Learning Objective
I can measure to the nearest inch or centimeter.
Today we will learn how to measure to the nearest inch or centimeter. Math helps us solve problems and understand the world around us.
Measurement assigns a number to a physical attribute (length, weight/mass, time, capacity, temperature). Non-standard units (paper clips, hand spans) introduce the concept; standard units ensure everyone gets the same result. Length in U.S. customary: inches, feet (12 inches), yards (3 feet), miles. Length in metric: millimeters, centimeters (10 mm), meters (100 cm), kilometers (1000 m). Weight/mass: pounds and ounces (U.S.); grams and kilograms (metric; 1 kg = 1000 g). Always measure to the nearest marked unit, record the number AND the unit, and choose appropriate units (you measure a classroom in feet, not miles).
Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!
Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.

Teaching Tip
For younger learners: Use concrete objects and hands-on activities when teaching measure to the nearest inch or centimeter. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
