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

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 website has various video challenges with accompanying PDF's for student use . Students are able to post their own videos of how they solved the challenge, and take a look at how others solved it as well.

The purpose of this lesson is to determine surface areas of composite objects made from cubes and other right rectangular prisms.

Included are the YouTube videos to support Grade 9 Blended Learning Math - Unit 1.3: Square Roots and Surface Areas - Surface Areas Made from Right Rectangular Prisms - Parts 1 and 2.

The purpose of this lesson is to determine the surface area of composite objects made from right rectangular prisms and right cylinders.

Included is a YouTube video to support Grade 9 Blended Learning Math - Unit 1.4: Square Roots and Surface Areas - Surface Areas of Objects Made from Other Composite Objects.

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.

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.

Math Antics has amazing videos to explain concepts for Math. The videos are very clear and explicit and students love them. All of the video lessons are FREE.

There are also follow up exercises, videos and worksheets that students can use to solidify learning - but you will be required to pay $20 a year to access these. hat being said, it's super useful even without a paid account!

The videos are organized by strand, and all are free.

They cover numeracy, arithmetic, algorithms, fractions, mixed numbers, percentages, ratios, geometry, statistics, measurement, exponents, integers & algebra, algebra 1-3

This amazing site from Alberta has interactive for all the strands.
These could be used by students or in small group instruction or as a whole class.

"The Problem of the Week is designed to provide students with an ongoing opportunity to solve mathematical problems. Each week, problems from various areas of mathematics will be posted here and e-mailed to teachers for use with their students from grades 3 and up."

This is great way to stretch your mathematical muscle and develop good problem solving skills (Understand, plan, solve, reflect).

Solutions are always provided!

Archives of past questions are also available.

"These Math Screeners were developed in response to the need expressed by teachers for a tool that would aid them in identifying specific skills and concepts where there were ‘gaps.’ Having this data will allow teachers to respond more effectively to students’ learning needs."

Math TV is an amazing collection of how-to videos in a variety of math subjects. Checking it out, I watched a video on how to multiply fractions and I (a teacher) learned a new method. Imagine what your students can learn.
