Wait until your table partner is done, and then assess his/her formative on MATH PRACTICES! Here are the criteria:
E - multiple representation/ check answer
4 steps for complete solution (4/4) ←- i like the “out of 4” criteria”
1 - copy question/list key information from question
2 - diagram/ assumed formulas
3 - step by step working out
4 - circled answer with correct units
M - 4 steps for complete solution (3 of 4 steps without errors)
1 - copy question/list key information from question
2 - diagram
3 - step by step working out
4 - circled answer with correct units
P - 4 steps for complete solution (2 of 4 steps without errors)
1 - copy question/list key information from question
2 - diagram
3 - step by step working out
