Strand: MEASUREMENT AND DATA (3.MD)

Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects. (Standards 1–2). Represent and interpret data (Standards 3.MD.3– 4). Understand concepts of area and relate area to multiplication and addition (Standards 3.MD.5–7). Recognize perimeter as an attribute of plane figures and distinguish between linear and area measures (Standard 3.MD.8).

Standard 3.MD.8

Solve real-world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

• Area Explorer
The applet in this activity generates a random geometric figure and allows the student to test their understanding of how to find the volume of an area.
• Fixed Areas
This lesson plan activity helps students understand the relation between area and perimeter.
• Grade 3 Mathematics Module 7: Geometry and Measurement Word Problems (EngageNY)
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.
• Junior Architects
This unit of 4 lessons leads students to design a clubhouse and thereby review two- and three-dimensional shapes, calculate perimeter and area, and create blueprints and three-dimensional models.
• Length, Perimeter, and Area
This lesson will help students understand how to find the area and perimeter of a random shape and a random triangle.
• Perimeter
This lesson plan and activities will help students understand the concept of perimeter.
• Perimeter (elementary)
This lesson will help students find the perimeter of rectangular shapes and irregular shapes with right angles.
• Shape Builder
This activity allows the student to explore area and perimeter by either allowing the computer to randomly draw a shape on a grid or build the shape on the grid.
• Shape Explorer
The applet contained in this lesson allows the student to test his or her skill at calculating the area and perimeter of a various figures.
