How to Measure Length with Non-Standard Units

Scratch Garden

This engaging animated video introduces early learners to the fundamental concepts of measuring length using non-standard units. Hosted by a humorous red oval character, the lesson breaks down the definition of length as the distance between two points and distinguishes between standard units (like inches) and non-standard units (like paperclips or the video's chosen unit, salamanders). The video uses comedy and clear visuals to make abstract measurement concepts concrete and accessible for young students. A central feature of the video is the segment on "The Important Rules for Measuring," which explicitly teaches the procedural requirements for accurate measurement: using identical units, ensuring units touch without gaps or overlaps, measuring in a straight line, and measuring from start point to end point. These rules address common errors young children make when learning to measure, providing a strong pedagogical foundation. The video applies these rules through a fun scenario involving three cows wearing silly hats. Students practice counting units to determine height and width, and then use those numbers to compare sizes using vocabulary like "taller," "shorter," and "widest." This resource is an excellent tool for introducing measurement standards, reinforcing counting skills, and bridging the gap between direct comparison and using formal rulers.
