This video is a math teacher’s dream.

So many possible questions, including
*How long will it take to mow the whole lawn?** *But before you can answer that sort of question, you’d better
make sure you’ve got the set-up right.

That’s where
Lawnmower Math comes in. We set the virtual stake nice and deep in the calculatorâ€™s ground.
You decide how big that stake should be. What math do you need to know in
order to mow both *completely* and *efficiently*?

Students estimate.

Then they calculate, and then generalize. Building algebraic understanding on
top of numerical relationships is what this summertime, lemonade-sipping, lawn
mowing version of
*Central Park* is
all about.

It’s challenging and beautifulâ€”you and your Algebra, Precalculus, and Calculus students should give it a whirl.
