Figure This - Math Challenges for Families

Figure This is a website produced by the National Council of Teachers of Mathematics. The site presents viewers with a series of math problems designed to spark discussion and collaboration between parents and their children. The problems are based around objects and situations with which most students will be familiar. For example, there are questions about how movies make money, how far a paper airplane can fly, and when to buy block ice instead of crushed ice.

Applications for Education
Figure This could be a good resource for mathematics problems that you can send home with your elementary school students to discuss with their parents. Some of the challenges include a physical element that could be used in a fun classroom lesson.
