## Reflection: Developing a Conceptual Understanding Comparing Lengths - Section 3: Practice

When we created number lines in previous activities, students were able to successfully identify points on the number line, which helped them better understand measurement. I noticed in a previous lesson with measurement that my students were struggling to use the ruler and measure objects to the nearest inch, half inch and quarter inch because of the added lines on the rulers. I felt that it was necessary to give them additional time to practice and build fluency in measurement by exposing them to measuring different objects and comparing their lengths. Students were able to find similar objects, or very different objects, based on their comfort level and I was able to be more involved with struggling students by pulling them for 1-on-1 instruction.
