What Year 4 explorers learn
- Year 4 Numbers to 10,000Read and write four-digit numbers, say what each digit is worth, find 10, 100 or 1,000 more or less, and round to the nearest 10 or 100.

- Year 4 Division FactsUse the 6, 7, 9, 11 and 12 times tables backwards to divide, find missing numbers and solve sharing stories.
- Year 4 DecimalsWrite tenths and hundredths as decimals, say what each digit is worth, compare decimals and add and subtract tenths.
