Free Online Resources for Math Teachers

Updated List of Math Resources

Try these free, online resources for math teachers today. I scoured the web for fresh, low prep math content. Yes, there are some ads on a few, but I tossed out pages that had super annoying ads. Sites loaded with content are listed alphabetically if you scroll down a bit.  The links below are just a bite-sized ‘amuse-bouche’ to give you some ideas about what is available for your age group.

Kindergarten to Grade Three

Symmetry – Pressbooks

The Circle Song – TEDEd This song is addictive. Make sure there  is enough space to dance along.

Hungry alligator video The Kid Should See This

Area and Perimeter (on Mars, of course) – TEDEd

Speedy Animals – Slow Reveal Graphs

Addition with regrouping – Math Antics

Grade Four to Middle School

Geometric Patterns from Digit Sums ~ UnCommon-Core.com, a thoughtful review of multiplication and exploration of mathematic patterns (see image).

Polygons – Pressbooks

World Population as 1000 people – Visual Capitalist

Length of Years on Different Planets – Slow Reveal Graphs, a great starting point for conversations about leap year.

Measuring Distance to Stars – Scientific American Youtube  

Equivalent Expressions with Distributive property – Math Shorts Youtube

Multiplication Doubling and Halving – The Kid Should See This

Why are Manhole Covers Round?  TEDEd

Finding Unknown Angles – The Kid Should See This

Proportional Relationships Area – Math Minute

Equations of Lines in Point Slope form – Magic of Math

Alphabetical List:

ACS Educational Resources – Science IS Math. While the American Chemistry Society isn’t focused directly on online math resources for teachers, many of their activities can be used to connect math with science in a meaningful way.

Bedtime Math – Bite size puzzles for elementary students and parents (or teachers) to use when you are looking for something different.

Brilliant for Educators – Free for qualified K-12 teachers and reduced prices for homeschooling or tutoring! Fantastic resource for you and your students. This is the site I use when I want to brush up on my math skills!!

Classroom Timers ~ there are many options for you and your students to explore. Timers help students focus on the task at hand, as they don’t have to spend time wondering when it will be done. Timers lend a sense of urgency that some value while other students tense up. 

• Online-stopwatch.com
• Toy Theater
• We Are Teachers

Discovery Education – Puzzle Maker  I have been messing around with this puzzle making page ever since I found it. Add the details you want and the site does the rest. This offers an easy way to personalize handouts for your students ~ add their names, vocabulary or spelling words, or the specific math facts your class needs to practice. 

GeoGebra – You can use this site in at least two ways. If you have young students, why not create something for them to use in class? Older students, of course, will want to dive in and try it for themselves.

The Magic of Math – youtube channel, Focuses on middle school math in straightforward language and well planned presentations.

Math Antics – youtube channel, As with any resource make sure your students know the vocabulary used before sharing. 

Mathigon/ FACTRIS – Just WOW. The entire Mathigon site is worth exploring, however FACTRIS is my personal favorite. For students who need to review multiplication facts, prime numbers, or factoring, this game will quickly become their favorite (and yours).

Math Learning Center – Learning opportunities for Pre-K to Fifth with printable versions.

Minute Math – youtube channel, Short, focused and well organized explanations of mathematical concepts.

Mathnook – has adds, however it also has a lot of fun math games and worksheets.

MoMath The National Museum of Mathematics~ A real Museum of MATH!! Even if you are not located in New York, you and your students can benefit from keeping tabs on what’s new at MoMath.

Math Playground – fun interactive games

NRICH – packed with everything you need to expand and explore topics in depth, from The University of Cambridge. Interactive resources for elementary students (scroll down forever!) – Suggestions for books that link to specific concepts (organized by UK standards so you may have to poke around a bit to find what you are looking for) – activities – maths by topic (yes there is an S). I linked to examples of elementary resources, however there are similar resources for students up to grade 12.

PBS KIDS MATH GAMES – PBS comes through again with interactive math games for young students.

Prodigy Math – Teachers can sign up for free to access the games and information.

SCIAM ~ Scientific American youtube channel,  there are videos for children about math, however most of the content on this site is about scientific questions. This fantastic resource will help you connect math with science and with some everyday questions: What if Pi Were a Song?   Sunflower (Fibonacci) math!

SCIGames – Fantastic interactive science games, multilevel puzzles, and info. Engaging way to connect math with science. If you don’t hear from me for a while – I’ll be on this site, flying to Mars.

Slow Reveal Graphs  ~ Unique, low prep lessons for students of all ages. Here’s an entire post on selected highlights from the site.

Super Star Worksheets – free PDFs math and more; talk about low prep!

TEDEd – customizable lessons with short videos, TEDEd has lessons on many topics for every age. If you don’t see what you want,  you can post your own. 

The Kid Should See This/math –  Tons of videos of interest to everyone! It is essential to preview each resource; the site has been active for a while and some videos are cut short or have been removed. Check first. If this link doesn’t work, search for the site on your favorite search engine.

Planarity – math game like no other. There is no algorithm that will solve puzzles like this; yet this kind of mathematical problem shows up in real life all the time. Your students might not be ready for planar graphs, but they will love Planarity. When you arrive on the site the number of dots is set at 8 – however I would let students try 4 and then 5 for a long time in order to get used to the game. Yes, there are some ads, but try to ignore them.

Puzzleplayground – free site with interactive games for many ages.

Press Books Mathematics for Elementary Teachers ~ I’m interested in knowing what you all think of this site. (Yes, I’ve lived in Texas, where ‘you’ is singular, ‘you all’ is plural, and ‘all you all’ is . . . well, more plural.)

UnCommon-Core.com ~ In the US the Common Core State Standards show teachers what to teach; UnCommon Core helps teachers decide how.  UnCommon Core is an independent organization, run by yours truly, dedicated to creating earthshaking resources to help teachers make math sticky.

Visual Capitalist – yes really! After I spent way too much time drooling over the infographics on this site, I wondered if I should include it in a post focused on math resources for educators. Even though this site was not created to teach math, the way they display data and some of the topics of the data displayed could be useful in math class. It could help you link math with other subjects. It will require planning and preparation to use this in your class. 

WILD MATHS – Wild Maths is for upper elementary and middle school students who are ready for something interesting to sink their teeth into. These interactive games give context to abstract mathematical concepts.

Check content carefully, of course

I’m excited about these free resources. I believe they will help math teachers by providing you with valuable material that is ready to use in class. However, as you know, each class is different; what works well in one educational setting could flop in another. With this in mind, please preview the entire video, lesson, slide deck, or information to make sure you and your students will benefit.

Finally, if you work with students in food insecure homes, students with diabetes, allergies, or other challenges, think carefully before using resources about food. This would also apply to students from religious families during Lent, Yom Kippur, Ramadan or other times of fasting.

I hope you and your students will benefit from using these and other math resources from UnCommon Core!

All the best,

Isabelle
