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.

Matching Activity: Quadratic Equations--identifying a, b & c
These cards are for cutting up. Students then work in pairs or small groups to identify the matches. This was designed to help students practice identifying the values for a, b and c in quadratic equations written in various forms. Directions include five possible uses for the cards and an answer key. The quadratic equations are not all written in standard form, so this will require the students to do some algebraic manipulations.

Finding Patterns Painted Cubes
This problem starts with a 1 by 1 by 1 painted cube. Then builds to a 2 by 2 by 2 painted cube, then 3 by 3 by 3 painted cube, etc. Students are asked to count the number of 1 by 1 by 1 cubes that have paint on all six faces, three faces, two faces, one face and no faces. There is a table that has some of the information filled in to help the student find the needed information and then they are asked to try to generalize the patterns found.
This works really well if you have cubes to give the

Fraction Pyramid denominators 2-12 (one pyramid on page)
This version includes: halves, thirds, fourths, fifths, sixths, sevenths, eighths, ninths, tenths, elevenths, and twelfths. I ran this page off on both sides of a paper and put it inside a sheet protector. I gave one to each student along with a dry erase pen. If each bar represents a "one unit" I can ask students to shade a bar to represent a specific fraction. If I ask them to shade in ½, there will be multiple answers, which provides an opportunity to strengthen the discussion of equivalent f

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

These are paper versions of bar shaped tools to model fractions. Each denomination (n) includes the 0/n, 1/n, .... n/n. This version includes all denominators 2-12. [There is another set of each of these resources that uses only halves, thirds, fourths, fifths, sixths, tenths, and twelfths.] Ideally each student would get their own set with which to work. There is a completed version at the end of document. It is somewhat distorted due to space constraint, but the answers are visible. Since

Quotients with Exponents
This scaffolded activity allows students to see the patterns that arise when working with quotients of numbers and variables that have exponents. The process, and the mantra ""When in doubt, Write it out!," allow students to recreate the learning if they forget it later. This is preferred over remembering rules for exponents which often get mixed up.

Experience

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.
Additional biographical information
Did I mention that I love math? I have presented workshops at local, state and national conferences for math teachers for almost thirty years.
