Problem of the Day
Objective: Today I will determine the difference in the length of two objects
using addition.
Vocabulary Difference in length: how much longer or how much shorter one object is than the other
Standard (Customary) Units of Measurement: inch = thumb-to-knuckle length foot = 12 inches yard = 3 feet (36 inches) Metric Units of Measurement: one centimeter = width of pinky 25 centimeters = one ruler one meter = four rulers (100 cm)
Teacher Resources Considerations: Now that students have experience in measuring objects, they will begin to compare the lengths of objects. This can be introduced with nonstandard units of measurement, such as paperclips before using rulers. Remind students there are two ways to compare objects. One object can be longer than another and one object can be shorter than another. The focus of this lesson should be on drawing a number line and adding on from the shorter length to the longer length.
Steps: 1. Measure two objects using the same unit. 2. Label a number line Start with the smallest measurement. Stop at the largest measurement. 3. Starting with the smallest measurement, count on to find the difference 4. Write a comparison sentence. Include units.
Application of MPs: MP5: What tool can you use to help you solve the problem? MP6: What do you need to do to ensure your answers are correct when measuring? MP7: What concepts or rules help you determine how to measure each length?
