As a class, we discussed and made a chart of different types of lines. Lines like wavy, curved, zig-zag and many more. Students then used a big crayon to practice some lines on a piece of paper. They could use as many lines as they wanted, but the lines had to go from one side of their paper to the other.
The next Art day, we used tempera paint to color in between the lines. This helped students practice brush control. I was very impressed with how some of these came out!
