This medium worksheet sends second graders into real-world length thinking. Fill-in problems estimate that a kitchen counter is about 3 feet high, a stamp is about 2 centimeters wide, a TV remote is about 8 inches long, and a toothbrush is about 18 centimeters. Students also break a 30-inch skateboard into 2 feet and 6 inches, add Mia's 15 cm and 20 cm ribbons, and convert a 50-foot garden hose to 600 inches. A matching round links a grape, umbrella, bed, and button to estimates from 1 cm to 6 feet. A focused mix that grows estimation confidence.
