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.

This site offers 4 free math activities to assist students with increasing their fluency in operations with rational number and algebraic equations. The activities include:
Activity 7.7: "Would You Rather..." Routine
There are two versions of this routine with systems of linear equations—choosing different strategies (e.g., Use Tables or Use Graphs) and making choices within a strategy (e.g., For which variable will I substitute? Or Which variables will I eliminate?).
Activity 6.10: The Transformer Game
This game is a fun way to give students opportunities to choose and use different basic transformations to start solving equations.
Activity 5.7: Worked Examples For Ratios and Proportions
Use this activity for worked examples for ratios and proportions. Correctly worked examples and partially solved worked examples benefit students so that they can understand strategy.
ACTIVITY 4.11: Quotient Connect Game
This game is an engaging way to practice division using Partial Quotients. It is played similarly to the classic board game Boggle as students find quotients through connected digits.
