This site offers math and logic problems for ages 5 and up to adult.

A collection of lessons, calculators, and worksheets created to assist students and teachers of algebra.

The inspiration for this site came from John Allen Paulos' book Innumeracy. From it Fawn Nguyen took the mathematical fun facts, etc. and created middle school mathematics critical thinking problems that relate to ratios and proportional reasoning and require students to compare stuff and really get them thinking.

Here's an example:
Tortoises have the longest lifespan among vertebrates, about 200 years.

A fruit fly's lifespan is about 45 days.
​
If we scaled both lifespans down so that a tortoise's 200 years is now 1 day, then what is the fruit fly's lifespan, in seconds?

A series of pamphlets has been developed with the goal of supporting parents and caregivers as they promote positive math thinking in the home. The printable pamphlets, developed in collaboration with sector partners, also provide an overview of what students will be taught in school in each of grades 1-9, based on Saskatchewan curricula.
