Common misconception
Pupils may be confuse the 'size of group' and the 'number of groups' in a division equation.
Label each part of a division equation e.g. 12 divided into groups of 2 is equal to 6 There are 12 __________ altogether. They have been divided into groups of 2 / there are 2 __________ in each group. There are 6 groups of __________.
Pupils will need access to manipulatives that they can group (e.g. cubes or counters), especially in the first cycle of this lesson. They can use large bar models to help support their thinking, arranging the counters on these to help them see the size of each equal group and number of groups.
