Are you tired of seeing your students make the SAME MISTAKES over and over when they're adding tenths and hundredths? Try giving them something challenging and interesting like these error analysis problems. Students love to find errors in work - as long as it's not their own!
Error analysis problems are a great way to check your students' understanding of a concept. Instead of just solving the same problems again and again on a worksheet, they have to use their critical thinking skills to determine where, if anywhere, the example student(s) went wrong. This forces them to think outside of the box and develop a deeper understanding of the WHY behind the procedures and processes.
This download includes eight error analysis problems (two per page) that practice adding tenths and hundredths as fractions. While the problems primarily focus on adding the fractions, students may need to subtract that total from a whole (10/10 or 100/100) to get their final answer.
On my answer key, I have provided an example of a student response, but other answers may be acceptable as well.
Looking to save paper? The last page of work contains the same 8 questions on one piece of paper – great for task cards or gluing into notebooks!
This product perfectly aligns with 4th grade Common Core standard: 4.NF.C.5: Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.
These tasks would be great to use during guided math centers, whole-group centers, or independent practice.
