Professional Commentary

Entries on the Ohio Resource Center Mathematics Bookshelf, the books One Grain of Rice and The King's Chessboard tell the same classic tale of the astounding effect of doubling a single grain of rice each day over a period of 30 days. In The King's Chessboard the protagonist is a wise man and the quantity of rice is analyzed in terms of weight. In One Grain of Rice the protagonist is a young girl and the quantity of rice is analyzed in terms of the number of grains. Both books are beautifully illustrated. (sw)

Patterns, Functions and Algebra Standard
Benchmarks (5–7)
L.
Analyze functional relationships, and explain how a change in one quantity results in a change in the other.
Benchmarks (8–10)
D.
Use algebraic representations, such as tables, graphs, expressions, functions and inequalities, to model and solve problem situations.
