CONTENT OF THE LESSON

INTRODUCTION

Scratch is not only used for creating games and animations; it can also be used to draw pictures and geometric shapes. By using the Pen Extension and motion blocks, a sprite can draw lines and shapes by following programmed instructions.

In this lesson, pupils will learn how to use Scratch to draw simple shapes such as squares, rectangles, triangles, and circles, helping them develop creativity, logical thinking, and problem-solving skills.

LESSON 1 – MEANING OF DRAWING IN SCRATCH

Drawing in Scratch is the process of using Scratch programming blocks and the Pen Extension to create lines, shapes, and simple pictures on the Stage. The sprite follows the instructions written with programming blocks to draw different objects automatically.

Drawing in Scratch helps pupils develop creativity, logical thinking, and programming skills.

THE PEN EXTENSION IN SCRATCH

The Pen Extension is a Scratch feature that enables a sprite to draw on the Stage as it moves.

Some common Pen blocks include:

1. Erase All – Clears all drawings on the Stage.

2. Pen Down – Starts drawing as the sprite moves.

3. Pen Up – Stops drawing.

4. Set Pen Colour – Changes the pen colour.

5. Set Pen Size – Changes the thickness of the pen.

STEPS FOR DRAWING BASIC SHAPES IN SCRATCH

1. Open Scratch 3.0.

2. Create a new project.

3. Click the Extensions button.

4. Select the Pen Extension.

5. Add the Erase All block.

6. Add the Pen Down block.

7. Use Move and Turn blocks to draw the required shape.

8. Add the Pen Up block after completing the drawing.

9. Click the Green Flag to run the program.

LESSON 2 – BASIC SHAPES THAT CAN BE DRAWN IN SCRATCH

1. Square

A square has:

• Four equal sides.

• Four right angles.

The sprite moves forward and turns 90° four times.

2. Rectangle

A rectangle has:

• Two long sides.

• Two short sides.

• Four right angles.

The sprite moves different distances and turns 90° at each corner.

3. Triangle

A triangle has:

• Three sides.

• Three angles.

The sprite moves forward and turns 120° three times to draw an equilateral triangle.

4. Circle

A circle can be created by using many small Move and Turn blocks repeatedly to form a curved shape.

IMPORTANCE OF DRAWING IN SCRATCH

Drawing in Scratch helps pupils:

1. To learn programming through practical activities.

2. To develop logical thinking skills.

3. To improve creativity and imagination.

4. To understand shapes and angles.

5. To build problem-solving skills.
