Week 6 Statistics

National curriculum content

  • Interpret and present data using bar charts, pictograms and tables
  • Solve one-step and two-step questions [for example, ‘How many more?’ and ‘How many fewer’] using information presented in scaled bar charts and pictograms and tables


Lesson objectives

  1. Make tally charts
  2. Draw pictograms
  3. Interpret pictograms
  4. Bar charts
  5. Tables


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
  • Read and interpret information in order to answer questions about the data
  • 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.


Mathematical talk

  • 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?
