Counting, Multiplication, Common Multiples
Key Stage: 1 ★
If two of you count from 1 to 20, one clapping more loudly on the numbers in the two times table, the other on multiples of five, what will you hear?
This activity is a lovely practical way for children to investigate common multiples and to gain familiarity with their tables. It also allows children to make and justify conjectures.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.

An excellent way to help the children to learn and think about the 2 times table. Can be linked with 5 and 10 times table so children can identify relationships between tables.
