Math Facts - Numbers, Shapes, Colors

3D model description

UPDATE: I have included some lesson plans in PDF format to go along with the printed items. Check back often for more!

This is a math manipulative that allows for many different lessons for addition, subtraction, multiplication and division.

It also allows for easy learning of:

Grouping

Probability

Combinations and Permutations.

Venn Diagrams

The 125 small parts can be stored in the included locking storage bin that I made with my pencil box customizer: http://www.thingiverse.com/thing:147178

I think it is great that the storage box for these math manipulatives comes from the longest math problem I ever wrote!

I am currently printing one set to give to a 4th grade teacher in my area.

3D printing settings

Print out the plate of 25 parts in 5 different colors. You can pause the print after 5mm to make the numbers print in a different color for contrast. I recommend 2 shells with 10% infill and 4 top and bottom layers. I have included broken up sets for all numbers and shapes, so you can print extra parts if necessary.

Print the body, lid and key with 4 shells with 10% infill. You may want to print multiple keys, in case you misplace it. The lid and body snap together at the hinges with a slight bend of the wall on the lid.

More PDF lesson plans will be added soon!
