Using the Addition Strip Board, the child practises the sequence of addition combinations 1-9, and begins the process of memorisation of the addition tables. The material is composed of a hardboard chart 12 squares by eighteen squares with the numbers 1-18 printed across the top. Stored in a wooden box with lid are the strips used for the exercise, nine red strips divided into squares and nine solid blue strips, both printed with the numerals 1-9.
