The information provided is not limited to mathematics. Look at California's standards and compare those to the NCTM standards. This website at Harvard University focuses on the assessment of rich, mathematically complex work. Select one of the sample assessment tasks for the elementary grades and analyze it in terms of what you have learned in this chapter. This website provides a collection of problems suitable for grades 3-6.
Students have access to the solutions.
The problems involve a variety of mathematical topics and tend to be routine problems. Students can e-mail solutions to Mr. Finch's class. Bookmark this site and have your students try some of the problems. Some are simple and make good warm-up activities. Others involve substantial problem solving.
