Primary 4 mathematics

In Primary 4, learners build fluency with multiplication and division facts, work with larger numbers and begin to see how fractions and decimals connect. They measure and calculate with time, describe shapes and angles, collect and display data, and use everyday language to describe how likely events are. Practical, hands-on activities around the home help make these ideas concrete.
