Feel free to re watch that video from Monday and don't be shy to offer it as a choice.
If the children are engaged in the work offered in this video, encourage them to take their time and pause the video so they don't feel rushed.
Gather some materials, including paper and writing tools in the video, (Greg used crayons as his writing tools but whatever you have handy should work.)
Have fun and take your time. This experience is designed to engage at a leisurely pace or to be be revisited. If the children want to move on, keep this possibility in your back pocket as an option down the road.
If you take any pictures you want to share of the children watching the video or working on the color taming project feel free to share them with Greg!
