While teaching First grade, I read this book multiple times through the year (not only because the children LOVED it). It introduces color words, days of the week, ordinal numbers on a very basic level. But more importantly it teaches a lesson of individual perception. We would discuss what each how each of the mice discovered about the "strange Something" and why they each thought it was something different. When squabbles occurred on the playground, I would reference the seven mice and ask each child what he saw/thought/felt.I recently bought 9 copies of this book to give to the Adult members of our Faith Sharing Group, because we often find ourselves at different points in our faith journey and often acknowledge that we each "know God" from our own experiences and perspective. Excellent Book!
