About the store
With over three decades in the classroom, I've taught in every type of school imaginable. During the last thirty years, I've scribbled on chalkboards, whiteboards, and smart boards in public, private, charter, international, IB, and even a school for juvenile offenders. I've rotated my way through algebra, geometry, trigonometry, and calculus. Prior to teaching internationally, I was only in high school classrooms. Now, I am additionally certified in both MYP and DP within the IB program.

Coffee Costs; Using Linear Systems In Business
In this activity students will learn how linear systems can be used in a business to predict at what point the business will break even after any projected costs. The learners will use all three methods of solving a linear system to find the points of intersection, or the point at which a business will have recouped their costs, in two different scenarios. They will first consider a plan where a producer simply grows and sells unprocessed coffee beans to a distributor. Then they will be presente

Trigonometry & Triangles; Showing How 2 "Same" Things Are Not Equal
This activity uses the basic trigonometric ratio to show that it is possible for shapes to have equal measures but still have different areas. Using cell phones as an example, the students will compare two different cell phones that have the same screen size, but different aspect ratios, and prove that the same screen size does not necessarily equate to the same amount of screen area. They will find the length of the sides using all three trigonometric functions, and then calculate the area. The

Teaching style
No matter where you teach, kids are still just kids. No matter the type of school, or where it's located, how I relate to the students never changes. When I was growing up I didn't respond well to the cookie-cutter approach, the idea that there's only one way to learn a concept. Each student in my classroom is expected to be an individual in the learning process. I don't expect them to learn like the kid next to them or like I do. I follow their solutions versus making them follow mine.
