Classroom use in Courses and Topics:

Algebra: Functions / Relations, Linear Equations, Analyzing Linear Data, Polynomials, Factoring Polynomials, Quadratic Equations, Graphing Quadratics, Quadratic Systems
Algebra II: Quadratic Equations, Functions / Relations, Parent Functions, Transformations of functions, Polynomials, Exponential Functions

Duration of classroom use:

Multiple Weeks

What did students learn?

An excellent realization of the connection between distance and time, velocity and time, acceleration and time. Fabulous intro to graphing.

What did students do with the resource?

"Walk it" Students get an opportunity to walk the given graph on the screen. Tremendous class discussions on how to generate particular graphs. When done properly students can gain an initial idea of the visualization of functions.

How hard was it for students to use?

Easy

Other classroom comments:

Ball drop lab that is described in the text is an open-ended look at quadratics, exponentials and even logistics curve.

Appropriate for:

introduction to a concept, advanced investigations

Other Comments:

I have used the CBR as an intro to an Algebra I class before the graphing gets hot and heavy. I have also used it with an Algebra II/Pre Calculus class in considering the relative drop in a ball over several bounces.

What math does one need to know to use the resource?

Depending on the activity chosen in the book none.

What hardware expertise does one need to learn to use the resource?

CBR and calculator use.

What extra things must be done to make it work?

Slow the process down for Algebra I students and have them communicate as a class or in groups what variables are being represented prior to the activity. This will facilitate the "matching process" if everyone is clear on the interdependence of the variables.

How hard was it for you to learn?

Very Easy

Explanation:

The activity's outlined can be fairly straightforward or rich in depth. As you work through the various labs you and your students will gain proficiency with the technology.

Ability to meet my goals:

Effective
