I can read the scales of graphs and measures using knowledge of the composition of 10,000 and 100,000

Lesson details

Key learning points

  1. Measuring scales can be interpreted by counting in steps of 1,000, 2,000, 2,500 and 5,000
  2. Measuring scales can be interpreted by counting in steps of 10,000, 20,000, 25,00 and 50,000
  3. Graph scales can be read and interpreted by counting in multiples of 1,000 and 10,000

Keywords

  • Multiple - A multiple is the result of multiplying a number by an integer (not by a fraction).

  • Gridlines - A gridline is a horizontal or vertical line that helps organise data on a graph or graph.

Common misconception

Pupils struggle to create axis for their graphs that have equal intervals.

You could spend some time with pupils simply practising drawing each axis. Ensure pupils do not draw a line and then try to divide into equal intervals. Instead encourage marking the intervals as the line is drawn.

Whilst we can recognise that graphs with more gridlines may help us to be more accurate with our estimations, encourage pupils to understand that it is important that they recognise data where more gridlines is not necessarily important to register accuracy.
