In this meeting hosted at 3rd Avenue VFW by teachers at MDC Brooklyn, we continued recent explorations into multiplication and factors. In this meeting, we looked at divisibility rules. After a pair/share and introductions, I asked the group to look at multiples of 9 and share what patterns they noticed. We shared in small groups then talked about a few things people noticed.

## Divisibility Exploration

In this meeting we looked at the divisibility rules for 2, 3, 4, 5, 6, 8, 9 and 10 and tried writing our own rules for larger numbers.
