Grade 3 Math Resources

Dear Parents, Guardians, and General Math Helpers Outside of the Classroom,

Welcome to the Eureka math resources for CCSS students' helpers. Not all of these curated resources were created by us, but we have collected them for you so that you can get an idea of what your student's lessons focus on in class and help, if needed.

If you have a student in school today, you probably learned the foundations of math in a very different way. You and I learned the art of "answer getting," and we were good at it. Well, some of us were...some of us needed the math knowledge about numbers that really wasn't taught in class. We were instructed to follow formulas (algorithms) and not ask, "Why?" Some of us picked up a working number sense over time as we got older and learned, by experience, in real world settings.

Your children are now learning that number sense you learned as an adult in their classes today. What would the learning process look like if you taught kids how to think about math and not merely plug numbers into a formula? What would it look like to provide them with the skills to figure math out? Well, the learning process looks very different for our children than merely memorizing and getting answers. Of course that’s part of it, but not the foundation-building that is done in the beginning to understand the way math works.

We created this site to help you navigate this new mathematical arena. This site is a work in progress. We will add quality resources as we create or find them.

Use the concepts you see in these lessons to create fun activities around the house, in the store, at the park, or in the car. Number sense can be reinforced anywhere!

Please do not hesitate to contact your child's teacher if your child is struggling.

Thank you for partnering with us to provide the best education for your child.

Fluency Practice

At the beginning of third grade, students shoud be able to add and subtract to 20 and multiply from 0 to 72 (up to the 6's). These videos provide support for students who need to practice these skills.

By the end of third grade, students should be able to multiply to 144 (up to the 12's)
