Engage your students with 6 Error Analysis worksheets for adding and subtracting decimals. I began creating Error Analysis sheets for my students after reading about Marzano’s New Taxonomy, or Systems of Knowledge. Under Analysis, he lists Error Analysis as an exceptional to promote thinking and learning.
Digital Access: This resource now includes Digital Access via Google Slides.
My students LOVE error analysis, and I have even seen kids take error analyses out to recess because they are determined the figure out what error took place, or the perfect wording to describe what happened. Some of these are tricky, but the kids get a sense of satisfaction out of figuring out what went wrong!
Answer keys with POSSIBLE answers have been included, and Analysis #7 was left blank for you to create your own based on errors students in your class are making. You can use these as warm ups with the whole class, as an assessment, math centers, or enrichment for early finishers! Have fun!
