Estimating with Non-Standard Units Answer Key

This worksheet challenges students to choose the best estimate for how long each object is using non-standard units such as paperclips, hand spans, toy cars, and blocks. Learners must read each question carefully and select the most reasonable option from multiple choices. This activity promotes estimation, reasoning, and comparison skills while reinforcing measurement vocabulary. By determining appropriate lengths for familiar objects, students gain a stronger understanding of scale and develop their ability to approximate using indirect units. It also supports decision-making and number sense related to size and proportion.
