Measuring and Comparing Object Lengths
Grade 2 Mathematics Using the same unit to measure Finding differences between lengths
Essential Question
How can measuring with the same unit help us compare the lengths of objects?
Learning Target
I can measure two objects using the same unit and tell how much longer or shorter one is than the other.
Teacher Demonstration
Watch me measure a pencil and crayon I'll use the same ruler for both objects Line up the ruler starting at zero Count the inches carefully Write down both measurements
Let's Measure Together!
Work with your partner Measure the book: ___ inches Measure the notebook: ___ inches Which one is longer?
Finding the Difference
{"left":"Pencil = 6 inches\nCrayon = 4 inches\nSubtract to find the difference","right":"6 - 4 = 2 inches\nThe pencil is 2 inches longer!"}
Your Turn to Practice!
Choose two classroom objects Measure each one carefully Write down both measurements Calculate the difference Share your results with the class
