This is an interactive 3rd grade lesson plan to reinforce 3.MD.5, 3.MD.6, and 3.MD.7 the concept of area. This lesson will most likely span over the course of a couple of days. Thumbnail "farm scene" by Christian Collins, Creative Commons license CC BY-SA 2.0.
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.
This activity is intended to assess your 3rd grade students' ability to find area and perimeter of rectangles and squares. Students will be creating a robot using Google Drawing. They will then find the area and perimeter of each piece of the robot. Once they have found the area and perimeter for each shape in their robot, students will calculate the total area and perimeter of the robot. Photo by Eric Krull on Unsplash
This series of problems requires students to apply their knowledge of area and perimeter to find the optimal area given a specified amount of fencing. The problems progress in difficulty as new elements are added to the situation, therefore changing the outcome. This page includes tips for getting started, solution, teachers resource page, and a printable problem page.
This activity gives students the chance to explore area and perimeter in a problem solving setting. Nine differently-sized squares need to be tiled into a rectangular frame of unknown proportions. Three prompts of solving strategies are provided. Ideas for implementation, extension and support are included along with a printable sheet of the problem.
This problem encourages children to identify and describe a pattern and to extend the pattern into a general rule. Using an applet, learners try to discover the number of garlic cloves being planted if the arrangement into various rows always finds that there is one left over. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for support and extension.
In this assessment lesson, students review key information about perimeter before participating in a variety of assessment activities. Using this assessment, teachers are able to assess student understanding of measuring the perimeter of polygons.
Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.
