3 Math Resources To Give Your Substitute Teacher

Posted 08/19/2022 by Mark Watson

There’s no need to fret when you’re away from class. We have hundreds of free math lessons and activities, including this huge collection of video resources, to give your substitute teacher while you’re gone. Whether you’ll be out for just a day or a bit longer, these math videos will keep students learning and on track with your lesson plans. A win for you, your students and your sub.

Check out these three featured video resources for your substitute teacher to use when you’re away





1. Families of Functions

Family of Functions

If your students are learning how to graph parent functions, TI’s Families of Functions is the go-to video resource for your substitute teacher. You can simply pick out one or more relevant topics for your students to watch and let the learning begin.

Families of Functions features a full library of learning modules for each function family, first starting with linear relations then ranging from quadratics to exponentials and more. From linear relations to quadratics, exponentials and more, each module includes videos that provide a step-by-step explanation on how to graph the main parent function, as well as a series of additional videos that teach students how to apply various transformations and graphing exercises for students to practice what they learn.

2. Smart Space

Smart Space

Smart Space features full-length math lessons, which can be particularly useful for teachers planning on being away from their students for a week or more. This video library goes over topics covered in middle and high school math subjects, including geometry and algebra I and II.

An introduction to ratios for middle school classes.

Most of the Smart Space videos range from 15 to 25 minutes in length. What’s more, the lessons effectively build on top of one another, so your sub should have no problem keeping students on track with your lesson plans for extended periods of time. For instance, the Smart Space geometry lessons provide an overview of several topics in a sequence, starting with transformations and followed by congruence, similarity, then distance, right triangles and circles.
