Subject:  Math

Grade: 1

Lesson Objective: To order objects by length

Common Core StandardCCSS.MATH.CONTENT.1.MD.A.1- Order three objects by length; compare the lengths of two objects indirectly by using a third object.




  • Why would we need to know how long something is?  (Allow the students to answer.)



  • Some of the reasons that we would need to know the length of an object is to figure out if it would fit in a specific area or so that we could add something new to it.
  • For example, you need to know the length of your legs so that you can get new pants that fit. 
  • When measuring the length of an object, what object could you use?  (Allow the students to answer.)
  • You could use a ruler, yard stick or tape measure to measure the length of an object. 
  • Did you know that you could also use another object?  If you wanted to know how long your desk was, you could use your hand to measure it. 
  • Sometimes we need to know the length of two objects so that we can figure out which one is longer or shorter. 
  • You can do this by measuring with a ruler.  You can also do this by using another object to compare them.
  • For example, if I was going to compare the length of two of you, I could use the door as the third object.  I would have two of you go stand next to the door and then look to see who is longer.  (Demonstrate this).
  • You can do this same thing when you are comparing the length of objects on paper. 
  • Today, you are going to be comparing the lengths of different animal homes. 
  • You are going to be looking at different pictures of animal homes.  You will be using a book to compare the length of the objects to help you answer the questions.
  • After you compare the objects and answer the questions, we will go over your answers.
  • Does anyone have any questions?



  • Who would like to share your answers?  (Allow the students to share.)
