Common misconception
Children may not be sure which unit to count in. They may confuse the size of the group with the number of groups, for example saying 5 groups of 2 instead of 2 groups of 5.
Encourage children to draw a ring around each group as they count the groups and display and use the stem sentence to help them describe this.
