From United States Awesome flash-based site. Thinking Blocks is an engaging, interactive math tool developed by classroom teachers to help students learn how to solve multistep word problems. Using brightly colored blocks, students model the relationships among the components of each word problem. With the help of a virtual teacher, students walk through a simple problem solving process and arrive at a solution. When building the models, students must identify information that is given as well as information that is unknown. Identifying and solving for an unknown quantity is a key concept in algebra. Thinking Blocks encourages students to look beyond the surface to discover the concepts and relationships that are at the core of every math problem
