Teaching Multiplying and Dividing Rationals: Assessments

*Also Known As: My First #Shorts Videos on YouTube

I always laugh when I tell someone I have a YouTube channel.

That’s because I’m the least likely person you’ll ever see on there.😆

But I think teaching roomfuls of teenagers seasons us to the point that creating a video is not as intimidating as it is to most people.

If you can stand up and teach 35 sixteen year olds, you can pretty much do anything you put your mind to!

Okay, enough of all that…

Start With Rationals That Have Already Been Factored

Google Forms assessments are a great way to do this.

Watch the video to see the mini assessment I created to check the following:

Do students understand that they need to keep-flip-change when dividing rationals?
Do students understand what terms can and cannot be factored out (also called canceled out or divided out) when multiplying and dividing rationsals?

LOL, the thumbnails YouTube picked are so weird.😂

These are problems where no factoring is required.

Watch the video for examples of test questions that require students to use exponent rules correctly.

For the main event: Multiply or divide and then simplify rational expressions.

Factoring is required for each of these problems.

There’s a lot to the Rationals Unit, so don’t stop here.

I have an entire unit on assessing Rationals that’s typically taught in Algebra 2. Check it out.
