A culminating measurement challenge where students apply all skills to measure and compare lab 'specimens'.

Students use their measurement skills to compare two objects by measuring each with the same unit.

Students develop estimation skills by predicting how many units long an object is before measuring.

Students practice precise measurement by identifying common errors like gaps, overlaps, and crooked lines.

Students measure the same object using different units (paperclips vs. tiles) and compare the results.

Students measure objects using connecting cubes, ensuring no gaps or overlaps.

Students transition from descriptive comparison to measuring with a repeated unit, exploring why units are helpful.

Students apply indirect comparison strategies to solve real-world problems involving objects across the room.

Students compare the length of two objects that cannot be moved together by using a third object (a string or paper strip).

Students order three objects by length, identifying the longest and shortest in a set.
