Peter can mow the lawn in 40 minutes and John can mow the lawn in 60 minutes. How long will it take for them to mow the lawn together?

In these lessons, we will learn

- how to solve work problems that involve two persons
- how to solve work problems that involve more than two persons
- how to solve work problems that involve pipes filling up a tank

This formula can be extended for more than two persons. It can also be used in problems that involve pipes filling up a tank.

Example 1:

Peter can mow the lawn in 40 minutes and John can mow the lawn in 60 minutes. How long will it take for them to mow the lawn together?

The new Common Core standards for mathematics demand that students (and teachers!) exhibit deeper conceptual understanding. That’s music to the ears of education professor John Tapper, who says we’ve overemphasized teaching procedures and getting right answers. In his new book, Solving for Why , he makes a powerful case for moving beyond right and wrong and exploring what students understand, where they are struggling, and most important, why they are struggling.

We talked with Tapper about concrete-representational-abstract assessments, or CRA, a tool that does just that. It’s easy to do, and it provides a sophisticated portrait of kids’ models for mathematical concepts. That ties in with the Core, and with Tapper’s call for teachers to focus on the learner. As he puts it: “Before I do anything, I need to know what’s going on in this student’s head.”

A perfect square trinomial is a polynomial that you get by squaring a binomial. (binomials are things like ''''''''x + 3'''''''' or ''''''''x − 5'''''''')

Now, you might be saying to yourself that $$ x^2 + 10x = 24 $$ could easily be solved without any fancy new methods (You could easily factor it, for instance.)

And, this of course is true. However, it turns out there are times when completing the square comes in very handy and will help you do a variety of things including convert the equations of circles, hyperbolas, ellipses into forms that make it much easier to work with these shapes.
