Lesson details
Key learning points
- The amount in a group can tell you whether to skip count in twos, fives or tens.
- The pattern of the ones digits can help you recognise groups of two, five or ten.
- It is more efficient to count in groups of a larger size.
- When there are an equal number of groups, the larger the size of each group, the greater the amount altogether.
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.
