About the Measurement Worksheets

Measuring length has two parts that children often learn separately: knowing what an inch or a centimeter is, and knowing how to read the marks on a ruler. These sheets start before the ruler, with blocks laid end to end, because counting units is the idea a ruler is built on.

The How to Read a Ruler sheet shows two inches enlarged, with the half and quarter marks labeled, and the rule that causes the most mistakes: start at the 0 mark, which on many rulers is not the very end. The four measuring sheets then go from whole inches to half inches, quarter inches and centimeters.

Every ruler on these pages is drawn at its real size, and each object is drawn to exactly the length in the answer key. A child reads the length straight off the printed ruler, so the answers are right even if your printer shrinks the page a little. Printed at 100%, the rulers match a real one.

Estimating Length gives each unit an everyday size to hold in mind: an inch is about as wide as a quarter, a foot about as long as a sheet of paper, a centimeter about as wide as a little finger, and a meter about as wide as a door. Estimate, Then Measure puts that to work on five things drawn at real size. Length Story Problems and Length on a Number Line are the 2nd grade word problems that add and subtract lengths within 100.

Longer and Shorter measures two things and asks for the difference. Two more sheets cover liquid measures: a chart of how gallons, quarts, pints and cups fit inside one another, and a page of conversions. For a paper ruler to cut out, see the printable rulers. For telling time and money, see the telling time and money worksheets.

Frequently Asked Questions

How do you read a ruler?
Put the 0 mark at one end of the thing you are measuring and read the mark at the other end. On an inch ruler the longest marks with numbers are whole inches, the mark halfway between two numbers is a half inch, and the shorter marks on each side of it are quarter inches.
What grade learns to measure with a ruler?
Children measure with non-standard units such as blocks in kindergarten and 1st grade. Whole inches and centimeters are taught in 2nd grade, half and quarter inches in 3rd grade, and converting between units in 4th grade.
What is the difference between inches and centimeters?
Both measure length. An inch is the bigger unit: one inch is 2.54 centimeters, or about two and a half. Inches are part of the customary system used in the United States, and centimeters are part of the metric system.
How many cups are in a gallon?
There are 16 cups in a gallon. A gallon is 4 quarts, each quart is 2 pints, and each pint is 2 cups, so 4 × 2 × 2 = 16.
How many cups are in a quart and in a pint?
A quart is 4 cups and a pint is 2 cups. A quart is also 2 pints.
Do these worksheets need to print at exact size?
No. Each object sits on a printed ruler, so the answer is the same at any print size. If you print at 100% (not "fit to page"), the rulers will also match a real ruler.
