Description
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;
- Test Prep.

Loved the error analysis!
Students loved this, great review!
Can't wait to use!!!
LOVE
LOVE your comment, April!
I love how this gets students really thinking about the reasoning behind their decisions!
Thank you, Emily, for finding time to write this comment.
I am glad your students were "tricked" into talking about the reasons behind their mathematical decision making.
Great activity!
Thank you, Shawna, for finding the opportunity to share feedback about this "reasoning with Math" activity.

CCSSHSA-REI.D.12
Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.
CCSSMP1
Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
CCSSMP2
Reason abstractly and quantitatively. Mathematically proficient students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize-to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents-and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved. Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects.
