Children learn to count forwards and backwards in steps of 10, 100, 1,000, 10,000, and 100,000 starting from any whole number up to 1,000,000.
In Year 5, children build on earlier counting to count forwards and backwards in steps of powers of 10—such as 10, 100, 1,000, 10,000, or 100,000—for any given number up to 1,000,000. Rather than always starting from zero or a round multiple, pupils work from irregular starting values (such as counting up in ten-thousands from 432,650).
Errors most often occur when a step crosses a place value boundary, particularly when counting backwards across zeros. For example, when counting back in thousands from 300,450, children may hesitate or miscalculate the transition to 299,450, often changing only the thousands digit and neglecting the regrouping needed in the ten-thousands and hundred-thousands columns.
Tasks provide structured practice through sequences where children keep counting forwards or backwards by the same step, or select the correct next number from options. Other worksheets challenge them to spot and correct an error within an equal-step sequence, or determine how many times they must count on by a specific power of 10 to reach a target value.
