Choosing the Best Unit

In this worksheet, students determine which non-standard unit-grains of rice, toy blocks, or hand spans-makes the most sense to measure each object. By circling the appropriate unit for items such as pencils, tables, and playground slides, learners practice selecting measurement tools suited to different sizes and contexts. This task encourages reasoning about appropriateness and scale in measurement. Students strengthen their ability to apply logical thinking to real-world scenarios and build an understanding of why certain tools fit specific measurement tasks.
