Math Story: Find the Change
Name:
Date:
Today I am practising: finding how many joined or left when the change is unknown
1
A jar has 5 marbles. Then it has 9. How many marbles were added?
2
Show 5 and 9 on a number line. Count the hops.
3
There were 14 stickers. Now 8 are left. How many were used?
4
Write an equation with a box for the unknown change.
5
Explain why the jar story is not asking how many marbles are in the end.
6
Make a change-unknown story using 6 and 10.
- Read the start and end quantities with a pause between them.
- Use a number line or counters to show the distance between quantities.
- Invite the child to say 'I know the start and end; I need the change.'
