Lesson details
Key learning points
- You can explain and represent multiplication when a group contains zero or one items.
- The group size can be 1 and the number of groups can be 1

Keywords
Zero - Zero is the number that represents no amount or objects. When we add zero to a number, the result is just the number, unchanged.

Common misconception
Children may struggle to comprehend groups of zero. For example children may see four empty plates as four groups of one.
Use a context where the number of groups is still visible when the group size is zero. Remember to make the distinction as to what is representing zero. Use the familiar stem sentences There are ___ groups of ___.
