About this worksheet

An estimate is a sensible guess made without measuring, and it only works when a child knows what the units feel like. An inch is about the width of a thumb, a foot is about the length of a ruler, a centimeter is about the width of a fingernail and a meter is about as long as a big step. This worksheet gives ten objects from a child's day, a pencil, a door, a school bus, and three numbers with units to choose from.

The wrong choices are far too big or far too small, such as a pencil that is 7 feet long, so the child has to picture the object. Each sheet uses one system, inches and feet or centimeters and meters. Ask your child to hold up their hands to show how big the object is.

What your child will learn

Choose a sensible estimate for a length
Picture the size of a unit
Tell inches from feet and centimeters from meters

Common Core standard: 2.MD.A.3

Worked example

A pencil is about 7 inches long. It is not 7 feet (that is taller than a door) and not 70 inches.

Common mistake

Choosing the right number with the wrong unit, such as a book that is 25 meters long.

Helpful hint

Picture the object, then picture the unit next to it.

Next skill: Compare Length Differences Earlier: Ten and Hundred More or Less
