### We found 765 resources with the concept 2-d shapes

Lesson Planet

#### Kangaroo Hop

New ReviewScholars play against three other participants to show what they know about geometric figures. Starting at the beginning, kangaroos jump from shape to shape to match the figure to the displayed word and make their way to the finish line.

Lesson Planet

#### Geometry

Shape one's understanding of geometry using the resource. The sixth of seven chapters in 6th Grade Math focuses on geometry principles. Future mathematicians learn to find the area of parallelograms, trapezoids, triangles, and other...

Lesson Planet

#### My Dream Home

Dream big or go home. After analyzing a bar graph on the number of bedrooms in US homes derived from census data, scholars design their own dream homes. They cut out two-dimensional shapes from construction paper to create models of...

Lesson Planet

#### 2D and 3D Geometric Shapes

Mathematicians examine everyday objects around the classroom to categorize them as two or three-dimensional. Following a group discussion, pairs work collaboratively to identify objects. Independently, scholars complete a practice page.

Lesson Planet

#### What is a Constellation

Why do some stars in a constellation appear brighter than others? Using a get-up-and-move astronomy activity, scholars explore perspective and the appearance of constellations in the sky while developing an understanding of the...

Lesson Planet

#### Names of 2D Shapes

Two-d or not two-d? That's not really the question because the figures here are all two-dimensional. Learners identify the names of polygons, starting with triangles and ending with decagons. The video also describes circles and...

Lesson Planet

#### Nets

You've netted a great resource! Young mathematicians learn about the nets of three-dimensional solids by watching a brief video. The resource includes some test-taking tips on the topic for those studying for the GCSE.

Lesson Planet

#### Classify Two-Dimensional Shapes

Four problems make up an assessment created to test learners' knowledge of two-dimensional shapes. Mathematicians observe shapes, list their attributes, and use a Venn diagram to classify them. A brief reflection piece closes the exam.

Lesson Planet

#### Three Dimensions in Two Dimensions: Lesson

Slice up solids. A portion of a geometry playlist introduces two conventional ways to visualize 3-D figures in 2-D. The resource defines cross-sections and nets and provides examples of both.

Lesson Planet

#### Area of Composite Shapes: Lesson

To find the whole, add and subtract the pieces. A portion of a massive geometry playlist shows how to approach finding the area of a composite figure. The resource works with a couple different composite shapes to find their areas.

Lesson Planet

#### Triangle Classification

Oh triangle, where are the points that will make your type? Given a line segment, pairs determine the location of a third point to create the six different types of triangles. The teacher provides a jumping off point by leading a...

Lesson Planet

#### Shapes and Solids of Constant Width

Roll right along with an informative lesson that makes cents. Scholars learn that some shapes roll without any change in its width. The video in the Numberphile "Coins" series starts with two-dimensional figures, such as Reuleaux...

Lesson Planet

#### Slice of a Cone

No matter how you slice it, this is an unparalleled resource. Scholars consider the two-dimensional cross section that results from horizontal slices of a cone. They also investigate how the height at which the slice is made affects the...

Lesson Planet

#### Geometry: Visualize Relationships Between 2-D and 3-D Shapes

Slice and dice like a master mathematician. Scholars determine and draw three possible cross-sections of a cube. Given a solid shape removed from a three-dimensional figure, they describe two viable original figures.

Lesson Planet

#### 2D Rotations of Triangles

Where does the line of rotation need to be to get a cone? Pupils respond to three questions involving rotating a right triangle about different lines. The scholars describe the solid created along with providing details about its...

Lesson Planet

#### 2-D Rotations of Rectangles

Turn 2-D into 3-D using a simple rotation. The resource contains two questions concerning the rotation of a rectangle about the x-axis and the y-axis. Pupils identify the resulting solid and provide information about the dimensions.

#### End-of-Module Assessment Task: Grade 6 Math Module 5

Assess the class' ability to solve problems involving area, surface area, and volume with a six-question assessment that presents problems covering aspects of calculating measurements of 2-D and 3-D figures. Class members use the...

Lesson Planet

#### Seeing All Sides: Orthographic Drawing

How can your draw three-dimensional figures on paper? The lesson shows pupils how to draw orthographic projections of three-dimensional figures composed of cubes. After viewing a PowerPoint presentation, they practice this skill with...

Lesson Planet

#### Piece it Together

Score some problems all related to soccer balls. The first few problems focus on pattern blocks to see relationships between figures. More advanced problems focus on actual soccer balls, the patterns on the balls, and their volumes and...

Lesson Planet

#### Lyle's Triangles

Try five problems on triangles. Levels A and B focus on shapes that can be created from right triangles. Level C touches upon the relationship between the area of a six-pointed star and the area of each triangle of which it is composed....

Lesson Planet

#### Cubism

If cubism were a religion, would you follow it? Lower-level tasks focus primarily on counting the number cubes in a structure and relating the number to surface area. As learners progress to higher-level tasks, isometric drawings and...

Lesson Planet

#### The Shapes Song

Shapes are all around us. Learn the shapes in a video that has a catchy tune and shows shapes in the real world from triangles in a sailboat to squares in a door.

Lesson Planet

#### Symmetry

Eleven problems provide pupils the opportunity to find the lines of symmetry or identify rotational symmetry. Scholars alter designs to make them symmetrical, learn to recognize signs that are symmetrical, and identify the type of...

Lesson Planet

#### Mission: Rainforest

Young environmentally conscious mathematicians solve a variety of problems related to the central theme of uncovering illegal logging activities. They determine a base camp based on given constraints, investigate logging activities and...
