For this task, students view four letters and imagine that each square in the picture measures one centimeter on each side. Students use this information to find the area of each letter.

Use this artifact as a resource for the standards 3.MD.5 & 3.MD.7. (Uses: exit ticket, quiz grade, center, re-teaching, teacher modeling, gallery walk, questions for math games)

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.

Learners will be given a series of challenges (challenge cards) and graph paper. They will need to solve the challenge and code their Ozobot to travel the length of the perimeter. They may opt to include color codes to impact the Ozobot’s travel.

Discover how square units can be used to cover the interior of a rectangle and measure its area of a rectangle in this interactive tutorial.

Students are given a scenario and must select three rectangles to show how they could use Jack's strategy of breaking apart a rectangle to find the area of each figure.

Recognize that area represents the product of two numbers.
Develop and justify a strategy that uses the area model to simplify a multiplication problem.
Represent a multiplication problem as the proportional area of a rectangle.
Looks for patterns in the total area calculation.

In this math game, students will explore the concept of covering a region with unit squares and score points for each correct response. Once they complete the round they can advance to the next level where they will multiply the length measurements to find the area of a rectangular region.

This resource provides a multiday station-rotation blended learning lesson plan for teaching Area and Perimeter.  

This short video and interactive assessment activity is designed to teach third graders an overview of area of squares and rectangles - word problems.

In this interactive demonstration, students select one of 6 array displays to illustrate 12 buttons. This virtual manipulative can help students to illustrate, represent, and explain multiplication and division problems.

This interactive virtual manipulative allows students to practice illustrating, representing, and explaining multiplication and division problems, as well as finding the area of a rectangle but moving rows and columns to visualize arrays.

This lesson focuses on real world examples of rectangular arrays as well as a real world problem.  The students creatively search for various examples of real world examples of rectangular arrays and then present their findings to the class using a technology tool.  The students are then posed with a real world task of determining the best arrangement of movie theater seats given the total seats of 50, 100, and 200, respectively.  This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

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.

Day 1:
In this lesson, students will…
Use Bee-bots to trace the perimeter of a rectangle. They will then prove their findings with equations that match the path that they coded.

Day 2:
In this lesson, students will…
Use Bee-bots to “drive” the area of a rectangle. They will then prove their findings with equations that match the path that they coded.

Students will use the design process to create a new pair of shoes.  Students will use multiplication to find the area and/or perimeter of their design.

In these 2 lessons students break apart rectangular regions to determine the areas of smaller regions and the larger region. 

Find the area of a shape by counting unit squares
Describe the relationship between area and perimeter
Build shapes with a given area and/or perimeter
Find the area of an irregular shape by decomposing into smaller, regular shapes (e.g., rectangles, triangles, squares)
Determine the scale factor of similar shapes
Generalize how area and perimeter change when scaling shapes
