Fascinating Fact:

How many fewer. If blue hats are 7 and red hats are 10, then 10 − 7 = 3 fewer blue hats.

In KS1 Maths, pupils read categorical data in tallies, pictograms, tables, and simple bar charts. They compare groups, find the total, and work out the difference using addition or subtraction.

  • Category: A group or type in the chart, like apples, bananas, or grapes.
  • Compare: Look at two categories to see which has more, fewer, or the same.
  • Difference: How many more or fewer. Find it by subtracting one amount from another.

Warm up with a quick activity: try the Numeracy Game before you start the quiz.

What does “how many fewer” mean in KS1 data questions?

“How many fewer” asks for the difference between two groups. Subtract the smaller number from the larger, for example 10 − 7 = 3 fewer.

How do I compare two bars in a bar chart?

Read each bar’s value from the scale, then decide which is bigger. To find the difference, subtract one value from the other.

What is categorical data for KS1?

Categorical data sorts things into groups, like hat colours or pet types. Charts show how many are in each group.
