Lesson summary

Welcome, learners! Before a carpenter builds a beautiful chair, a tailor sews a stylish dress, or an engineer constructs a strong bridge, they must first have a clear plan. This plan is a drawing. Drawing is the language used by designers, makers, and builders to share their ideas accurately. If the plan is wrong, the final product will be wrong, wasting time and precious materials. In this lesson, we will learn about the basic tools that help us create these important drawings. Understanding these tools is the first step to bringing your own creative ideas to life, whether you want to design a new school bag, a small house, or a piece of art.

Lesson notes

To communicate our design ideas clearly, we use special tools. We can group these tools into three main categories: Drawing Materials: These are the items that we draw *on* or draw *with*, and they are often used up or consumed in the process. Think of them as the supplies. Drawing Instruments: These are the tools that help us draw accurately. They guide our hands to make straight lines, perfect circles, and precise angles. They are not used up. Drawing Equipment: These are the larger items that support the drawing process. They provide the surface and stability needed for good technical drawing.

Let's look at the most important items in each category. Category 1: Drawing Materials

These are the consumables used in drawing.

| Material | Description | Main Use / Function | Ghanaian Context Example | | :--- | :--- | :--- | :--- | | Drawing Paper | A smooth, usually white or off-white sheet of paper. Comes in different sizes (A4, A3, etc.) and thicknesses. | It is the surface on which the final drawing is made. | An architecture student at KNUST uses an A3 sheet to draw the plan for a new classroom block. | | Pencil | A tool made of graphite inside a wooden case. Pencils come in different grades of hardness (e.g., H, HB, B). | Used for making lines and sketches. Harder pencils (like 2H) make light lines for construction, while softer pencils (like 2B) make dark lines for outlining. | A student in your class uses an HB pencil for everyday writing and drawing in their notebook. | | Eraser | A small block of rubber or plastic. | Used to remove unwanted pencil marks or mistakes from the drawing paper without damaging the paper's surface. | When drawing a map of your school, you use an eraser to correct the position of the football field. | | Tracing Paper | A thin, translucent (see-through) paper. | Used to copy an existing drawing by placing it over the original and tracing the lines. | A seamstress like Auntie Mercy might use it to copy a dress pattern from a fashion magazine. | | Masking Tape | A paper-based tape with a gentle adhesive. | Used to hold the drawing paper securely onto the drawing board so it doesn't move while you are drawing. | To keep your drawing of a hoe steady, you tape the four corners of the paper to the board. | Category 2: Drawing Instruments
