This is a choice board consisting of three difficult, three medium and three easier questions. Most of them combine decimals, fractions and percents. Students are given a choice of problems, as long as they try at least 9 points. They may try more for extra credit (at teacher's discretion, of course). Students are expected to show and explain the work neatly for full credit. This can be used as a project and/or assessment, or even a partner activity.
