This parent guide supports parents in helping their child at home with the 3rd grade Math content.

This resource accompanies our Rethink 3rd Grade Math Course. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

This lesson is for Grade 3 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation.  Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.

In this online activity, students will have the opportunity to push their understanding of loops to a whole new level. Playing with the Bee and Plants vs Zombies, students will learn how to program a loop to be inside of another loop. They will also be encouraged to figure out how little changes in either loop will affect their program when they click `Run`.

This short video and interactive assessment activity is designed to teach fourth graders about dividing by 8.

Sample Learning Goals:
Explain how multiplication tables help understand multiplication, factoring, and division.
Use an array model to understand multiplication, factoring, and division.
Increase accuracy in multiplying, factoring and dividing.
Develop multiple strategies for arithmetic problems.

This task helps to define the relationship between multiplication and division. Students will use the fish tank scenario and the more familiar multiplication expression to relate these two operations to one another.

In this lesson, students will use multiplication strategies to find solutions to division expressions. This is remixable.

This task aligns to 3.NBT.3. This is remixable if you are able to add samples of student work.

In this lesson, students interpret the unknown in division using the array model.

In this lesson, students model division as the unknown factor in multiplication using arrays and tape diagrams.

In this lesson, students interpret the quotient as the number of groups or the number of objects in each group using units of 2.

In this lesson, students interpret the quotient as the number of groups or the number of objects in each group using units of 3.

In this lesson, students learn how to solve two-step word problems involving multiplication and division, and assess the reasonableness of answers.

In this lesson, students learn how to solve two-step word problems involving all four operations, and assess the reasonableness of answers.
