This handcrafted puzzle teaches the principles of addition and subtraction. Each piece is a multiple of one so children can see the progression of number value with the size of the piece. If you lay the 7 piece down and place the 4 and 3 next to it, you will see the values are the same.
The puzzle is crafted of wood from sustainable forests, stained and finished with all non-toxic products. Can be wiped clean with a damp cloth. Because we make FREE REPLACEMENT PIECES, the puzzle can be enjoyed for years to come.
The puzzle pieces are almost 1/2" thick; puzzle weighs 3 pounds.
