About the store
I started my teaching experience at a high school in a rural California setting working with the children of migrant farm workers. I expanded my experience at a high school in Roseville California where the population reflected the center for the S&P railroad and a large Hewitt Packard complex. I now teach at Folsom Lake College in Folsom California. My students are a blend of families who live in the rural settings of the gold country and the children of those employed by Intel which has a research headquarters here. The unique blend of these students has helped focus my desire to develop math materials that help bridge the gap for lower income students so they can compete in the workplace of the high tech world in which they now live.

Sum Permutation
An introduction to basis permutations. Race cars with colors and numbers are used to introduce the concepts. 2 work pages start with a basic permutation. 2 more pages are bit more complex. The last work page is harder but the students are guided through it. A great magic effect ties it all together at the end.

5 Right Trianges to a Square
You are given 5 right triangles. You cut one of the triangles in half to get a total of 6 pieces. Arrange these 6 pieces into a square. This puzzle was first introduced by Sam Loyd in 1905. It is still popular today. The “square within a square” solution is the basis for several magic tricks. The Magic Square paradox on this site is one of them. The file has complete masters for printing the puzzle parts. It also has teacher support to help you develop a puzzle wall for you classroom.

Baffiling Boomerangs
Two arcs are shown to be different lengths. When the arcs are pushed through a tube the shorter arc become longer and the longer one becomes shorter. A great illusion. A history of the objects is provided. Class masters in color and black and white are provided.

The Magic Square Paradox
A Magic Trick and a Puzzle
A two sided puzzle with two magic squares. One side of the puzzle has 5 parts that can be formed into a square. The face of the puzzle has 9 numbers on it in the 3 rows and 3 columns. The sum of the numbers in each row, column and both diagonals total 45. It’s a Magic Square.
Take away one piece of the puzzle and turn over the other 4 puzzle pieces. These 4 puzzle pieces can also be formed into a square. The sum of the numbers in each row, column and both dia

Teaching style
I started to use math magic as the center of my materials. I am trying to develop material that can motivate reluctant students to practice their math skills. I also want to try and use material that makes them want to ask “why” this works and I have found math magic really allows this. As the student tries to find out the why behind the effect they must extend their understanding of the math concepts involved. This can really help develop critical questioning and critical thinking skills. Many of the activities I use have a “second level” of understanding that involves more involved math concepts and introduces both levels of students to major concepts in mathematics
