Counting Dots and Measuring Area: Rich Problems from Japan
November 2006, Volume 12, Issue 4, Page 214
A discussion of mathematics in terms of how Japanese students learn. Two rich, open-ended problems are presented; one involving patterns of dots and geometric and algebraic representations, and the other measuring the area of triangles and graphing piecewise functions. Includes sample solutions for the dot pattern activity and an activity sheet for the area and piecewise function problem.
