The teacher takes a crayon and draws randomly on the paper while describing their morning. Then I went in the shower. Tell them to fill their own page and to change colors frequently. The more variety of line and motion, the better. Encourage them to use the side of the crayon to make fat lines also.
Kids can fill in spaces between lines with color.
If there is extra time, have the kids narrate their morning while pointing to the lines they made on the page.
