Measure with Ruler (metric) - Half Centimeters from Middle

This math topic focuses on measuring with a ruler using metric units, specifically centimeters and half centimeters. The problem set involves measuring the lengths of pencils using a centimeter ruler and identifying measurements from a list of multiple choices. These problems are designed to help learners understand how to start measurements from half centimeter segments and increase accuracy in reading and interpreting metric measurements in real-world contexts.
