Montessori Addition Board Set

thingiverse

This is an adding material that goes along with many games and activities designed or inspired by Montessori play-based learning. For ages 3 to 6. It's small, comes with a lid, and there's room inside for a laminated worksheet and small white board marker. It's an intermediate print, and needs a stable set up because it's big and flat. If I reprint I'll likely make the strips taller, as they’re a little light for my taste. Strips and Lid are scaled slightly down to provide tolerance for thermal deformations in all 3 files. Please share any improvements.
