Solve addition problems to 20 by counting all the objects in their head.
Solve subtraction problems from 20 by counting all the objects in their head.
Instantly recognise patterns to 10 including doubles.
Number Framework Stage 3
- Tens Frames
- Counters
Using Materials
Problem: Brita has 10 rabbits and she gives 2 rabbits to her friend. How many rabbits does Brita now have?
Write 10 - 2 on the board. The students put 10 counters on blank tens frames and
remove 2. Without counting encourage students to recognise instantly that there are 8
counters left. Record the answer on the board.
Examples. Word stories and recording for: 10 - 3, 4 + 5, 10 - 6, 2 + 5, 2 + ? = 7
Using Imaging
Shielding: Problem: Jonah has 5 jelly beans and he gets 3 more jelly beans from a
friend. How many jelly beans does Jonah now have?
Write 5 + 3 on the board. Out of the students. sight build 5 on an empty tens frame.
Ask students to describe how you have built it. Drawing pictures in the air may help.
Add 3 and ask how you built it. Ask how many counters there are altogether. If
necessary fold back to Using Materials by showing the students the hidden counters.
Record 5 + 3 = 8 on the board.
Examples. Word stories and recording for: 4 + 5, 10 – 3, 6 - 5, 5 + 2, 10 – 8, 2 + ? = 7 ….
Imaging Only
Problem: What is the missing number: 3 = - 8 ?
Write 3 +? = 8 on the board. The students think about the solutions without seeing
the tens frames. Record the answer on the board.
Examples. Word stories and recording for: 9 - ? = 4, 8 - ? = 5, 2 + ? = 10, 2 + ? = 5, 1 + ? = 10.
