1 - Getting Started ~3 mins
Two stories, same numbers:
Story A: 9 swallows sat on the wire and 4 flew away.
Story B: Niamh has 9 stickers. Cian has 4. How many more has Niamh?
Hands up: same kind of story, or two different kinds?
2 - Watch and Notice ~8 mins
Three stories. Each one already has jumps drawn on a number line.
Take-away means some leave or are used up.
Difference means we compare two amounts: how many more, or how far apart.
Look at where the jumps start and where they land. For each story, decide: did some leave, or are we comparing two amounts?
Same numbers can tell two different stories, and both write with −.
3 - Try It Together ~10 mins
Today we explore stories on the number line. For each story, first say: did some leave (take-away), or are we comparing (difference)? Then show the jumps on the number line.
We will try:
- 8 apples on a plate and 3 eaten
- 10 points and 7 points, how many more?
- 15 birds on the wire and 6 flew off
Story jumps within 20
4 - Write the Sentence in Your Copy ~3 mins
Look at the board: 9 swallows sat on the wire and 4 flew away.
The matching sentence looks like this: 9 − 4 = 5.
In your maths copy, write that full sentence with − and =.
5 - Class Challenge ~10 mins
Today we work through these story sentences together:
- 10 − 4: ten grapes, four eaten
- 12 − 9: our team has 12, visitors have 9, how many more?
- 16 − 7: sixteen beanbags, seven out to the yard
For each one, say take-away or difference first, then show the jumps and check.
