Lesson Details

Key learning points

Skip counting can be used to calculate the number of equal groups in a division story.
You can use skip counting to work out the number of shorter lengths that are equal to a longer length.
50 cm divided into groups of 10 cm lengths is equal to 5; 50 cm ÷ 10 cm = 5
There are 5 groups of 10 cm lengths in 50 cm.

Common misconception

Pupils may assume that any number is equal to an exact number of number rods.

There is a focus on multiples of numbers, especially multiples of 2, 5 and 10 in the lesson, but there is an example of a division calculation with a remainder in the first cycle to help pupils become familiar with this concept.
