Mathematics

CURRICULUM FOCUS

We are learning to use subtraction strategies. 

I can make the whole and take away the part. (10 - 5, make 10 with materials or draw, physically take away the part)

I can use count back strategy. 

 (8 -  3 = say 8, draw lines, circles or numbers to show how many you count back.) 

I can use partition to count back easily. 

 for example, 8 and 6 is the same as 8 and 2 and 4

I can check my answer with a second strategy. 

VOCABULARY

Subtraction: minus, takeaway, left over

Represent a problem: using drawings, physical and virtual materials, and number combinations within 10 to add and subtract collections to 20

Count back: 8 - 3 = 8 , 7, 6, 5

Partitioning: 7+5=7+3+2=10+2=12 

ACTIVITIES YOU CAN DO AT HOME TO SUPPORT YOUR CHILD'S LEARNING

To help students with their subtraction strategies, pose open ended questions such as: 

Students can then solve this problem and check their answer with a second strategy.
