Tile Mural
Paste this resource into your lesson plans like you'd paste a tile onto a mural. Given a diagram of a tile mural with rectilinear figures, future artists determine the perimeters and areas of the figures. They must then develop their own...
Curated OER
Area
In this area activity, learners use square models or grid paper, estimate, then find the area of given shapes. Houghton Mifflin text is referenced.
Curated OER
Finding Perimeter and Area
Third graders understand the perimeter by units and now find perimeter by addition. In this perimeter lesson, 3rd graders relate their prior knowledge to adding the sides of the perimeter by answering a series of questions.
Curated OER
Area and Perimeter
Learners explore area and perimeter. In this math lesson plan, students differentiate between area and perimeter and compute the area and perimeter of an object.
Curated OER
Triangles
This unit enables scholars to apply the rule for area of a triangle (area equals half base times height). They practice multiplication and division strategies as they calculate areas.
Curated OER
Perimeter of Shapes
These squares and rectangles have length and width measurements with decimals; can young geometers determine the exact perimeter of each? Using a step-by-step example as guidance, they show work to find the perimeter of each of these...
Curated OER
Pacing a Gunther Chain
Students pace a Gunther Chain, a measurement used by foresters to determine distance and area. They discuss that pacing is individualized depending on age, gender, etc. They practice to find an average pace. Teams estimate, pace and...
Curated OER
"Polly"gon Pockets
Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...
Curated OER
It Takes Ten
Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

Fun on the Farm
Let imaginations run wild as participants design animal pens. A performance task challenges young mathematicians to determine the perimeter or a missing side length of different animal pens. They then design pens that meet given...
Curated OER
Measurement: Measuring Hand and Feet
Here is a good lesson which invites learners to practice measurement using standard and nonstandard measuring tools. In this measurement lesson, learners work with length, width, height, and area. They use standard and nonstandard...
Curated OER
Tiling Tessellations
Young scholars explore tessellations. In this shapes and geometry activity, students describe the attributes of many of the shapes displayed on an Elmo. Young scholars create examples of tessellations using pattern blocks.
Curated OER
Understanding Rational Numbers and Proportions
Students explore parts of a whole. In this fraction lesson, students determine what makes a fair share. Working with manipulatives, students solve mathematical problems containing fractions.
Alabama Learning Exchange
Dog Gone Again!
Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...
Curated OER
Shape Makes a Difference!
Learners learn the difference between perimeter and area by watching a video and a hands on activity.

Polygon Perimeters
What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Making Cubes
Third graders explore vocabulary associated with three dimensional figures. In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures. Students become familiar with describing two and three...
Pennsylvania Department of Education
Length and Perimeter
Third graders explore tessellations and the spatial concepts used in creating them. In this tessellations instructional activity, 3rd graders rotate, reflect and transform shapes to create tessellations. Students become familiar with...
Curated OER
Grade 3: What Can I Make with 30 Centimeters?
Third graders create polygons with perimeters of 30 centimeters, use the centimeter grid paper to determine the area of each shape, and organize the shapes to make generalizations from the patterns they see.
Curated OER
Building Patterns Constantly
Students are introduced to some number patterns using buildings constructed with squares. They construct tables of patterns and finding the recurrence rule for a simple pattern where the increase from term to term is a constant.
Curated OER
Geoboard Ideas
Students build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Students then switch with a partner to try an make a symmetrical shape.
Curated OER
Design an Apartment
Learners are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Multiplication Using Arrays
Explore the concept of multiplication by using arrays. Classmates use arrays to gain a better understanding of multiplication. They break arrays apart to model the distributive property of multiplication over addition. The relationship...
