About these worksheets
These worksheets introduce basic measurement concepts for early learners. Students compare the lengths of objects to determine which is longest or shortest and use non-standard units to measure objects by lining up equal-sized units end to end. Aligned with first grade measurement standards.
1md1
Compare three objects and decide which one is longest and which one is shortest. Put three objects in order from shortest to longest by looking at their lengths. Use words like longer, shorter, and same length to describe how objects compare. Pay attention to where each object starts and ends so the comparison is fair.
1md2
Measure the length of an object by lining up equal-size units end to end with no gaps or overlaps. Count the units to tell how long each object is. Use the same unit each time so measurements can be compared fairly.
4md1
Decide which of two lengths is longer or shorter when the units differ. Convert to a common unit before comparing. Recognize that the larger number is not always the longer length.
4md1
Decide which of two lengths is longer or shorter when the units differ. Convert to a common unit before comparing. Recognize that the larger number is not always the longer length.
2md1
Choose whether a centimeter ruler, a meter stick or a measuring tape best fits an object. Judge roughly how long an object is before deciding how to measure it. Explain why a tool can be too short, or longer than it needs to be, for a given object.
2md1
Decide whether an object is best measured in centimeters or in meters. Connect a unit to a real object of about that size. Recognize that centimeters suit small objects and meters suit large ones.
2md1
Measure the length of an object with a centimeter ruler. Line the end of an object up with zero before reading the other end. Read a length to the nearest whole centimeter.
2md1
Choose whether an inch ruler, a yardstick or a measuring tape best fits an object. Judge roughly how long an object is before deciding how to measure it. Explain why a tool can be too short, or longer than it needs to be, for a given object.
2md1 2md3
Decide whether an object is best measured in inches, feet or yards. Connect a unit to a real object of about that size. Recognize that yards are used for fields and long distances, feet for rooms and furniture, and inches for small objects.
2md1
Measure the length of an object with an inch ruler. Line the end of an object up with zero before reading the other end. Read a length to the nearest half inch, including marks that fall between two numbers.
2md1
Measure the length of an object to the nearest quarter inch. Read a mark that is neither a whole number nor the halfway point. Find the quarter inch marks among the eighths on a ruler.
2md1
Choose a ruler that measures in the unit the question asks for. Recognize that a centimeter ruler cannot give an answer in inches. Rule out a tool that is the wrong length as well as one in the wrong unit.

Measure an object that does not start at zero. Find a length by subtracting two ruler readings. Read a ruler to the nearest centimeter.
About these worksheets
Students practice measuring lengths using American customary units. Worksheets include reading rulers in inches, estimating distances, choosing appropriate units, converting between inches, feet, yards, and miles, adding and subtracting measurements in feet and inches, and working with mixed unit conversions. Resources span second through fifth grade standards.
2md1
Read a metric ruler to find how long a bar is in centimeters. Write the length using the correct decimal location.
3md4
Measure the length of an object using a ruler and standard units. Write down measurements clearly so they can be compared. Make a line plot to show a set of measurements.
4md1
Get better at making a reasonable guess for how long an object is without measuring it. Choose the best length from a few options by comparing what you see to familiar sizes (like an inch, foot, or yard). Decide which unit makes sense for an object’s length (inches, feet, or yards). Use benchmark lengths to tell when an estimate is too short or too long.
4md1
Choose whether inches, feet, yards, or miles makes the most sense for a given distance. Use what you know about common objects and places to make a reasonable estimate of a length. Explain why one unit is more appropriate than another for measuring a specific distance.
5md1
Convert between inches, feet, yards, and miles using the right conversion facts. Multiply or divide by conversion factors to change a measurement to a different unit.
4md2
Add lengths written in feet and inches. Subtract one feet-and-inches measurement from another. Regroup between inches and feet when the inches add past 12 or when you need to borrow a foot.
4md1
Convert a measurement written in mixed units (like feet and inches) into just the smaller unit. Use the correct conversion facts between inches, feet, yards, and miles.
3md4
Measure the length of a bar using a ruler marked in quarter inches. Read and write measurements that include 1/4-inch parts (like 2 3/4 inches). Make a line plot and mark how many times each length shows up.
4md1
Choose the customary unit that best fits what is being measured. Tell length, weight and liquid volume apart from the situation alone. Use the largest unit that still gives a number of at least 1.
5md1
Convert between inches, feet and yards. Choose whether to multiply or divide. Use the right conversion factor.
5md1
Convert between millimeters, centimeters and meters. Decide how many places to move. Choose whether to multiply or divide.
5md1
Use a conversion fact given in the problem. Decide whether to multiply or divide by it. Keep the whole problem inside one measurement system.
2md3

4md1
Choose the metric unit that best fits what is being measured. Tell length, mass and liquid volume apart from the situation alone. Use the largest unit that still gives a number of at least 1.
About these worksheets
