Lesson Plan: Snowflakes  Math (Gr K)

snowflakes math lesson

Subject:  Math

Grade: K

Lesson Objective: To compare the height of two objects

Common Core Standard:  CCSS.MATH.CONTENT.K.MD.A.2- Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference.

Materials:

Starter:

Say:

  • Have you ever compared how tall two objects were?  (Allow the students to answer.)

Main:

Say:

  • There are many times when we compare the height of objects.  You might stand next to a friend or family member to see who is taller, you might compare the height of two flowers or you might compare the height of two buildings.
  • When we compare the height of two objects, we are looking at them to see which object is taller and which object is shorter. 
  • You should always make sure that the objects that you are comparing are even.  That means that if you are standing next to a friend to see who is taller, you should be standing next to each other on level ground.  One of you should not be standing on a hill or a book because that will make you look taller.
  • Let’s compare the height of two objects in our classroom.  We will compare the height of a chair with the height of a bookshelf. 
  • I am going to put the chair next to the bookshelf.  Let’s look at the ground.  Are the objects next to each other on level ground?  It looks like they are.
  • When we compare the height of two objects, what should we look at?  (Allow the students to answer.)  We should look at the top of the objects.
  • Let’s look at the top of the chair and the top of the bookshelf.  Which object looks like it’s taller?  (Allow the students to answer.)
  • The taller object is the one with the top that is higher than the other object.
  • Today, you are going to be comparing the height of two objects.  You will look at the pictures of the objects and then figure out which one is taller or shorter.  You will circle the object that you think answers the questions, “which is taller” or “which is shorter.”
  • Does anyone have any questions?

Feedback:

Say:

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