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