# Let’s Learn Mathematics (Primary Level) — Model Method 3

### Start here

Continuation from Let’s Learn Mathematics (Primary Level) — Model Method 2

2. Comparison model

Comparison model is used to compare two or more items.

Example (a): Jenny has 6 dresses and 2 pairs of pants. How many more dresses than pants does she have?

6 – 2 = 4

She has 4 more dresses than pants.

Model for example 2(a)

Example (b): A pair of pants costs S\$35. A dress costs S\$ 10 more than a pair of pants. If Jenny buys 3 dresses and 2 pair of pants, how much does she need to pay?

The cost of a dress = 35 + 10

= 45

Total cost = (3 x 45) + (2 x 35)

= 135 + 70

= 205

She needs to pay S\$ 205.

Model for example 2(b)

Notes:

1. If you cannot draw nicely, cannot draw to scale, etc, no need to worry, this is Mathematics, not arts. Remember, it is the understanding of the questions that is the most important.

2. There are different types of Mathematics questions but there is only one model method. Do more Mathematics questions to practise on the model method.

3. Be flexible about the models, you draw the model according to the question, not to what you remember from previous question(s).
