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.

The purpose of this lesson is to learn how to estimate square roots using different models.

Included is a YouTube video to support Grade 8 Blended Learning Math - Unit 1.4: Square Roots and Pythagorean Theorem - Estimating Square Roots.

Explore Learning offers 3 programs to support students learning at home:

Gizmos (Grades 3-12) Get hands-on with math and science.
Gizmos are online simulations that excite curiosity and invite interaction. We’ve got over 400 Gizmos in our library covering topics and concepts in math and science for grades 3-12. Gizmos help students dig deeper into subjects and really understand challenging concepts.

Reflex (Grades 2-6) When they use Reflex, kids love math.
Adaptive and individualized, Reflex is the most effective system for mastering basic math facts in addition, subtraction, multiplication and division.
Full of games that students love, Reflex takes students at every level and helps them quickly gain math fact fluency and confidence. And educators and parents love the powerful reporting that allows them to monitor progress and celebrate success.

Science4Us (Grades K-2) It’s never too early to learn science!
Science4Us covers Inquiry, Physical Science, Life Science and Earth & Space Science with lessons specifically designed for K-2 students. The sessions have 1000’s of online and offline activities that can be completed in as little as ten minutes, and teach students using videos, interaction, poems, songs, and digital notebooks.

"Kids can use this as a resource for a variety of subjects. With biographies, an atlas, and other reference materials, Factmonster is an informative place for kids to find fun facts and play educational games." (Common Sense Media)

Resources are organized across the top toolbar by subject, homework, games and tools.

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.

Math-Drills.com includes over 50 thousand free math worksheets that may be used to help students learn math.

Give a 5 question mixed review quiz to students every Friday.The questions can focus on current learning, but should also include questions from the entire year (especially concepts needed for next week's lessons, or foundational items that need to be mastered). This strategy will help develop mastery, provide opportunities for mixed practice to ensure comprehension beyond specific learning content.  

MathScore helps students acquire a deep understanding of math by providing adaptive math practice that functions like self-guided lessons. MathScore is fun and improves math confidence and grittiness. For any important math concept, we help students achieve mastery in 3 phases:
1. Develop relatable, definition-level understanding:
2. Develop computational excellence: Using adaptive techniques, we efficiently develop strong computational skills.
3. Develop analytical understanding.
