Topic 1: Rotational and Bilateral Symmetry, Grades 7-8

(classroom idea 4A, CM, p.51)

Have students examine logos of businesses for rotational and bilateral symmetry. Then, using the computer, design a logo for an area business that is an example of rotational or bilateral symmetry.



Topic 2. Exploring different video rental plans (Math A)

Classroom idea 7C, p. 69 of the Course Materials


Two video rental clubs offer two different rental fee plans:

Club A charges $12 for membership and $2 for each rented video.

Club B has a $3 membership fee and charges $3 for each rented video.

For what number of video rentals is it less expensive to belong to club A?

 Topic 3: Quadratic Functions, with application to Projectile Motion, Math B

Classroom idea 2A, CM, p.88, Math B


Physicists tell us that the altitude h in feet of a projectile T seconds after

firing is h = -16t^2 + vt + h where v is the upward component of its initial

velocity in feet per second and h is the altitude in feet from which it is

fired. A rocket is launched from a hilltop 2400 feet above the desert with an

initial upward velocity of 400 feet per second. When will it land on the

desert? Discuss what the discriminant can tell you about the solution to this

problem. Then use the quadratic equation to find the solution and explain your
