Year 3 | Mental Addition Worksheets

The Year 3 mental addition worksheets present a series of partially filled addition number sentences, encouraging pupils to solve them mentally. Following that, learners are tasked with mentally adding 50 and 150 to various provided numbers. In the final section, children encounter eight multiples of 10 and are prompted to mentally shade in three numbers that combine to form a total of 160.

These Year 3 mental addition worksheets will help children improve their ability to perform calculations quickly and accurately in their minds, enhancing their mental maths skills. Successfully performing mental addition boosts children’s confidence in their mathematical abilities, encouraging them to tackle more challenging math tasks with self-assurance.
