I created this as a quiz to assess my students' proficiency with divisibility rules. It is in a chart form, where students write an X in each box for the rules that apply to each number. This focuses on the divisibility rules for 2, 3, 4, 5, 6, 9, and 10.
There is also a section underneath the chart where students must write the rule for each of the above numbers.
This could also be used as a homework assignment, parter activity, small group, etc.
