In this lesson, students will learn how to identify and classify geometric figures in two-dimensional shapes. They will understand the properties of points, lines, rays, and angles and use them to analyze shapes. By recognizing parallel...

Mr. Addit reviews two-dimensional plane shapes and introduces three-dimensional shapes and discusses their attributes.

Two-dimensional figures and polygons.

Two-dimensional figures and polygons.

Introducing angles in two-dimensional figures.

In this lesson you will learn how to determine whether two dimensional shapes are similar by testing whether the shapes have the same number of sides, the same ratio between dimensions, and the same ratio within dimensions.

Andy and his class are going for a field trip to Geometry town. The teacher gave them an interesting task, they should look all around geometry town, and try to figure out the different geometrical shapes they’ve seen and learned at school.

We have 3D + 1D of time. Why aren’t there 4 dimensions or 2 dimensions? Can life exist in the 4th dimension? Is there something special about three dimensions that makes life possible? This is the question that But...

Using the drawings in her sketchpad and some graphics, Miss Palomine demonstrates to the student, the similarities and differences between two-dimensional and three-dimensional shapes.

Identify points, line segments, rays and lines in two-dimensional figures.

In this video, students are taught how to draw shapes with a specific number of angles at the Shape Workshop. The lesson explains the concept of polygons and two-dimensional shapes, and demonstrates how to construct shapes with different...

The video is a tutorial on how to draw and understand basic two-dimensional and three-dimensional shapes, including squares, triangles, circles, cubes, cones, spheres, cylinders, and hemispheres. The shapes are demonstrated step-by-step...

Miss Palomine reviews two-dimensional and three-dimensional objects. She then looks for matching two-dimensional objects in her environment and afterward, searches for three-dimensional objects.

This video, entitled "Two-Dimensional Figures," explains how to transform two-dimensional figures.

Cross sections are an important mathematical concept; however, cross sections are also used throughout the world around you. Dig a little deeper to understand cross sections and identify the two-dimensional shapes formed with a cross...

This programme introduces the properties of two-dimensional three and four sided shapes and is split into three sections: In the case of the disappearing shapes an animated sequence takes a look at how the world would be without four...

In this video, the teacher explains how to determine the shape of a cross section when slicing a three-dimensional solid. By analyzing whether the slicing plane intersects with straight or curved surfaces, students can visualize and...

In this video, the teacher explains how to visualize and identify the two-dimensional cross-sections of cones. They discuss the different shapes that result from slicing through cones at different angles, such as triangles, parabolas,...

Mr. Addit reviews two and three dimensional figures.

Pupil outcome: I can investigate how polygons can be joined and folded to form 3D shapes. Key learning points: - 3D shapes can have flat faces. Each face is a 2D shape. - 2D shapes can be folded and joined together to build 3D shapes.

This video discusses the basic terms and characteristics of solids, and demonstrates how different slicing angles result in different shapes. The teacher also highlights the relationship between the number of faces and the maximum number...

In this lesson, students will learn how to find the volume of geometric solids by using their knowledge of two and three-dimensional shapes, as well as the measures of area and perimeter. They will understand that volume refers to the...

In this video, students will learn how to predict the three-dimensional shape that results from rotating a two-dimensional figure. By analyzing the effects of rotations and understanding the concept of an axis of rotation, they will be...

In this video, students will learn how to describe the cross-sections of a right rectangular prism by slicing at different angles. They will understand the concept of cross-sections as the two-dimensional shape that results from cutting...
