Keep the first session small.
Choose a repeatable slot, such as twenty minutes after school. Keep a notebook and pencil ready. Define a small task before starting: one object, one scene or one visual story. Finishing a simple exercise creates a better routine than waiting for an impressive idea.
Exercise 1: one object, five views.
Choose a bottle, shoe or kitchen utensil. Draw it from different viewpoints. Notice how the visible surfaces and proportions change. Use light construction lines and compare each drawing with the real object before adding detail.
Exercise 2: a story in four frames.
Illustrate a familiar activity, such as missing a bus or making tea. Try to make the action understandable without dialogue. Focus on the sequence, the viewpoint and the most useful information in each frame.
Exercise 3: improve a small experience.
Observe a minor inconvenience: tangled cables, an awkward lunchbox or a confusing sign. Sketch three possible improvements. Add a short note describing who each idea helps and what trade-off it makes.
Exercises 4 and 5: memory and alternatives.
Look at a scene for a short time, put it aside and sketch what you remember. Then check what you missed. On another day, take an ordinary object and imagine three different uses. These exercises invite close observation and flexible thinking; they are practice prompts, not official examination tasks.
End with one useful note.
Write what worked and one thing to try next time. Avoid judging every page as good or bad. A sketchbook is a place to develop thinking, so unfinished experiments belong there too.
