Lesson Planet: Curated OER

#### What a Square

Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.

Lesson Planet: Curated OER

#### Visualizing and Naming Polygons

A really useful resource contains 116 slides covering basic geometric concepts related to 2-D or plane shapes. Shape properties, translations, reflections, congruence, symmetry, and grid work are all laid out in a comprehensive and...

Lesson Planet: Curated OER

#### Looking Through the Algebraic Lens

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

Lesson Planet: Curated OER

#### A World of Symmetry: Math-Geometry

Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Lesson Planet: Curated OER

#### Similar Shapes

In geometry, similar and congruent shapes are often confused. Shapes that are similar are the same shape, but a different size. This activity gives young learners some practice in identifying similar shapes. There are five polygons...

Lesson Planet: Curated OER

#### What Does Congruent Mean?

Two figures are congruent if they have the same size and shape. Line segments can also be congruent if they are of the same length. Vertical angles created by intersecting lines are always congruent. Polygons that have matching angles...

Lesson Planet: Curated OER

#### Congruent Polygons: Copying Stretchy Shapes

Third graders investigate congruent polygons through dance. In this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Lesson Planet: Curated OER

#### Spotting Polygons

See all sides of the story with a worksheet on geometric shapes! After studying the example at the top, which matches polygons with solid figures, second graders circle shapes that are named in the directions. Next, they match polygons...

Lesson Planet: Curated OER

#### Properties of Polygons, Same-Length Sides

Can your third graders spot the differences between these geometric shapes? After studying several sections of triangles, rectangles, and other polygons, learners circle the shape described in each set of instructions. For extra...

Lesson Planet: Curated OER

#### Properties of Polygons, Parallel Sides, and Right Angles

Have fun with shapes! Third graders read a set of instructions and circle the shape in the description. They work on recognizing parallel sides and right sides. Use this resource as homework after your geometry lesson.

Lesson Planet: Curated OER

#### Tiling the Classroom

Students see how to identify regular polygons, how to slide, turn and flip polygons, and why certain polygons tessellate better than others. Groups create a one foot square design to be used to tile the classroom. Great lesson!

Lesson Planet: Curated OER

#### Transformations - Rotations in the Coordinate Plane

In this geometry lesson plan, math scholars brainstorm examples of rotations.Â Using the SMARTboard, students observe a rotation. They create their own rotation using graph paper. Finally, pupils complete a worksheet and graph rotations.

Lesson Planet: Curated OER

#### Visual Patterns in Tessellations

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Lesson Planet: Curated OER

#### The Shape Show

Define plane shapes by their properties, then use this game to reinforce those skills. Learners use given properties as clues to determine each shape. They work to name ten different shapes, six of which are polygons.

Lesson Planet: Curated OER

#### Year 5 Unit 2b

This slide-show is packed with information relating to a variety of mathematical concepts. Intended as an accompaniment to a full unit, this resource provides definitions, explanations, and opportunities for learners to practice their...

Lesson Planet: Curated OER

#### Classifying Polygons

A straight edge, a right angle, a number of vertices; sounds like it's time to classify polygons. That's right you and your class will learn all about the properties of polygons and how to classify them with this easy to follow...

Lesson Planet: Curated OER

#### 2D Shapes

This engaging presentation would be helpful for your young learners of geometry. Pupils are given clues as to what a shape may be, then they have to use those clues to guess what shape is being described. Shapes used are the circle,...

Lesson Planet: Curated OER

#### Measures Combined

Use this resource to teach perimeter of regular plane shapes, measurement, rounding, and systematic problem solving skills. There are 78 complete slides and two game suggestions intended to facilitate content understanding.

Lesson Planet: Curated OER

#### Year 5 Unit D1

This presentation is intended to accompany an entire unit and covers a wide variety of concepts. Counting on, counting back, symmetry, properties of 2-D shapes, completing symmetrical patterns, and measuring angles are all covered.

Lesson Planet: Curated OER

#### Building Big and Strong

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Lesson Planet: Curated OER

#### Poly-Mania

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Lesson Planet: Curated OER

#### Calculating and Measuring Perimeters of Polygons

If you're teaching 3rd or 4th grade math, this presentation is a must have. It defines perimeter and polygons, then describes the process by which perimeter is determined through pair share discussion and critical thinking questions....

Lesson Planet: 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...

Lesson Planet: Curated OER

#### Create, Classify, and Sort Quadrilaterals

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes suchÂ as angle size and presence of parallel sides. As a result they learn to differentiate among rectangles,...
