Objective:

In this lesson, we will learn about 2D shapes and explore their properties.

Warm up Activity:

Let's start with a fun warm-up activity to get us thinking about shapes!

• Can you count how many shapes you can find in our classroom?
• How many shapes can you count on your way to school/home?
• Can you name any of the shapes you see?

Main Activity:

Now that we have warmed up let's start exploring 2D shapes! We will start by discussing what a 2D shape is and how it is different from a 3D shape. Let's look at some examples of 2D shapes like circles, squares, triangles, rectangles, and diamonds.

Circle:

• A circle is a shape that is round like a ball or a tire.
• It has no corners or edges.

Square:

• A square is a shape with four equal sides and four corners.
• All angles in a square are right angles.

Triangle:

• A triangle is a shape with three sides and three corners.
• The corners are called vertices.
• Triangles can be different shapes and sizes.

Rectangle:

• A rectangle is a shape with four sides and four right angles.
• The opposite sides of a rectangle are equal and parallel.

Diamond:

• A diamond is a shape with four sides that are all the same length.
• It looks like two triangles stuck together.

Conclusion:

Great job! You learned all about 2D shapes and their properties. Next time you see any of these 2D shapes, you can identify them easily!
