Measure Lengths (Grade 2)

Videos, examples, lessons, and solutions to help Grade 2 students learn to measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
Estimate lengths using units of inches, feet, centimeters, and meters.
Common Core: 2.MD.1 and 2.MD.3

Suggested Learning Target

• I can select an appropriate tool (e.g., ruler, yardstick, meter stick, measuring tape) to measure an object.
  
• I can measure the length of an object using a tool.
  
• I can measure to the nearest inch, centimeter, yard, or meter
  
• I can explain why we use standard units of measurement instead of non- standard units
  
• I can estimate before measuring to help determine the appropriate measurement tool and unit
  
• I know the connection between a ruler and a number line
  
• I can measure real-world objects
  
• I can estimate the length of a given object in inches and feet.
  
• I can estimate the length of a given object in centimeters and meters.
  

The following diagrams show how to use a ruler correctly to measure a pencil. Scroll down the page for more examples.

 

How to Use a Ruler Correctly:

1. Start at Zero:
   Always align one end of the object with the “0” mark on the ruler. Some rulers have a small space before the zero; always use the actual zero point and not just the edge of the ruler.
   
2. Keep it Straight:
   The measuring tool must be held straight along the length of the object, not curved or angled.
   
3. Read the Markings:
   a) Whole Numbers: Practice identifying the whole numbers (1, 2, 3…) for inches or centimeters.
   b) Half and Quarter Marks: For Grade 2, some curricula introduce measuring to the nearest half-inch or half-centimeter. Point out the longer line in the middle of each whole number.
   c) Reading the Endpoint:
   Read the number on the ruler where the other end of the object lines up.
   

Measuring to the Nearest Inch and Half Inch
Inches are a customary unit of length. This video will teach 2nd grade students how to use a ruler to measure to the nearest inch and half inch.
