This lesson incorporates both computer science and mathematics to analyze coding with patterns and proportional relationships. It uses the Turtle library with Python programming.

Students lean about proportions, ratios, and unit rate. It is important for connections to be made among ratio tables, graphing points, and slope of a line. Students make these connections through the first activity provided by the VDOE. The second task by Illustrative Mathematics is a way to assess student understanding.

This activity asks students to use proportions to find a missing unit cost or unit weight for various amounts of fruit. This should be used as practice after students have a solid understanding of how to use a proportion to find a missing value.

Video Description:  How does NASA test ideas, like the Mars Helicopter, before they are even built? Find out more about this revolutionary helicopter and how NASA uses mathematical modeling to turn complex ideas into solvable equations that help shape future missions. Video Length:  3:20.NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.

Students use concrete objects, representation, and abstract (algorithmic) thinking to complete 3 percentage word problems. The CRA assessment provides teachers with a deeper understanding of students' thinking. Do your students understand the relationship between the proportional algorithm and proportional reasoning?
