To start off this first grade lesson and ingrain my students' brains with the rainbow color order one more time- students used the stick on paper tape to create part of a rainbow.
(If you've never used, it's great for the little ones especially.)
Then we read A Color of His Own and each student drew a
chameleon at the bottom of the page with a place.
The students colored in the chameleons in rainbow order to match their rainbows using twistables.
The final touch was painting with watercolor to fill in the rest of the rainbow.
It was a great practice for beginning watercolor use as well.
