EXPLORE YOUR KNOWLEDGE
http://nces.ed.gov/nceskids/eyk/
Compare your mathematics and science knowledge with that of
4th or 8th grade students from countries around the world
using Explore Your Knowledge, a feature of the National
Center for Education Statistics (NCES) Students' Classroom
site.
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.
