Performance objectives

• Welcome, Grade 1 learners! This week, we're going on an exciting adventure to discover more about shapes! Shapes are all around us – in our homes, at school, and even in the tasty snacks we eat! Understanding shapes helps us describe the world, build things, and even solve problems. Imagine trying to build a house without knowing about rectangles or squares! Or building a rondavel with circles! Knowing about shapes is super important in South Africa, from designing our homes to understanding patterns in our traditional art. This week, we will focus on recognizing and describing 2D shapes like circles, squares, triangles, and rectangles, as well as 3D objects like cubes, spheres (like a soccer ball!), cones, and cylinders. We will also learn how to sort and group these shapes and objects.
• By the end of this week, you will be able to:
• Objective 1: Identify and name circles, squares, triangles, and rectangles (2D shapes) presented in different sizes and orientations.
• Objective 2: Identify and name cubes, spheres, cones, and cylinders (3D objects) presented in different sizes and orientations.
• Objective 3: Sort and group 2D shapes and 3D objects based on their shape.

Lesson notes

Let's dive into the world of shapes! 2D Shapes: 2D shapes are flat shapes that only have length and width. Think of them as drawings on a piece of paper.

Circle: A circle is round, like a wheel on a car or the sun. It has no sides and no corners.

Example: Think of a plate, a coin (like a R5 coin), or a round lollipop.

Square: A square has four equal sides and four corners that are all the same (right angles).

Example: Think of a face brick (many houses in South Africa are made of brick!), a tissue box, or a checkerboard.

Triangle: A triangle has three sides and three corners.

Example: Think of the roof of a house (a simple house), a slice of watermelon, or a road sign.

Rectangle: A rectangle has four sides and four corners that are all the same (right angles), but unlike a square, its opposite sides are equal.

Example: Think of a door, a book, a window, or a piece of paper. 3D Objects: 3D objects have length, width, and height. They take up space. You can hold them in your hand!

Cube: A cube has six square faces that are all the same size.

Example: Think of a dice, a sugar cube, or a Rubik's cube.

Sphere: A sphere is round like a ball. It's like a circle that's been inflated.

Example: Think of a soccer ball, a marble, or an orange.

Cone: A cone has a circular base and a pointed top.

Example: Think of an ice cream cone, a party hat, or some mountains.

Cylinder: A cylinder has two circular faces and a curved surface connecting them.

Example: Think of a can of Coke, a toilet roll, or a log of wood.

Worked example

Example 1: Identifying a Shape:

You see a flat shape with three straight sides. What shape is it?

Solution: A shape with three sides is a triangle.

Example 2: Identifying a 3D Object:

You see an object that you can hold. It has six faces, all of which are squares. What object is it?

Solution: This object is a cube.

Example 3: Sorting Shapes:

You have a collection of shapes: a circle, a square, a triangle, and a rectangle. How would you sort them?

Solution: You can sort them by the number of sides they have:

Circle: 0 sides

Triangle: 3 sides

Square: 4 sides

Rectangle: 4 sides

You can then further sort the shapes with 4 sides by saying that a square has all sides equal, and a rectangle has two pairs of equal sides.

Example 4: Describing a Shape:

Describe a square.

Solution: A square is a 2D shape. It has 4 sides, and all the sides are the same length. It also has 4 corners that are all the same.

Guided Practice (With Solutions)
