Reply To: Lesson 2-2 Question

[Nicolle Ristow]

The problem I am working with is How much water is wasted from a dripping faucet? Is it enough to fill a glass, sink, or tub?

I use this problem with my College Algebra class to introduce the 5 steps of math modeling that are used in the class. This problem would be completed in the first or second week of school.

Withhold information:

– how fast is the drip happening

-the dimension of a glass, sink, or tub

– size of the drip

Anticipation:

This is the part that I am struggling with because I feel this will come from the notice and wonder discussion. I would ask the students what information we would need to know to answer this questions and talk about how we could get this information. In this part I might also that about what assumptions we are making to help us solve this problem

Notice and Wonder:

Show a video of a dripping faucet.

Estimation:

Estimation the amount of water that is wasted. Estimate which container this amount of water fill: glass, sink, or tub.
