Needed activity books for my son's Prep class for rainy days and needed something he could complete on his own seeing as he can't read yet. The superheros attracted him straight away and after a quick explanation to him on what to do, he was off and running, matching stickers to their correct shapes. Would be easier if they made activity books for little ones with pictorial instructions. So hard when they can't read yet! But this was a great one that held his interest for more than 5 minutes!
