Children learn to count forwards and backwards in steps of 6, 7, 9, 25, and 1,000, spotting patterns and finding missing numbers in sequences.
In Year 4, children extend their counting skills to move fluently forwards and backwards in multiples of 6, 7, 9, 25, and 1,000. While earlier years focus on smaller steps such as 2s, 5s, 10s, and 100s, children now tackle these larger, less intuitive jump sizes to support their times tables up to 12 × 12 and their grasp of four-digit numbers.
A frequent stumbling block occurs when counting crosses a hundred or thousand boundary, especially when counting in reverse. For example, stepping backwards by 25 through a hundreds boundary (such as moving from 1,025 to 1,000 and then to 975) often trips children up. In steps of 7 or 9, pupils can also lose their rhythm if they attempt to calculate each individual jump by counting on their fingers rather than spotting the regular digit patterns.
Practice activities use simple sequences to build confidence with these steps:
- Keep counting by the same step or choose the next number to finish an incomplete sequence.
- Count backwards in equal steps to strengthen subtraction and reverse number sense.
- Spot mistakes in a sequence to correct the wrong number.
- Calculate how many times you must count on to get there, helping bridge the gap between counting and multiplication.
