Year 3 mental arithmetic questions

This week we round off the term with some nice straightforward questions.

The first four questions in each set are about rounding to the nearest 10 or 100. Watch out for children who round to the nearest ten when they are meant to round to the nearest 100.

The next four questions look at doubling and halving 2-digit numbers and 3-digit multiples of 100. Doubling and halving are powerful mental arithmetic skills to possess and can help answer quite tricky questions easily, so it is well worth getting children to learn, off by heart, the doubles and halves of small numbers.

Finally, a couple of questions on the properties of squares and cubes. All quite straightforward!
