This resource is an anchor chart for the standard 3.MD.8. It includes the definition of perimeter, how to find perimeter when all side lengths are given, and how to find the missing side length when the perimeter of rectangles and other polygons are given. This resource could be added to a digital learning wall for students to refer back to throughout the school year as needed. (Padlet, Google Slides, Etc.)
This resource can be used through Google Slides or Peardeck. The Mini-Lesson will cover the following “I Can” Statement.I can find the missing side length of a rectangle when given the perimeter.
This resource can be used through Google Slides or Peardeck. The Mini-Lesson will cover the following “I Can” Statement.I can use the given perimeter to find all side lengths of a regular polygon.
This resource can be used through Google Slides or Peardeck. The Mini-Lesson will cover the following “I Can” Statement.I can find all possible dimensions of a rectangle when given the perimeter.
This resource can be used through Google Slides or Peardeck. The Mini-Lesson will cover the following “I Can” Statement.I can use the given perimeter to find one missing side length of a polygon.
This resource is a worksheet for the standard 3.MD.8. It can be used as an exit ticket or as an independent practice. This could be used with a tech tool where students can draw directly on the document (Nearpod, Peardeck, Seesaw, Etc.)
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.
This short video and interactive assessment activity is designed to teach third graders an overview of area of squares and rectangles - word problems.
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.
This unit contains a curriculum-embedded Common Core aligned task and instructional supports. The task is embedded in a 3-4 week unit on solving real-world problems to reinforce the strategies of tiling, multiplication, addition and area models to calculate the perimeter and area of polygons. In addition, students will need to demonstrate and explain their reasoning of strategies used to solve the task.
This short video and interactive assessment activity is designed to teach second graders about using real maps (english lengths and distances).
This lesson is designed to challenge students to learn about how geometry and measurement are used in the real world by architects. The students will explore various concepts such as area and perimeter as well as developing benchmarks for measurement. 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.
Students develop and solidify their understanding of the concept of "perimeter" as they engage in a portion of the civil engineering task of land surveying. Specifically, they measure and calculate the perimeter of a fenced in area of "farmland," and see that this length is equivalent to the minimum required length of a fence to enclose it. Doing this for variously shaped areas confirms that the perimeter is the minimal length of fence required to enclose those shapes. Then students use the technology of a LEGO MINDSTORMS(TM) NXT robot to automate this task. After measuring the perimeter (and thus required fence length) of the "farmland," students see the NXT robot travel around this length, just as a surveyor might travel around an area during the course of surveying land or measuring for fence materials. While practicing their problem solving and measurement skills, students learn and reinforce their scientific and geometric vocabulary.
