Achievement Objective: NA1-1: Use a range of counting, grouping, and equal-sharing strategies with whole numbers and fractions.
AO elaboration and other teaching resources
Achievement Objective: NA1-3: Know groupings with five, within ten, and with ten.
AO elaboration and other teaching resources

Specific Learning Outcomes: 

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.

Description of mathematics: 

Number Framework Stage 3

Required Resource Materials: 
Counters.
Ten Frames (Material Master 4-6)
Activity: 

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.
