This hard worksheet pushes second graders into unit conversion and length reasoning. Multiple-choice problems convert a 6-foot jump rope to inches, change a 48-inch table into feet, and subtract 15 cm from a 40 cm string. Students also pick the object closest to 1 meter from choices like a paperclip, baseball bat, school bus, and pencil. Fill-in items cement that a meter stick has 100 centimeters, three feet equals 36 inches, and a ladybug is about 1 centimeter long. A challenging mix that strengthens flexible thinking between customary and metric units.
