Teacher's field guide

What Students Need to Do: Students choose a metric ruler, meter stick, balance, graduated cylinder, or thermometer to match what they need to measure. They read the scale carefully and record a number with the correct metric unit.
What Mastery Looks Like: Students select the right tool and unit without prompting. Their measurements are reasonable, include units, and are accurate to the smallest marked interval on the tool.
Common Misconceptions: Students may mix up centimeters and meters, or milliliters and liters. They may measure from the ruler’s edge instead of zero or read the top of a liquid’s curve. Some record a number without a unit.
How to Assess It: Exit ticket: Measure a pencil in centimeters, then name the best tool and unit for measuring 200 mL of water. Require numbers, units, and tool names.
