Data Detective: Compare Two Categories

Name:                              
Date:              

Today I am practising: finding how many more or fewer items one category has

1

A chart shows 7 circle votes and 4 square votes. How many more circles?

2

Draw lines to pair 5 red and 3 blue counters. How many red are extra?

3

Complete 8 - 6 = __ using a graph.

4

Write a fewer sentence about 2 cats and 5 dogs.

5

Choose the two closest categories in a three-row graph.

6

Make two categories that differ by 3 and show the difference.

Grown-up guide
  1. Line up items from a shared starting edge before subtracting.
  2. Read more and fewer comparison sentences both ways.
  3. Ask which two category totals are being compared before calculation.
