RATIONAL NUMBERS (Fractions and Decimals) Error Analysis (Find the Error)
Have your students apply their understanding of RATIONAL NUMBERS 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 RATIONAL NUMBERS 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:
✔ adding, subtracting, multiplying, dividing positive and negative FRACTIONS
✔ adding, subtracting, multiplying, dividing positive and negatives DECIMALS

Common Core Alignment :
*7.NS.1 -Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers;
*7.NS.2 - Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
*7.NS.3 - Solve real-world and mathematical problems involving the four operations with rational numbers.
*Mathematics Practice Standard 3 (construct viable arguments and critique the reasoning of others).

FEEDBACK on this resource:
♥ My students loved this activity. Created such good discussions between my students.

♥ Love these, great for stations!

♥ One of the things my students struggle with most is identifying the error(s) in their own or someone else's work. This provides great practice on that skill.

♥ Great for higher level thinking! Thanks!
