Best Math Websites for Teachers

Anyone who has ever stepped inside a math classroom knows that it can be a challenge to keep learners engaged, especially with sometimes vastly varying skill levels and interest in the subject. Luckily, there are a huge number of online math resources to help teachers who need lesson plan inspiration, professional development, fun games to get students excited about the topic, or just some extra worksheets and practice for struggling students.

Annenberg Learner

Why we like it: Teacher professional development is a constant learning process, but sometimes finding good resources is a challenge. This site provides both videos and written PD you can use to make your classroom even better.

Arithmetic Four

The Calculator Site

Why we like it: Often students get hung up on how to convert units, change from decimals to fractions or use order of operations and resort to relying on their calculators to give them the answer. This site allows them to do that, but includes explanations and step-by-step instructions that explain how the calculator is getting them the right answer.

Census at School - U.S.

Why we like it: Project-based learning is all the rage right now, and this site allows students to do a Census of their class and compare their class with random samples of students, both within the US and abroad, giving them some global insight along with their statistics practice.

Why we like it: Graphing calculators are expensive and gone are the days where every math teacher would have a class set. The abilities of graphing calculators are priceless when it comes to helping students understand complex problems without spending tons of time graphing out equations. Desmos provides all the functionality of a graphing calculator, but available on the web.

Figure This!

Why we like it: Getting parents involved makes a huge difference when it comes to student success in school. This site has fun math games and challenges that incorporate the whole family, getting everyone to work together to figure it out.

Free Rice

Why we like it: Students compete to see how many answers they get right, and for each one, the World Food Programme donates 10 grains of rice to those in need. It’s a great way to teach compassion and other social-emotional skills, while having students practice their math. Students have to have a free account to track their progress.


Why we like it: Interactive games organized by grade level make this a good resource for students to get extra practice without realizing they’re studying math.

Why we like it: YouTube can be a great place to find tutorial videos to share with your students, but you run the risk of inappropriate ads or comments ruining the experience.
