Hands-On Geometry (HTML or PDF)
 
This Stewart Resource unit describes the use of manipulatives in to study lines, line segments, angles and polygons.
Math on the Farm
 
This article discusses some of the many ways in which math is used in agriculture. It considers specific agriculture processes, as well as a variety of math concepts.
Pattern
 
This is the lead article in the seventh edition of Ideas and Resources for Teachers of Mathematics, a newsletter published by the Saskatchewan Mathematics Teachers' Society. The topic of the sixth edition of the newsletter is petterning and algebra. In this article Vi and Rick introduce the concept of pattern through some ideas from literature and through a recent 'pattern' experience.
Pi Day Pie with Two..Foci
 
Gregory gives a challenge problem with an elliptic pie.
Puzzle Brings... Olympic Rings
 
Gregory poses a challenge problem involving the Olympic Rings.
Pythagorean theorem research project
 
A student wrote to Quandaries and Queries looking for tips for a research project he had to write on the Pythagorean theorem. The reply from Jack and Walter has some good ideas that some teachers may find useful.
Size small school
 
In this grades 7 to 9 activity students make measurements of their school and then construct a scale drawing.
Surface Area to Volume Ratio
 
Help student discovery the relationship between surface area and volume through various activities. Once concept is attained, follow up with activities on where the surface area to volume ratio is found in the real world.
Tantalizing Tessellations!! (HTML or PDF)
 
This unit was written by three students as a project in a mathematics education class, EdMath 215, at the University of Regina.
The Arc Midpoint Find
 
Continuing his discussion of circular arc midpoint computation Oleksandr develops an expression for the midpoint of a circular arc in n dimensions.
The Map of the Land & Symbolic Extent
 
Another challenge problem from Gregory, this time concerning the map of Saskatchewan.
The Triangle Problem
 
This resource is a description of an unsolved problem in geometry dealing with reflected triangles. The problem led one of the authors, Nathalie, to devise an algorithm and resulting graphic in an attempt to study the problem. This graphic was used as the background image on the Mathematicians at Work poster which is part of the Mathematics with a Human Face project.
Towards a Better Understanding of Pi Using the Idea of Limits.
 
Ed describes here an activity that students can undertake to approximate pi. It is adapted from the process used by Archimedes in about 240 BC. Students who work through this activity will improve their understanding of pi.
What are real world applications of trigonometry?
 
Students often ask where they will ever use trigonometry or why they need to study it. This note contains a use of trigonomerty in two areas where its use might be unexpected. One situation involves an artisan who needs the dimensions for a metal sculpture he is constructing and the second a homeowner who is disputing her property assessment.
Why are satellite dishes parabolic? (HTML or PDF)
 
A development of the mathematics which shows that a parabolic shaped satellite dish will focus the signal from a satellite to the focus of the parabola.
