Common Core requires students to know many strategies for solving problems and to be able to identify a most-efficient strategy.
Use this tool for math activities and as part of your ongoing Formative Assessment Cycle as a pre-assessment or exit ticket. The uses are endless! Write a problem in the middle or have students write one in. Students represent the work 4 different ways. Bonus, have students put a star in the box that they believe is the most efficient strategy.
Alternative: Have students show 4 representations and write a word problem on the back!
Other uses: vocabulary development, expert groups, "huddle", and so many more!
