English Description:
This 40-day final module of the year offers students intensive practice with word problems, as well as hands-on investigation experiences with geometry and perimeter. The module begins with solving one- and two-step word problems based on a variety of topics studied throughout the year, using all four operations. Next students explore geometry. Students tessellate to bridge geometry experience with the study of perimeter. Line plots, familiar from Module 6, help students draw conclusions about perimeter and area measurements. Students solve word problems involving area and perimeter using all four operations. The module concludes with a set of engaging lessons that briefly review the fundamental Grade 3 concepts of fractions, multiplication, and division.

Students work in teams to design a tabletop supply organizer inspired by the natural home of an insect species. Their prototype stores the group’s classroom supplies (scissors, crayon boxes, pencils, and glue sticks). In addition to following measurement constraints that apply to their prototype, students must design their supply organizer with the idea that supplies must be easily retrievable and the organizer must be sturdy enough to withstand everyday classroom wear and tear. Students test their prototype in the classroom for a period of 5 days and evaluate its effectiveness.
In this lesson on area and perimeter, students will learn how to find the area and perimeter of rectangles by applying formulas.
In this lesson on circles, students will learn how to find the area and circumference of circles, semicircles, and compound shapes using formulas.
In this lesson on finding the perimeter of rectangles, students learn key vocabulary, explore grid paper, and apply their learning to a real-world situation.
This video geometry lesson [6:14] explains the concept of perimeter and has varied exercises for students to practice.
Use this applet to find the perimeter of a variety of shapes with the same or different areas.
This short video and interactive assessment activity is designed to teach third graders about perimeter in grid.
This short video and interactive assessment activity is designed to teach third graders about perimeter of squares and rectangles.
Students connect algebra to geometric concepts with polygons as they explore the distance formula, slope criteria for parallel and perpendicular lines, and learn to calculate and justify the area and perimeter of polygons.
Word problems are provided for practice with area & perimeter of rectangles. Immediate feedback is given and hints or a video are available if needed.

Students solidify their understanding of the terms "circumference" and "rotation" through the use of LEGO MINDSTORMS(TM) NXT robotics components. They measure the circumference of robot wheels to determine how far the robot can travel during one rotation of an NXT motor. They sharpen their metric system measurement skills by precisely recording the length of a wheel's circumference in centimeters, as well as fractions of centimeters. Through this activity, students practice brainstorming ways to solve a problem when presented with a given scenario, improve their ability to measure and record lengths to different degrees of precision, and become familiar with common geometric terms (such as perimeter and rotation).
Students learn and practice how to find the perimeter of a polygonal shape. Using a ruler, they measure model rooms made of construction paper walls. They learn about other tools, such as a robot, that can help them take measurements. Using a robot built from a LEGO® MINDSTORMS® NXT kit that has been programmed to move along a wall and output the length of that wall, students record measurements and compare the perimeter value found with the robot to the perimeter found using a ruler. In both cases, students sketch maps to the scale of the model room and label the measured lengths. A concluding discussion explores the ways in which using a robot may be advantageous or disadvantageous, and real-world applications.
Students learn how different characteristics of shapes—side lengths, perimeter and area—change when the shapes are scaled, either enlarged or reduced. Student pairs conduct a “scaling investigation” to measure and calculate shape dimensions (rectangle, quarter circle, triangle; lengths, perimeters, areas) from a bedroom floorplan provided at three scales. They analyze their data to notice the mathematical relationships that hold true during the scaling process. They see how this can be useful in real-world situations like when engineers design wearable or implantable biosensors. This prepares students for the associated activity in which they use this knowledge to help them reduce or enlarge their drawings as part of the process of designing their own wearables products. Pre/post-activity quizzes, a worksheet and wrap-up concepts handout are provided.
Students are introduced to the more abstract concepts of points, lines, line segments, rays, and angles, as they learn to measure angles and then analyze shapes by their angles and lines of symmetry.
Students explore concepts of perimeter and geometry, specifically measuring perimeter. They start by exploring the specific attribute of perimeter, and then come to differentiate between perimeter and area as different measurements.
