- Bar charts
What we want children to know
- Understand the vocabulary of total, altogether, more, less and difference
- Draw pictograms where the symbols represent 2, 5 or 10 items
- Interpret part of a symbol, for example, half of a symbol representation 10 will represent 5
- Explore horizontal and vertical pictograms

- Construct a pictogram and choose an appropriate key
- Interpret tally charts in order to construct bar charts
- Interpret information from bar charts and answer questions relating to the data
- Apply addition and subtraction skills to answer questions accurately
What skills we want children to develop
Use knowledge to solve reasoning and problem solving questions such as:
Is this true or false? Convince me:
Make up your own ‘true or false’ statement about the bar chart.
Similarities and Differences:
Pupils identify similarities and differences between different representations and explain them to each other.
Create a question:
Pupils ask (and answer) questions about different statistical representations using key vocabulary.
- How would you show 6, 11 and 18 as a tally?
- If a symbol represents 2, how can you show 1 on a pictogram? How can you show 5?
- What does a pictogram show? What doesn’t it show?
- Is it always possible to use half a symbol? Why?
- Which scale should we use? How can you decide?
- Where do we need to use tables in real life?
