Hands up for lift-off! We count down from 10 together: 10, 9, 8… zero, blast off!

Now try from 15. Can we count all the way back to zero without starting again from the top?

Three counting journeys on the number line. Watch where we stand to start. The first number we say is the next one along.

For the last one, say the next number after 17 before we step.

Now we walk the number line ourselves. Stand up beside your desk and pretend the floor is the number line.

You are standing on the start number, so you do not say it. Take one small step and say the next number. Keep stepping until you reach the last number. Counting on, step forward. Counting back, step backward.

• Start at 5. Count on to 9.
• Start at 12. Count on to 16.
• Start at 14. Count back to 10.
• Start at 18. Count back to 15.
