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.
Keywords
Division - Division means splitting into equal parts or groups.
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.
Give pupils a chance to explore number rods prior to the lesson so that pupils can focus on mathematical learning. Pupils can work out the number of 5 cm and 10 cm lengths in lengths up to 100 cm, perhaps noticing the relationship between them (there are two 5cm lengths in every 10cm).
