3D model description

This is a set of math manipulatives I created for my daughter. They are commonly used in special education programs. (Popular in the UK, I believe.)

For best results, print each number out in a different color (See example.)

There are many commercial and freely available activities that can be used with this type of manipulative. Examples include:

Good for use as practice 3D printing objects the parts do not require any structural support.

(The base is 5x5 since that is the maximum size for my printer...)

**5x5 base now has pegs slightly smaller to allow a bit more "give" to placement of the manipulatives.

3D printing settings

The base is entirely optional. I recommend, if possible, printing out 2 to 4 sets of the pieces (2 "ones", 2 "twos", etc...), preferrably each number assigned a distinct color.
