Census in Schools—U.S. Census Bureau


2010 Census: It's About Us—Scholastic, Inc.


The 2010 Census is fast approaching! Census questionnaires will be mailed or delivered to every household in the United States in March 2010.

Scholastic, Inc. is working with the Census Bureau to produce lesson plans, maps, teaching guides, and other informational materials to help teachers and students learn about the importance of the Census. Access these materials for grades K to 12 through either link above.

The Census Bureau site also has games and quizzes for kids, and information for teens on real-world knowledge drawn from census data.

Fractions, Ratios, Proportions


Since we last featured Alan Selby's site "Appetizers and Lessons for Mathematics and Reason" in 2005, he has revised and greatly expanded the section on fractions and ratios, organizing it under these topics:

  • Fractions
  • Fractions with Units (arithmetic & algebra with units)
  • Ratios and Fractions (or ratios versus fractions)
  • Proportionality Relations Forwards and Backwards
  • Links

For all of Selby's pages on high school mathematics and calculus topics, see:
