Your teacher can set you a goal of earning 1, 2, 3 or 4 stamps per week.
You can earn one stamp per day when you complete a MemRi quiz.
If you earn all the stamps for the week, you achieve your goal for the week.
Be careful! If your goal is 3 stamps per week but you only start on Saturday, you won't achieve your goal. You can only earn one stamp per day.
The purpose of MemRi is to help you remember the maths skills you've learned and the best way to do that is to practice them a little and often.
We recommend that teachers reward students who consistently achieve or exceed their weekly MemRi goals.
