Overview
Geometry is all about shapes and figures around us. In this chapter, we learn about different types of lines, 2-D and 3-D shapes, and fun activities like making shapes by folding paper and solving tangram puzzles. We also explore patterns called tessellations and learn how to read simple maps using
Key Concepts
A straight line goes in one
A straight line goes in one direction and is the shortest path between two points. A curved line bends and can be seen in shapes like circles and oval
Flat shapes like triangles
Flat shapes like triangles, squares, and circles that have only length and width. They have sides and corners (vertices).
Solid shapes like cubes
Solid shapes like cubes, cylinders, and spheres that have length, width, and height. They have faces, edges, and vertices.
A Chinese puzzle made of seven
A Chinese puzzle made of seven flat pieces (tans) that can be arranged to form different shapes like animals, houses, and letters.
Patterns made by repeating a shape
Patterns made by repeating a shape without any gaps or overlaps, like tiles on a floor or a honeycomb.
Learning Objectives
- Identify and differentiate between straight and curved lines.
- Recognize and describe 2-D shapes like triangles, squares, rectangles, circles, ovals, and hexagons.
- Understand the properties of 3-D shapes such as cubes, cuboids, cylinders, cones, and spheres.
- Learn about faces, edges, and vertices of 3-D shapes.
- Create shapes by paper folding and understand how 2-D nets form 3-D solids.
