​How to do the Quizizz Lesson

​This lesson is self guided. As you click through the slides using the arrow keys, it will reveal the next part of the lesson. This Quizizz will contain guided examples, just like we would do in class. Except, you will be doing them on your own.

​

​There will also be examples for you to do at the end as a check-in. The results of the Quizizz will be sent to me so I can see how you did!

Now, you will try some on your own!

​The next slides will present a few questions for you to try. If you need to review the notes on the previous slides, please do so before continuing.

​

​When you are ready, continue to the next slide.
