• Uses numbers from 1 to 9 in counting and comparison. (Real objects and repeated events like clapping to be used for counting)

•  Reads and writes numerals from 1 to 9.

•  Adds and subtracts using real objects and pictures.

•  Adds and subtracts the numbers using symbols ‘+’

and ‘-’.

•  Approaches zero through the subtraction pattern (such as 3 – 1 = 2, 3 – 2 = 1, 3 – 3 = 0).
