Print the certificates to award students once they have mastered each set of tables. In my room I have laminated the base page for each student. They each have their own whiteboard marker and 1/4 of a dish wash sponge. I place the numbers 1-12 randomly on the board and they copy into the left column. In the middle column they write the table they are trying to master. They have 60
seconds to complete the tables. I mark, and circle pass/practise. If they achieve the table they need to complete it a second time in 30 seconds to achieve the mastery certificate.
