Problem 1

Step1: Recall 1 meter scale

1 meter = 100 centimeters; identify objects >100cm.

Step2: Evaluate each option

• Paper clip width: ~1cm <1m
• Math workbook length: ~25cm <1m
• Classroom width: ~5-10m >1m
• Classroom door height: ~2m >1m
• Finger length: ~10cm <1m

Step1: Convert kilometer to meters

1 kilometer = 1000 meters

Step2: Compare heights

Compare 828 meters to 1000 meters.

Step1: Convert kilometer to meters

1 kilometer = 1000 meters

Step2: Compare distances

Compare 9500 meters to 1000 meters.
