In this activity, students identify multiples and factors and solve problems that involve finding highest common factors and lowest common multiples. Students will need a good recall of multiplication basic facts in order to be able to do these activities.

### Sixth grade Lesson Factors and Multiples in the Real World

Which squares could you choose to cover with your counter? Which throws of the dice would give you a multiple of 5? Which other products can you throw more than one way using the game dice?

Factor-multiple Chains Age 7 to 11 Challenge Level: Can you see how these factor-multiple chains work? Find the chain which contains the smallest possible numbers. I want students thinking: To solve problems involving events happening in cycles, it may be helpful to find multiples and common multiples.

As students are workingI circulate around the room and check in with each pair.

## Divisibility

I am looking for: Are students explaining their thinking to their partner? Are students writing their work in the work space? Are students using factors and multiples to help them solve? Are students annotating the problem? Are students answering in full sentences?
