Teacher will use the TINavigator™ to submit graphs of absolute value functions and students will attempt to match the teacher graphs while logged on to TINavigator. Several questions are suggested to help students analyze the functions and internalize their understanding.

The activity uses Cabri Jr. and TINavigator™ to explore the angle between the branches of an absolute value function. By the end of the activity, absolute value functions will be connected to trigonometry. This activity can be used in an algebra 2/precalculus course where students are already familiar with absolute value and trigonometric functions. It can also be used to introduce students to the connections between functions in an algebra 1 or geometry course.

The students will construct several rectangles with different dimensions, all having the same perimeter. The area of each rectangle is then computed and plotted against the width of each rectangle. The students will discover that the area is a quadratic function of the width. They will also discover that the rectangles attain a maximum area.

Students use formulas to find the differences of the consecutive terms, plot a scatter plot of each sequence, and determine that sequences with common differences (called arithmetic sequences) have scatter plots whose points form a straight line.

This activity can be used alone in math class or as an interdisciplinary unit. The activity can also be used as a unit or as a warmup or daily lesson for 80 days.
Students will 'visit' locations around the world much like in the book "Around the World in 80 Days." In TINavigator Activity Center, they will use their knowledge of mathematics and functions to submit equations to fit a line, curve, etc.. in the picture.

Students relate the graph of a rational function to the graphs of the polynomial functions of its numerator and denominator. Students graph these polynomials one at a time and identify their yintercepts and zeros. Using the handheld's manual manipulation functions, students can manipulate the graphs of the numerator and denominator functions and see the effect on the rational function.
