Working on and activity book for kids

I have been drawing out some pages to an activity book for kids 5-9 abut washing their hands and getting rid of germs. There is a National day about this in October. I didn't know that. I am laying down pencil sketches and plan on working in activites such as mazes, dot-to-dot and possibly hidden picture. I will try and post some of them tomorrow.
Back to the drawing board!
