Have your students apply their understanding of EXPRESSIONS with this ERROR ANALYSIS activities.
Benefits of Math Error Analysis: Giving students opportunities to identify and correct errors in presented solutions allows them to show their understanding of the mathematical concepts you have taught.
Whats Included: This resource includes 10 real-world EXPRESSIONS word problems that are solved incorrectly. Students have to IDENTIFY THE ERROR, provide the CORRECT SOLUTION and share a helpful STRATEGY for solving the problem. An ANSWER KEY has also been provided with examples of possible answers. Be sure to download the sample for a full overview of what you get.
How to Use: When I present this activity to my students, I tell them that these are errors that students from my other class made and I need their help to correct them. Students LOVE correcting other students mistakes. Students can use these activities with a partner, as a warm-up , as classwork, homework, in math centers or group work.
Topics included: ✔ evaluating algebraic expressions
✔ writing algebraic expressions
✔ simplifying algebraic expressions
✔ adding linear expressions
