Sand Castle Math Practice
Make your own 3D printed sand castle molds and show off your mathematics at the beach!
Math connections: Geometry, mold design
You'll be able to practice your arithmetic all day long while having fun in the sand.
The molds act sort of like a puzzle piece and can be expanded upon with more molds.
A blank puzzle piece was included in 123D format so that anyone can remix and add their own touch to the set.
Print with the open side facing up.
Material you use shouldn't matter.
It takes around 45-60 minutes per sand castle mold.
