Dooby, Dooby, Moo: No Average Math Book

This ain't no average averaging.

We LOVE the book Dooby, Dooby, Moo by Doreen Cronin and Betsy Lewin and regularly giggle over the eccentric group of farm animals who take their talents to the county fair to compete. Throughout the story, illustrations show the animals receiving scores for their performances. For example, when the cows sing "Twinkle, Twinkle, Little Star"* they receive the following ratings:

8 (from a human judge)
8.2 (from a dog)
2 (from a man)
1.2 (from a grumpy-looking cat)

What an opportunity to do a little averaging! During the sheeps' rendition of "Home on the Range," it notes that "Three of the [four] judges were clearly impressed." Scores of  9, 9.1, and 8.9 are followed by the cat's score, 2.3, providing an opportunity to talk about outliers!

This is no average math lesson! For more children's lit/math books, see THE LIST.

*"Dooby, dooby, dooby moo. Dooby moo, moo, moo, moo, moo." My kids think it's hilarious when I sing this!

If you're interested in purchasing the book through Amazon, all commissions go toward foster care in China through Grace and Hope at no additional cost to you.
