Twenty frames are used to help children learn counting as well as addition and subtraction practice with numbers 1-20. We have added the idea of dividing the board into quadrants with engraved lines through the middle. This helps your child quickly identify where each number is by seeing them as groups rather than counting one by one.
We include thirty unfinished, natural wood balls (each measures 1/2″ in size). The twenty frame is made from dark walnut wood and finished all naturally with linseed oil and beeswax. The board is about 3×12-inches.
