GEOMETRY Word Problems - Error Analysis
Have your students apply their understanding of 7th Grade GEOMETRY with these 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.
This resource includes 10 real-world GEOMETRY 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.

This resource is aligned with :
*7.G.1- Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale
* 7.G.4 - Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
* 7.G.5 - Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
* 7.G.6 - Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
*Mathematics Practice Standard 3 - Construct viable arguments and critique the reasoning of others.
