1 - Getting Started ~3 mins
A frog crosses the pond two stepping stones at a time, starting from the bank. Which stones does it land on? Which stones does it never touch?
2 - Watch and Notice ~7 mins
The frog's stepping stones are the numbers on this line. Watch the frog jump two at a time. A landing is the stone it stops on. Say each landing aloud — and listen hard to the end number (the little number on the right, like the 2 in 12).
Now the frog keeps going all the way to 20. What do you notice about the end numbers?
3 - Try It Together ~7 mins
Start on a number the frog already landed on — try 4. Jump two each time. Predict the landing before each jump.
Jump two at a time
4 - Write the Jumps in Your Copy ~4 mins
In your maths copy, write the jumps-of-two landings from 2 to 20 in one careful line:
- 2
- 4
- 6
- 8
- 10
- 12
- 14
- 16
- 18
- 20
5 - Class Challenge ~6 mins
Jump two each time. Before each jump, say the end number.
- Landing after 6
- Landing after 10
- Next two landings after 14
- Two jumps from 16
Frog jumps of 2
