This is a great lesson to introduce "line design" to 1st graders. The book Lines that Wiggle is a great complement to this lesson. We used 12 x 18 yellow paper and a large tracer for the leaf. Crayons were used to add line designs and the painting was done with cotton swabs to create a small dot pattern. Using old egg cartons to hold the paint makes clean up easy peasy! (See pics below) My favorite is the gold paint because it adds a bit of shimmer to the lovely leaves! it was a kid favorite too!
