One of my favorite activities to use during math instruction involves math error analysis. I love having my students dig deeper into a concept or skill by analyzing, identifying, and explaining errors. In this post, I will touch on a few benefits to using math error analysis tasks and then some ideas for how to easily implement these types of tasks in your classroom.
Let’s begin with the why it is a good idea to have students analyze math errors.
- It promotes higher level thinking. According to Robert Marzano, error analysis is at the top of the higher level thinking skills. It requires students to create, analyze, and even prove their claim.
- It aids in conceptual understanding. The tricky part of having students do traditional algorithms is they sometimes lose the conceptual reasoning behind the steps. When students can find errors in a process and explain it (that part is key), they are really showing a conceptual understanding of the skill or concept.
- It is a great test taking strategy. Let’s face it, tests are here to stay. Teaching students to find errors in thinking and algorithms is a perfect way to prepare them for multiple choice math questions in an authentic manner. When they solve a math problem and are unable to locate the answer in the choice, they can look over their work and see if they can determine the error in their own math.
Now, that we know why we should be having students analyze math errors and participate in error analysis tasks, let’s talk about how you can implement this in your classroom immediately.
- Have the students determine the errors in their own math work on assessments. Instead of just handing back assessments and having the students correct their work, have them analyze their own errors and explain them.
- Create a gallery walk with posted errors on chart paper. Use your students’ own errors to create anchor charts with problems showing that error. Have the students walk around the room examining the error analysis tasks and discussing them with partners. Read a bit more about how I use a gallery walk activity in math here.
- Implement error analysis math tasks into your review or math centers. Have your students regularly practice analyzing math errors as part of their normal math center or independent work.
I believe in this type of instruction so much that my freebie for you today is a free pack of error analysis math tasks. These are ten different tasks that come from my 4th Grade and 5th Grade Math Error Analysis Tasks. (Note: FREE tasks are not the exact tasks shown.) These tasks are standards based (with the standard easily labeled in the corner) and the complete set includes a few tasks per standard for lots of practice. The tasks all follow the same format: a task is shown with the student’s answer as well as their work or thinking. The student must identify the error that was made and explain why they think the student made the error. Then, the students solve the problem or task correctly and explain their thinking. Take a peek at a few examples.
I am loving all that writing that goes along with these tasks. These type of tasks are also perfect for improving your students use of math language. The tasks allow you to see where your students are in their current abilities to write about math. You can plan further instruction based on that.
