Primary 1 mathematics
In Primary 1, children extend their counting well past 100 and begin to see two-digit numbers as tens and ones. They add and subtract small numbers using objects, fingers and simple strategies, and they measure and compare lengths using repeated informal units. They also explore patterns, shapes, simple data and the language of chance.
