# Week 11 - 12 Statistics

National curriculum content

• Solve comparison, sum and difference problems using information presented in a line graph
• Complete, read and interpret information in tables, including timetables

Lesson objectives

1. Draw Line Graphs
2. Read and interpret line graphs
4. Two-Way Tables

What we want children to know

• Read a range of different graphs and tables including timetables
• Recognise which graph represents the given information in the best way
• Understand that our knowledge of graphs and tables can be transferred across the curriculum
• Use different strategies to interpret graphs and tables
• Use different strategies to complete the information in a table or timetable
• Compare the information provided in more than one line graphs in order to solve problems

What skills we want children to develop

Use knowledge to solve Reasoning and Problem Solving questions such as:

Interpret Charts:

Ilkeston Town Football Club sold the following number of season tickets:

• Boys – 3,597
• Girls – 4,582

Would you use a bar chart, table or pictogram to represent this data?

Explain why.

120 people were asked where they went on holiday during the summer months of last year.

Use this information to create a two-way table.

Two-Way Tables:

In June, 6 people went to Germany and 18 people went to Poland.

In July, 10 people went to Germany and 19 people went to Spain.

In August, 15 people went to Poland.

15 people went to Germany altogether.

39 people went to Spain altogether.

35 people went away in June.

43 people went on holiday in August.

Draw Line Graphs:

Here is a table of data.

 Time (min) 5 10 20 30 45 Distance (km) 12 35 42 68 84

Which intervals would be the most appropriate for the vertical axis of the line graph?

Mathematical Talk

• What is the same and what is different about the way in which the data is presented?
• What scale will you use for your own bar chart? Why?
• How is a line graph different to a bar chart?
• Which is the x and y axis? What do they represent?
• Where do we see examples of line graphs in real life?
• How can we estimate the value between intervals on a line graph? Does it matter if we are not perfectly accurate? Why?
• Why are column and row headings important in a table?
• Which column do I need to look in to find information?
