YES!
This is the tangible stuff we want our students to have in mind when first learning about new math concepts. Sure, we could teach volume as the area of the base multiplied by the height. But what happens on the exam one week later: the formula B x h is as fresh as week old milk on the counter.
And that’s what we might do as teachers — leave things out on the counter for our students, only for them to spoil. Ok, maybe I’ve taken the lumpy-milk-in-my cereal-this-morning analogy too far, but how many times have you just delivered a lesson and expected its contents to stay fresh in a student’s mind? What have you done to really make it stick?
Great content, such as the following video, is short (in viewing length), concise (in language), and relevant.
And I’m going to keep my blog post tonight just that.
Enjoy.
