What educators are saying

This was a very engaging resource that also helps to engage higher-order thinking. My students enjoyed being able to discuss the problem, find the error, and then complete the problem correctly.
I've used this both online and in person over the past two years. It's a good extension of student learning.

Description

EQUATIONS & INEQUALITIES - Error Analysis

Have your students apply their understanding of EQUATIONS & INEQUALITIES 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.

Print or Digital: (updated March 2021)

✔️ PRINTED VERSION - a PDF file that you may PRINT

✔️ DIGITAL VERSION (Easel by TpT) - There is also a digital version using TpT's new digital tool. After purchase, click the "Open in Easel" button. This will give you access to a version with text boxes for student input and moveable shapes for students to select answers. You can edit the digital overlay or use it as is.

What is Included:

This resource includes 10 real-world EQUATIONS & INEQUALITIES 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:

✔ addition and subtraction equations

✔ multiplication and division equations

✔ two-step equations

✔ addition and subtraction inequalities

✔ multiplication and division inequalities

✔ two-step inequalities

Common Core Aligned:

*7.EE.3 - Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically.

*7.EE.4 - Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
Solve word problems leading to equations of the form 𝘱𝘹 + 𝘲 = 𝘳 and 𝘱(𝘹 + 𝘲) = 𝘳, where 𝘱, 𝘲, and 𝘳 are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?
Solve word problems leading to inequalities of the form 𝘱𝘹 + 𝘲 > 𝘳 or 𝘱𝘹 + 𝘲 < 𝘳, where 𝘱, 𝘲, and 𝘳 are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.
