I thought it was a great intro to connect something they already know with something new.

Agreed. I always say that it is the algebra skills that kill students more than the calculus!

It had never occurred to me to have the students graph the function and tangent in the calculator to double check--great tip!

Some students even have trouble evaluating numbers raised to 2/3 power.

I love incorporating these videos into class because they're well developed and explain the topics very well. I also like showing the students that they can use them to catch up if they miss class or are confused about a topic.

My students tend to have trouble going back to Algebra I in calculus. They think tangent line problems have to be difficult. It takes a long time to convince them that they need to find a point and a slope and write the equation of a line!

I often use these video to intro. a topic and then just have students work examples in groups on the whiteboard!

Students often make mistakes in my class when I have them approximate a value before the point of tangency, the always miss negatives.

Just found a Desmos Activity for this that I LOVE! I am definitely using it this year for class and will share during the share out portion of the course!

This video would probably only enhance the students understanding of the material. I think the more they engage or see material like this the better!

I like to use some questions from a Desmos activity. It's great and allows the students to really see what's going on.

It's writing out the equations. Students typically forget to find a point and a slope.

Students tend to get intimidated by the name "tangent line approximation" when they just need to be refreshed on the point-slope form of a linear equation.

I might prefer to "recreate" the video live instead. However, this might be good while I am checking homework.

Some of my students do not like writing out the sentences. They just want to solve.

I would not have the students watch the videos in class. Although 10 minutes or so is not that long, I would not want to lose those 10 minutes. I do like the Khan Academy and the AP classroom videos for this lesson, and I like that the students could then answer some AP questions or they could answer the Khan Academy questions at the end to check their understanding. I would assign this as intro homework.

I may have students watch videos in class, but I would be more likely to have them watch outside of class and then discuss during class tine.

I usually see students getting confused in a way that leads to them mixing up the independent value they are supposed to use to write the equation with the independent value for which they are making the approximation.

I love using videos to introduce topics, but I'd probably just show part of this one to save class time.

I like the idea of using the videos as something students would watch at home before the lesson, or as part of their practice to help them. My students have said they really don't like watching videos in class, they would rather me explain things.
