Adding and taking away: I can add, take away and find pairs for 10.

1. Here are 4 ducks.

   Here are 3 more ducks.

   4 + 3 = 7

   Picture: Two groups of ducks: 4 and 3. The groups are pushed together and counted. 7 ducks altogether.

2. Your turn: 3 fish and 2 more fish. How many fish in all?

   Picture: Two groups of fish: 3 and 2.

   Choose one:

   • 4
   • 5
   • 6

   Answer

   The answer: 5

   1, 2, 3, 4, 5. 3 + 2 = 5

   Picture: Two groups of fish: 3 and 2. The groups are pushed together and counted. 5 fish altogether.

3. What is 12 + 3? Start on 12.

   Count on 3: 13, 14, 15.

   12 + 3 = 15

   Picture: A number line from 10 to 20. A dot at 12 labelled "start". The kangaroo hops from 12 to 13, then to 14, then to 15.
