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.

- Use the four operations with whole numbers to solve problems.[4]
- 2. Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.[4]
- Ratios and Proportional Relationships[6 - 7]
- Understand ratio concepts and use ratio reasoning to solve problems.[6]
- 1. Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak." "For every vote candidate A received, candidate C received nearly three votes."[6]

  nice for self-directed learner

- 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.
