Collaborative Work
1. Look at each card and indicate which
calculations are correct and which are
incorrect.
2. Work out what the student is doing that is
wrong. They are using the same method for
each calculation.
3. Explain why the student’s method does not
give the correct answer.
4. Do the wrong calculations correctly.
