## Lesson details

### Key learning points

1. Knowledge of decimal place value can help to read the scale of a graph.
2. Knowledge of decimal place value can help to read a measuring scale.

### Common misconception

Pupils count the interval markers to find how many parts the whole has been divided into.

Identify clearly which whole you are dividing and link the bar model to the numberline to show how the intervals reveal the number of parts.

### Keywords

• Multiple - A multiple is the result of multiplying a number by an integer.

• Common - Something is common when it is frequently used or it occurs regularly.

• Partition - The act of breaking an object or value down into smaller parts.

• Interval - The space between two values or points.

Encourage pupils to move away from counting up in multiples of each common partition, to counting on from multiples that make a whole. For example: to find 6 lots of 0.25, count on 2 lots of 0.25 from 1 as this is 4 lots of 0.25.
