides onto individual pegs, making them both sturdy and easy to play with. I’ve also made it so that the fraction blocks stack vertically (rather than lining up horizontally), to indicate height as value and amount. I wanted to build something to help the student to visualize and deepen their understanding as they explored fraction relationships. What was most important to me was having all the fractions mounted on one platform with the 1 (whole) always being visible, so that the student could begin to grasp how all the smaller parts relate to the whole.
