How to Build Polyhedra
How to Build Polyhedra is a site with construction instructions for building about 50 polyhedra. Construction information is simple enough for anyone from middle school students through adults to understand.

How to Build Polyhedra

We've created Yummy Math to provide teachers with an easy way to bring real-life into their math classrooms. It is our belief that when math is explored in contexts that are familiar and of interest to students, students will be more engaged to do math, reason, think critically, question and communicate.

Teaching Math 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.

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.

Hospital Clock Site
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.

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.

Polyhedra site

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.


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.
