Yummy Math       This site presents timely and relevant math lessons for mathematics teachers. It is our hope that this will become a repository of meaningful mathematics for your classes to enjoy.

Recognizing Special Numbers       This site gives students a practice drill for becoming familiar with the perfect squares (from 1² to 25²), the perfect cubes (from 1³ to 10³), and many Pythagorean Triples.

Teaching Mathematics with Art      This site shows 4 projects that can be used in middle or high school to help students become engaged in mathematics and be able to visualize the concepts involved. Lovely examples of students' work and project instructions for the teacher are included.

How to Build Polyhedra       This site gives simple instructions and picture guides for creating about 40 polyhedra.

Data_Analysis_Checkup      This site helps students remember what they have learned about line plots, box and whisker graphs, stem and leaf plots and Mean Absolute Deviation. Students can learn the material as new, review terms, practice skills, or skip the sections where they have confidence. Four nightly assignments are included. We use this site for MCAS review.

Graph Aerobics         This site encourages students to use their bodies to pose as different 1st and 2nd degree graphs while moving with music. This activity can be used after students have completed a unit on graphing and have had opportunities to stand and try to pose their arms as Y=X, Y=X2, etcetera. Very fun and slightly silly.

This site is a visual presentation of Theo May's clock geometry. Mr. May had the opportunity to do mental math with the only entertainment in his hospital room, a clock. He creates an analysis of the exact times when clock hands coincide, are at given angles to each other, or are symmetric around different clock axes. This is an excellent enrichment study for geometry or algebra students dealing with pursuit problems.

Polyhedra                 This site shows the final creations of several 8th grade students. The polyhedra shown are the results of a two week at-home assignment. Their creations are lovely.

Biography for Leslie Lewis   This is an overview of my web designs and many samples of my students' artistic work. There are instructions for teachers to use for each of the projects.
