Select one of the two subjects, then either 4th grade or 8th grade, and the number of questions asked. The questions are from The Third International Mathematics and Science Study (TIMSS) conducted in 1999, which collected data in 38 countries to provide information about mathematics and science achievement of U.S. students compared to those in other nations. From the Explore Your Knowledge home page, click on the graphic of the frog for a fun data-gathering activity.
