Variables+and+Patterns+0910

Welcome to the seventh grade math (section 7D, 2009-10) class wiki at the American International School of Dhaka.  

Variables and Patterns
Big Idea:Observation and description of changes in the world around us are the first steps in finding and learning about patterns.
