About the store
I retired from a 30-year career as high school math teacher. I am actively involved in providing professional development for math teachers grades 4-12. My passion is helping students (of all ages) get through prior stumbling blocks to learning math in a meaningful way. It is very important to me that activities, presentations and all documents used for learning look professional. I have been a lead person in my district for creating benchmark exams used by thousands of students. I helped create a website for our teachers that contains classroom activities that are ready to use.

Right Triangle Trig Ratios for Visual and Kinesthetic learners
The notes that come with this graphic provide detailed steps for teaching the vocabulary of "hypotenuse," "opposite" and "adjacent" sides in right triangles. This vocabulary provides the basis for the rest of the notes about trig ratio definitions (sine, cosine, and tangent). The techniques are designed for visual and kinesthetic learners. This method easily shows why the sine of one acute angle is equal to the cosine of the complementary angle.
There is one page of notes and six pages of grap

Teaching style
Since I am a visual learner, I believe in using color to help accentuate connections in concepts. Besides including graphics with my activities, I try to present material in multiple modalities. I firmly believe that all students can learn math and excel in it. I have a "growth mindset," and work to help others understand how that can help them learn math. My favorite thing to say to any person who says, "I'm not good in math," is "You aren't good in math YET!"
My own education history
Masters of Arts and Bachelors of Science degrees in Mathematics from San José State University. Single Subject teaching credential in mathematics also from San José State University.
