## The Book

Have you ever read One Grain Of Rice: A Mathematical Folktale by Demi? Not only is it great literature, there is a fantastic moral to the story – and a mathematical component that makes for a fun living math lesson! The story is set in India where a raja decides to store his people’s rice so they will have plenty in time of famine. When famine arrives, the raja becomes selfish and holds the rice for himself – leaving his people to starve. A clever young girl devises a plan that starts with only one grain of rice which will double daily – quickly growing into a mountain of rice that easily feeds the people. Through her wisdom, the raja is humbled and promises to live a fair life once again.

## The Math Activity

**I found the math activities and GREAT worksheets at the NCTM Illuminations site. There are many super activity ideas there, so hang around a while.*

After reading the story, Mahayla (5th grade) had to chart the number of grains of rice the raja gave away each day and in total. Since the numbers became huge, I let her use a calculator.

Next, she had to determine how many cups of rice were given away on a few of the days, as well as the weight of the rice and number of people it would feed. I loved this extension!

Fun math, a great book with a moral, real-world type stuff, and lots of computation! Who could ask for more in a math activity?
