Students often have a hard time distinguishing between inches and centimeters, especially when comparing the two measurements. This Measurement unit has 6 lessons/activities where students measure objects in centimeters and inches, find the differences in their measurements, and comparing measuring in centimeters and inches by answering why you get two different measurements when you measure in inches and centimeters.
Here are the activities listed below. There are two sets of activities with and without a blue striped background.
1. Measure It!- In this activity, students are given a crayon, pencil, paper clip, and glue stick and other objects around the room. Students measure each object in inches and/or centimeters, and complete three tasks measuring and writing about why you get two different measurements when you measure in centimeters and inches.
2. Body Measurements: In this two task activity, students measure the lengths of body parts to compare inches to centimeters and then compare their body measurements to other student’s measurements.
3. Find A Measurement: In this set of activities, students go around the room finding measurements that are an allotted amount longer or shorter than an object.
4. Greatest Pencil Challenge: In this activity, students are placed into small groups where they compare the lengths of their pencils in small groups to determine whose pencil is the longest by comparing pencil measurements. Next, the students with the longest pencil from each small group will compare their pencils to see who has the longest pencil. The class completes a bar graph, pictograph, or line plot using all the lengths of the pencils used in the great pencil challenge.
5. Cotton Ball Slingshot: In this activity, students work with partners to compare measurements in the cotton slingshot challenge. Each partner uses a spoon to flip one cotton ball each, and partners compare the length of their slingshot challenge measurements.
6. Who’s Right: In this activity, students measure the object in inches and centimeters. Then students read the word problem and determine whether one character, both characters, or neither character is correct in measuring each object in either centimeters or inches.
