How it works
Find the whole and the parts in the story.
If the whole is missing, add the parts.
If a part is missing, take the other part from the whole.
Worked examples
Put together
- Ben has 4 apples in the bowl. He has 2 apples in the bag. How many apples does Ben have in all?
- Draw the two parts.
- The whole is missing, so add.
- So the answer is 6.
Find the start
- Ana had some fish. She gave 18 away. Now she has 2 fish. How many fish did Ana have at the start?
- Ana gave 18 away and has 2 left.
- She had the 18 and the 2 together: add them.
- So the answer is 20.
