Add and Subtract Box

This wooden Add and Subtract Box features brightly coloured individual wooden
tiles, with a combination of addition and subtraction sums from numbers 1-9.
Introduce numbers at an early age - lots of simple sums can be worked out and
with repeated use, basic numeracy will become second nature! The practical
wooden tray makes this toy a great travel companion and all of the pieces can
be stored inside. Helps to develop dexterity and concentration. Made from high
quality, responsibly sourced materials. Conforms to current European safety
standards. Consists of 81 play pieces.
