Last Man Standing: A Hands-On Activity to Introduce Exponential Functions
This hands-on activity helps students develop an understanding for how to use an exponential function (y=ab^x) to model different situations. This specific activity has students start with 100 squares that are "Alive" and they shake them and drop them every round and count how many squares survive each round. They will eventually develop an exponential function (y=100(0.50)^x) to model the number of squares left as a function of how many rounds have passed. Students will then graph their functio

Trig Identities and Proofs Worksheet
I use this worksheet in my Pre-Calculus classes to study (as a whole class) for the Trig Proof quiz. In my class, this activity is called "Check Yo' Skills." Students need to
-Write the trig expression as the sine, cosine, or tangent of an angle
-Simplify the trig expression to a single term
-Prove the trigonometric identity
-Find the exact value of each trig expression using a sum or difference identity
-Find all solutions in the interval zero to 2*pi without using a calculator bu giving exact

Unit Circle Exploration
This is an activity to help students visually understand the patterns in the Unit Circle. They will cut out special right triangles and place these on a handout with pictures of the Unit Circle to help them find the missing angles and coordinates. Students will have a deeper understanding of patterns in the Unit Circle, which will help them remember it.

Graphs of Sine and Cosine
Students will match 10 graphs to 10 sine or cosine equations by finding the amplitude and period of each function. Students will then identify the amplitude and period of other sine and cosine functions, although they will not be required to graph.
Students can work as a group or by themselves. This is best used as a resource after students have learned how to find amplitude and period, and can also recognize the difference between sine and cosine graphs.

Modeling Tide Heights with Sine Functions Project
This is a project in which students do research on the heights of tides in different parts of the United States for different phases of the moon. Students will write the sine equations that best model these tides, and then graph their displays and answer questions pertaining to their functions and graphs. This project can be used as an in class assignment that is graded or just as an exploration activity. The grading rubric for the assignment is included.

Teaching Continuity to Pre AP Mathematics Students
This lesson is designed to introduce students to the concept that a function can be discontinuous. In Algebra I, students are exposed mostly to graphs of functions that are continuous everywhere. This lesson guides students through understanding three different types of discontinuities--point, jump and infinite. As students begin to investigate piece-wise defined, rational, logarithmic, and trigonometric functions, they need to understand what a graph can look like at x-values of discontinuit

Candy Lab: Solving Systems of Equations Using Matrices
This is a hands-on activity in which students will solve systems of three equations with three unknowns using matrices specifically RREF and Cramers rule. Students are given a sealed, opaque bag containing three different types of candies and the total quantity of candies the bag contains. Students are also given access to candies not in their bag to obtain an average weight of an individual candy. They then weigh the bag with the candy and an empty bag to obtain the weight of the total candies

PreCalculus Mathematics Formula Sheet
This is a formula sheet that I give to my students in Grade 11 Functions/PreCalculus.
Feel free to edit this sheet as you wish! I will usually review it at the beginning of each year to add or remove those formulas that may not be needed depending on the course I am teaching.
The formulas are given as such:
- Linear
- Quadratic
- Trig ratios, trig identities, sine and cosine law
- Arithmetic/Geometric sequences and series
- Compound interest and exponential growth and decay

Exploring Inverse Functions
This is an investigation that I use to introduce the big ideas of inverse functions. Students graph a linear function by making a table of values, interchange the x & y values in a table of values and graph the resulting function. When students fold the graph along the line y = x they can see that the two graphs are symmetric. The tactile activity is something that students will refer back to as they study more complicated inverse functions. After graphing the investigation leads the stu

Highly Effective Strategy for Teaching Right Triangles - FREEBIE!
Give students a transparent tool to help them label triangles!
Students often have trouble labeling parts (such as x, 2x, a, b, c, opposite, adjacent, hypotenuse, etc) of triangles for Special Triangles, Pythagorean Theorem, and Trigonometry. To help my students do this correctly, I give each student a labeled triangle printed on transparency film.

Properties of Logarithms Exploration - Matching Cards
Using a calculator, students figure out which expanded logarithmic expression is equivalent to each condensed expression. In doing so, students will discover how properties of logarithms work. There are 4 expanded expressions, but 6 condensed expressions; the remaining two expressions are meant to serve as non-examples that address common misconceptions; for instance, Condensed Expression E, log(8), is meant to trap students who believe log(6) + log(2) = log(8), rather than using their calculato
