The First Drawing by Mordicai Gerstein asks your child to imagine if they were the first person to invent drawing, way back when the woolly mammoths walked the Earth. A wonderful concept with great execution.
My second-born has always been highly imaginative and sees faces in the ceiling, so he connected with The First Drawing.
If you live near the North Carolina Museum of Natural Sciences, get your hands on this book now and then attend their PaleoPalooza event (This year it's Nov 14th, 2016)! Last year they had a display talking about Lascaux Cave in France, as well as an area where kids could make their own 'cave drawing.' Perfect!
Also worth mentioning:
Mordicai Gerstein also wrote How to Bicycle to the Moon to Plant Sunflowers: A Simple but Brilliant Plan in 24 Easy Steps. (You can take a breath now!) This book is as silly as it sounds and my kids laughed every single time we read it.
