Do your students struggle to explain their reasoning behind word problems that involve converting units of measurement within the metric system? Are you looking for a new way for them to practice these important skills, without doing pages and pages of conversions?
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 six error analysis problems that practice converting metric units of measurement. There are two length problems, two weight problems, and two capacity problems. None of the problems involve decimals!
On my answer key, I have provided an example of a student response, but other answers may be acceptable as well.
This perfectly aligns with 4th grade Common Core standard:4.MD.1:
Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. It also works well with 5.MD.1:
Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.
These tasks would be great to use during guided math centers, whole-group centers, or independent practice.
