Be Direct - Oil Spills on Land

Direct variation is taught using a simulated oil spill, using toilet paper tissues (to represent land) and drops of vegetable oil (to simulate oil). 

Bigger and Smaller - Exponent Rules

Use a scene from Alice in Wonderland to introduce negative exponents and the rules for dividing powers. 

Bouncing Ball - Function Families

Explore quadratic functions by using a motion detector known as a Calculator Based Ranger (CBR) to examine the heights of the different bounces of a ball.

Cups and Chips - Solving Linear Equations Using Manipulatives

Manipulatives visually represent the steps taken to obtain the solution to an algebraic equation.

Curses and Re-Curses! It's Happening Again

The class learns about basic recursion by exploring patterns in the data they generate from two simple probability-based experiments.

Hassan's Pictures - Linear Programming and Profit Lines

Find the feasible region in a linear programming problem, graph a family of profit lines and find the optimum point.

Hot Dog Sales - Solving Linear Equations and Inequalities

Provides an introduction to solving equations and inequalities numerically (using a table), graphically, and algebraically.

Left Hand, Right Hand - Solving Systems of Equations

Compare the speed at which you write with your left hand to the speed at which you write with your right hand In order to understand the three different types of possible solutions to a system of two equations with two unknowns.

Mathematical Modeling, Circular Movement and Transmission Ratios

Examine the difference in the number of revolutions for each of two gears in a model, in order to undertand the significance of the radii of the gears.

Miles of Tiles - The Pool Border Problem

Algebraic notation and variables are used to recognize patterns and represent situations.

Overrun by Skeeters - Exponential Growth

This introduction to exponential functions considers the world population since 1650. In a simulation, the population grows at a random yet predictable rate.

The Phone Bill Problem - Linear Functions

Write an equation of a linear function when given a set of data. Interpret the meaning of the slope and y-intercept and then use the equation to find other values of x and y. 

Skeeter Populations and Exponential Growth

Exponential functions are used to represent population growth.

Up, Down, Right, Left - Function Families

Study quadratic functions by examining the family of functions described by = a (x - h)2 + k. 

Very Varied - Inverse Variation

Compare the heights of a fixed amount of water poured into cylindrical containers of different sizes to the area of the containers' bases.

The X Factor - Trinomials and Algebra Tiles

Factor trinomial expressions of the formx2 + bx + c. Use algebra tiles to identify the binomial factors and the graphing calculator to verify the result.
