Arc Midpoint Algorithm
 
Gregory and Oleksandr have built on the arc midpoint resource and the proof of the arc midpoint formula by constructing an algorithm for finding the coordinates of the midpoint. It is hoped that teachers of high school Mathematics and Computer Science will use these resources to enrich the teaching and learning in both subject areas.
Atlatl Lessons Grades 4-12
 
The atlatl and dart, the predecessor to the bow and arrow, was very important in the lives of Aboriginals in Saskatchewan and all over the world up until about 2000 years ago. Experiment based lessons allow students to learn about the science behind the weapon system that put humans on top of the food chain. Subject integrated lessons for grades 4-12 in the areas of math, science and social studies based on Saskatchewan curriculum objectives.
Car Park Data (HTML or PDF)
 
This teacher has used information from cars in the school parking lot as an easily accessible resource from which to collect and process data.
Complex Numbers
 
This note is a response to a teacher's request for an explaination of i squared and the square root of i that would be appropriate for secondary level students.
Conditional Probabilities and False Positives
 
A conditional probability example where your intuition may lead to a poor estimate of the correct probability. The situation described results from false positives in a medical diagnostic procedure.
Consumer Math 10
 
This Stewart Resources Centre unit is designed to assist students in the calculation and estimation of income and expenses, the development a budget to guide current and future planning and to communicate a summary of financial projections in appropriate reports, tables and graphs.
Consumer Wise (HTML or PDF)

Income, Budgeting and Credit, Saving and Loans are a few of the topics discussed in the activities. Worksheets for the activities are included in this unit as well as objectives, evaluation and resources ideas.
Data Management
 
This is the lead article in the fifth edition of Ideas and Resources for Teachers of Mathematics, a newsletter published by the Saskatchewan Mathematics Teachers' Society. The topic of the fifth edition of the newsletter is data management and in this article Vi introduces the topic and presents the view that statistical inquiry by students be developed through authentic developmentally appropriate and curriculum-relevant activities.
Data Management and Analysis: Secondary Level Ideas
 
This one of the articles in the fifth edition of Ideas and Resources for Teachers of Mathematics, a newsletter published by the Saskatchewan Mathematics Teachers' Society. The topic of the fifth edition of the newsletter is data management and in this article Jeff outlines how he uses resources and data from the internet to motivate and develop the concept of standard deviation.
Data Management and Analysis: Secondary Level Ideas
 
This is one of the articles in the fifth edition of Ideas and Resources for Teachers of Mathematics, a newsletter published by the Saskatchewan Mathematics Teachers' Society. The topic of the fifth edition of the newsletter is data management and in this article Walter shows how he uses data collected from the internet to construct box and whisker plots.
Deriving the Slopes of the Angle Bisectors
 
In this note Gregory uses a trig identity to develop an expression for the slopes of the angle bisectors of two lines in terms of the slopes of the lines that form the angle.
Diamond Slopes and Speedy Whales via… One Identity
 
A trigonometric identity is used to develop a formula for the slope of a rhombus diagonal. This expression is then used to find the velocity of a whale.
Direct and Partial Variations (HTML or PDF)
 
A unit on direct and partial variation that can be taught after the introduction of linear functions.
Divisibility of 2n choose n by a prime. (HTML or PDF)
 
Question in Quandaries and Queries about the divisibility of 2n choose n by the product of three primes. This note addresses the simpler problem of the divisibility of n! and 2n choose n by individual primes.
Donuts and Do Loops
 
In this note Penny shows a connection between the number of ways you can buy a dozen donuts from an unlimited supply of 5 types of donuts, and the number of operations a computer performs as it goes through a do loop.
