Check out this wonderful work from Rosanne Regan Hansel, Exploring the 3-D World.
New brain research and child development studies are filling professional journals with mounting evidence that early childhood educators need to start paying greater attention to developing children’s spatial skills, which includes navigating that three-dimensional world and interacting with three-dimensional materials.
Having good spatial skills strongly predicts children’s future achievement in STEM subjects. Spatial reasoning is also integral to everyday life, in social studies, the arts, and geography as well as new careers like computer animation.
Working in 3-dimensions doesn’t happen as often in the early childhood classroom. Many teachers focus on 2-dimensional mediums for children to express their learning. This book will help teachers feel confident in implementing more mathematical concepts into their rooms.
