Step 3 Objective
Recognise and extend number sequences formed by counting from any number in steps of constant size, extending beyond zero when counting back.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
Examples of what pupils should know and be able to do
Count on and back, for example:
- from zero, count on in 6s, 7s, 8s, 9s to about 100;
- count in 11s to 132, then count back. Can you go past zero? What happens if you start at 133?
- count in 25s to 1000, then back.
- count in steps of 0.1 to 5.0, then back.
Pupils recognise that counting in steps of constant size produces sequences of numbers that can be continued in either direction.
