A Math lesson on Measurement
3, 2, 1
ME AND MY
Grade Level: 1 – 3
Materials chalk, measuring tape, pencil and paper
Description of Activity: On a nice sunny day, take the students outside and have them get in partners. Repeat this activity three times during the day, in the morning, around noon, and in the afternoon. Have one partner stand still while the other partner marks with chalk the beginning and end of the shadow. Measure the length of the shadow. Repeat with the other partner.
Extensions: You could include subtraction, by having the students figure the difference in the lengths between the shadows. Science could also be incorporated by discussing why the shadow changes lengths.
