What is the Model Method?

5 units = 60
1 units = 60 : 5 = 12
8 units = 8 x 12 = 80 + 16 = 96
There are 96 people at the party.
Number of women
Number of men
Number of children

Model Method
In Lower Primary

Jack
Kyla
3 units = $300
1 units = $300 : 3 = $100
Kyla gets $100.

Larry
Maria
4 units = $300
1 units = $300 : 4 = $75
3 units = 3 x $75 = $300 - $75 = $225
Maria gets $225.

What if the larger number is 58?
1st Number
2nd Number
Then the smaller number is 58 – 12 = 46.
12
What if the sum of the numbers is 58?
58 – 12 = 46
46 : 2 = 23
Then the smaller number is 23 and the larger number is 23 + 12 = 35.
58 + 12 = 70
The larger number is 70.

What if the total number of boys and girls is 58?

58 – 12 = 46
46 : 2 = 23
Peter
Natalia
12
Peter’s bag weighs 23 kg.
Natalia’s bag weighs 23 kg + 12 kg = 35 kg.

Strategies
Who is in the story? What is it about?
Read a sentence. Do something.
Leave out numbers in reading a sentence.
Are you sure? Is it easy?
Do more mental computations.
Can you explain this step? Maybe other people cannot understand it.

Basic Models include Part-Whole Model, Change Model and Comparison Model

Mathematics to develop visualization through bar models, number sense through mental calculation, and ability to manage information through word problems.

Parents coaching children are providing the ‘voice’ that eventually becomes the children’s own thinking.
