About This Chapter
Teaching Geometry Basics - Chapter Summary
In this interesting chapter, our instructors review the methods used to successfully teach the basics of geometry. You can study the definition of 2D shapes and 3D shapes as well as see examples of each. If you'd rather skip ahead to a specific topic in a video lesson rather than watch the whole video, use the video tabs feature in the Timeline. The short quiz you'll find after each lesson is a great way to confirm your comprehensions. Feel free to reach out to one of our instructors with any questions you have along the way. After completing this chapter, you should be able to:
- Identify 2D and 3d shapes
- Recognize parallel and perpendicular lines in geometric shapes
- Detail the symmetry and finding vertices in polygons
- Explain the properties of four-sided polygons
- Draw lines, rays, segments and points
- Use project ideas to teach geometry in real-world situations
1. The Progression of Geometric Thinking
Students develop their understanding of geometry in specific stages. But what are those stages, and how can teachers help move students through them? In this lesson, we'll look at the progression of geometric thinking.
2. Basic Geometry: Concepts & Terms
Geometry is the study of shapes and the space that they inhabitant. One-dimensional geometry is concerned with distance. Two-dimensional geometry is concerned with area. Three-dimensional geometry is concerned with volume.
3. Polygons: Symmetry & Vertices
In this lesson, we'll go over the basics of what polygons are, specifically focusing on symmetry in polygons and where the vertices can be found. We'll look at examples and images to examine these concepts.
4. 4-Sided Polygons
We are shaping up and talking about quadrilaterals. In this lesson, you'll learn about the different kinds of four-sided polygons and their properties. Let's see if we can keep them all straight!
5. How to Teach the Geometric Properties of Shapes
When teaching the geometric properties of shapes, it is important to be as hands-on as possible. Students will comprehend better with concrete examples.
6. Teaching Students to Compose & Decompose Geometric Shapes
Learning how to compose and decompose shapes can help students to understand more advanced geometric concepts. This lesson will help you teach students how to compose and decompose various shapes in order to determine perimeter, area, and volume.
7. Identifying Parallel Lines in Geometric Shapes
Watch this video lesson to learn how you can spot parallel lines in a rectangle, in a square, and in a parallelogram. You will learn how many pairs of parallel lines each of these shapes has.
8. Identifying Perpendicular Lines in Geometric Shapes
Do you know what a perpendicular line is? Do you know how to spot one in a geometric shape? This lesson will tell you how to spot perpendicular lines in squares, rectangles, triangles, and trapezoids.
9. Teaching Methods for Lines, Segments & Rays
This lesson discusses various strategies teachers can use to teach students how to identify lines (including parallel and perpendicular), segments, and rays. Tasks include manipulatives and visuals to keep students interested.
10. Geometry in the Real World Project Ideas
Geometry is a branch of math that lends itself nicely to project-based learning. This lesson will give teachers of different age groups ideas for how they can incorporate projects to show the relevance of geometry in the real world.
