Early Childhood Teaching Aid for Digital Addition and Subtraction

1. Model Introduction:

This 3D Printed ten-frame addition and subtraction teaching aid is a math enlightenment tool designed specifically for young children, making abstract addition and subtraction operations intuitive and fun.

The mold includes two sets of ten-frame card slots, along with circular counting chips and number symbol modules. Children can intuitively understand the principle of 'making ten' by arranging the counting chips, for example, by splitting numbers into '10 and something', easily grasping the logic of carrying in addition. The formula slot below allows for free combination of numbers, addition/subtraction signs, and equality signs, allowing children to manually construct complete addition and subtraction equations, transitioning from concrete operations to abstract mathematical expression.

It not only exercises children's hands-on abilities but also helps them develop number sense and understand the essence of addition and subtraction. It is a practical tool for kindergarten and early elementary school children to learn addition and subtraction, making math enlightenment say goodbye to tedious calculations and become an exploration of learning through play.

2. Printing Notes:

This model can be printed using AMS dual-color single plate printing to save time, or single-color multi-plate printing without AMS. The circular counting chips and number symbols can be printed by pausing and changing filament (only once). If you want to achieve a distinction between addition and subtraction, you can adjust this by using 4-color printing (adjusting some colors yourself) or multi-plate printing.

3. Model Optimization:

I will make adjustments based on your needs and suggestions in the future. If you have any ideas, please leave a comment or send me a private message. Thank you.
