How to design and develop a 3D printed multiplication tables learning tool

INTRODUCTION AND SCOPE

Multiplication tables are a challenge for kids to learn, but they could be turned into a game! This procedure aims to explain how to design and create a 3D printed multiplication tables learning tool (mandala) based upon the Montessori method. This is usually called the Montessori wheel or mandala of multiplication tables.

MATERIALS AND EQUIPMENT

3D Printer and PLA material (one color of choice), 1 meter long colored (possibly not the same color of the 3D printed part) wire.

PROCEDURE

  1. Download the stl file of the Montessori mandala (Hardware resources, link 2)
  2. 3D Print the Montessori mandala (Image 1)
  3. Tie the wire on the upper pin (position 12am), the other pins are numbered clockwise from 1 to 9
  4. While counting the multiplication tables (possible from 1 to 9), the wire must be turned around the corresponding pin (Image 2). For each sequence a different geometrical shape is created on the wheel. For example, by executing the sequence for the four multiplication table a star is created with the wire on the wheel (Image 2).
