In a lesson about piles and mountains, the so-called cumulus clouds should not be missing. Sometimes you see them high in the sky shining like mighty mountains. Maybe you are used to drawing a cloud like in the first example. I’ll show you in a few steps how to draw a cumulus cloud with a little shadow.
Step 1: start with just one piece of the cloud, as if it were a mountain; they are all little arcs attached to each other and certainly not too regular. Leave the bottom side open for a while.
Step 2: attach a second piece of cloud to it. Clouds are constantly changing shape, so you can too.
Step 3: make the cloud as big and extensive as you want with new pieces everywhere. Leave the bottom quite flat. This way the cloud appears to be floating in the air.
Step 4: finally, draw some shadow on the cloud. In my example the sunlight comes from the right.
Suggestion for teachers: do each step together with your pupil(s) before moving on to the next step
