There are many ways you can get students to communicate their understanding in math. Here are three common prompts with examples. Ideally, students should solve the problem independently first then compare their answer with the exemplars shown below.

- show your work.
- explain your thinking
- justify your answer

Each prompts asks for different information so students (and teachers) need to know the difference. At the end of the day, you want students to do whatever they can to convince the reader they understand the problem or concept.
Please note that these exemplars uses EQAO samples (Level 3 & 4). If you're looking for more information about EQAO, you can visit the EQAO Resources page.
