We did warm-up practice sheets using two random pick colored pencils taped together so that one pencil sticks out a bit beyond the other. This gives practice in seeing what strokes a flat edge tool makes.
Then we drew in a similar way using a broken crayon, peeled and flat against the paper. One can make fat and thin strokes and strokes that change widths depending on their angle against the paper. After trying the May basket drawing in one color we made another drawing with several colors.
The lesson was the same for both classes.
