• Lightbulb The ratios used in this standard will compare like units, and students may be exposed to a number of ways to show ratios. For example, students may be given a part to whole relationship (7 boys in a class of 18 students) or a part to part relationship (11 girls and 7 boys in a class). Students need to practice with both in order to master this standard. Sometimes the multiplicative part will be included like Scott is twice as tall as Lexi. Exposing students to a variety of problem types will help them master this standard.
