The information in this book can be useful but it would be better if it weren't so drawn out. Lots of busy work, lots of space to draw. Would have been a better book if it focused on a concept & was concise. It is thicker than it needs to be with lots of filler. It would be better if a concept were presented clearly and had an activity to illustrate it, rather than a jumble of stuff. It does not invite a child to want to read it, it's overwhelming.
