Alg 2 - Finding Zeros and Points of Intersection on a Graphing Calculator

This activity is broken into seven parts. Part I: Guides students in noticing that the trace key may not locate the x-intercepts (zeros) but shows them that there is another way x-intercepts can be found. Part II: Illustrates that there are algebraic techniques that can be incorporated in finding zeros.Part III: Shows student show to use a built-in feature to find x-intercepts or zeros.Part IV: Investigates how tables can be used to find x-intercepts and/or points of intersection. Part V: Chall

Trigonometric Functions on the Graphing Calculator - An Exploration

This activity sheet engages students in studying the general trigonometric equation y = a + b cos(cx) and making statements about the period, amplitude, y-intercept, and x-intercepts. After developing ideas with the cosine function, students make conjectures about similar sine graphs and then make a prediction of how a cosine graph would be changed to produce a particular graph.

Alg 1 - Exponential Functions y = k(b^x)

Through this hands-on activity students will use the graphing calculator to study the affects of K and B on the equation y = k(b^x). Students will study exponential functions graphically and numerically.In my store there is an identical activity that uses the function y = a(b^x) rather than y=k(b^x).

Calculus - Continuity

This activity engages the students in understanding the three parts of the definition for a continuous function at a point by asking a series of questions about several functions.You also might be interested in the Activity Sheet on Continuity and the Intermediate Value Theorem that is available in my store. A recent buyer said "Thank you for providing this resource. I appreciate your time and investment in creating a helpful resource."

Alg 2 - MAXIMIZING THE VOLUME OF AN OPEN BOX

This activity guides students through an activity where they build rectangular boxes: Working in groups, students cut a 1x1 centimeter squares from each corner of a 20x22 centimeter sheet of paper and fold the paper to form an open box. Continue to cut 2x2, 3x3,4x4, 5x5, 6x6, ... 10x10 centimeter squares from other sheets of 20x22 centimeter sheets of paper. Each time they form the open box. Each person selects a box and calculates the length, width, height and volume of the box and they recor

Alg 1 - Exponential Functions y = a(b^x)

This is a modification of another product available in my store. Instead of using the equation with constants of k and b, this equation uses the standard a and b. Through this hands-on activity students will use the graphing calculator to study the affects of a and b on the equation y = a(b^x). Students will study exponential functions graphically and numerically. In my store there is an identical activity that uses the function y=k(b^x) rather than y = a(b^x).
