Today, I will measure lengths of objects using whole length units.
Vocabulary Whole length unit: any repeated unit that is smaller than the object being measured.
Teacher Resources Considerations: Students can cut out the strip of cubes provided in the student journal to complete this lesson. Or, the teacher may prefer to copy the strips of cubes on the next page, and distribute to students for this lesson.
Steps: The bandage is about 8 cubes long. The cubes are examples of whole length units because they are smaller than the bandage and are used to measure the length of the bandage.
1. Measure an object with whole length units (no gaps or overlaps). 2. Count how many whole length units long the object is. Application of MPs: MP5 : What tool will be used? Why? MP6: How can you use math vocabulary in
