• Solving problems using information presented in picture graphs.

What will we learn today?

Data AnalysisPicture graphs

We have learnt how to read and study graphs in Primary One.Now, we are going to use this knowledge to help us solve problems.

Here’s some important points to note. Whenever you see a graph, remember to look at the headings and values.

Stamps Collection


Tom

e.g. John has 3 stamps.

How many stamps do May and Tom have altogether?

Let’s try this together.

5 + 3 = 8

5 3

Here’s another example.

The picture graph below shows the number of cans of juice sold from Monday to Friday in a coffee shop. Monday Tuesday Wednesda

yThursday Friday

Each star represent 2 cans of juice.

The picture graph below shows the number of cans of juice sold from Monday to Friday in a coffee shop.

The coffee shop sells 10 more cans of juice on ______ than on Monday.


10 cans is represented by 5 stars.So, we need to see which column has 5 more stars than Monday.


The coffee shop sells 10 more cans of juice on Thursday than on Monday.

Let’s apply what we’ve learnt.
