Thinking Blocks is a series of free, multimedia math programs that teach students how to model and solve multistep word problems. Using a combination of guided practice, video instruction, and assessment, Thinking Blocks encourages students to discover the concepts and relationships that are at the core of every math problem. Practice sets include addition and subtraction, multiplication and division, and ratio and proportion.
