Lesson details

Key learning points

  1. Skip counting can be used to calculate the number of equal groups in a division story.
  2. You can use skip counting to work out the number of shorter lengths that are equal to a longer length.
  3. 50 cm divided into groups of 10 cm lengths is equal to 5; 50 cm ÷ 10 cm = 5
  4. 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).
