Thinking Blocks: Ratios

This set of six interactive Flash activities gives students an opportunity to visually model and calculate the unknown quantity from ratios and other information, all in the context of solving word problems. A video demonstration introduces each method, and then students work on modeling and solving five problems. Students can check their modeling of the problem at intermediate stages. Teachers can track a student's progress throughout the problem set.

    • A very comprehensive interactivity intended to help students extract information from word problems, build a visual model and use it to solve. Many types of ratio problems and representations are included. There is an introductory video and a progress tracker for the instructor. A good quantity and variety of problems are available.

      Amazing info

    • I actually never understand these number senses because I never take interest in it. However, this article conditionally made interest in my mind and now I am a person which greater basic skills of mathematics and cheap assignment writing service provides good stuff. All thanks to “Colleen King” who faced efforts to make this unique idea.
