Great Estimations

Great Estimations by Bruce Goldstone, 2006 is an educational book for elementary age children. It gives a step by step method for developing the skill of estimation. To begin, the book has a picture of objects in groups of tens. The author encourages children to train their eyes to see and estimate what a group of ten objects looks like. Then the author tries to show groups of 100, then 1,000, etc.

In addition to eye training, the author uses clump counting, box & count, and greater estimation methods by using objects like cheerios, macarroni noodles, acorns, etc.

If you practice your estimation skills, you will get better and better at counting estimation and measuring estimation.

I think this is a great book for elementary age children and a great book to spark summertime learning activities. I think about how many times I have to give an estimation of the number of people in attendance at a given event or the number of fireflies I saw light up a summer evening sky, or even how many feet away the deer were from my car! This is one math lesson that your child will use far beyond his/her school years!
