This is a “Tarsia: Convince Me” activity on BIDMAS / Order of Operations

Unlike standard Tarsia activities, here you only need to print out the solution (included on the PowerPoint), and students must:

1. Find (at least) 5 incorrectly matched up elements, convince you that each one is incorrect explaining the mistake that has been made, and then decide what the answer should have been

2. Replace the ? with the correct answer

3. Come up with a question to replace ?? that could give the answer. A selection of these questions can then be given to other students to use as a rich, challenging, pupil-created homework.
