This activity is designed to help students identify (and avoid) common errors made when solving Linear Inequalities . It also gets students to work cooperatively.
Students are given 7 situations, each with 2 suggested solutions. Only one of the answers is correct and differs from the other by a characteristic, that identifies a specific (single) rule (ex.: the sign indicates the upward shading vs. downward shading). Students need to identify that rule and communicate it in writing.
This activity is designed to address students’ ability to choose a strategy, develop a logical argument and draw conclusions based on their observations.
This item includes: 14 problems (7 pairs) on 2 student pages, which allows you to save paper!), 2 key pages, 1 page of teacher’s instructions. Total of 5 pgs (does not include the cover sheet). Possible Uses:
- Follow-up after the 1st Linear Inequalities lesson;
- Group work
- End of Lesson Check for understanding;
- Reteaching replacement/ Topic Review;
