Snap Stick, Bar, Interlocking, Math

Snap Sticks/Bars (100mm to 10mm long, 3mm thick, 8mm wide) . Lengths are center-center measurements.

They are designed for easy assembly by young children. They can be used to make shapes in elementary geometry or make sense of 1D (linear) concepts such as curve lengths or perimeters. The 10mm piece can be hard to snap into. All the rest are relatively loose.

Print some of various lengths and see how children can make with them. As alwasys, remember to observe safety rules when working with children.
