How Big is a Foot?

In this lesson, children will use butcher paper to trace their bodies and predict their height and width with their feet.

Content Area:

Curiosity and Wonder

Learning Goals:

This lesson will help toddlers and preschoolers meet the following educational standards:

  • Develop beginning skills in the use of science and engineering practices, such as observing, asking questions, solving problems, and drawing conclusions
  • Understand that living things grow and change.

Learning Targets:

After this lesson, toddlers and preschoolers should be more proficient at:

  • Showing an awareness of changes that occur in oneself and the environment
  • Planning and carrying out simple investigations
  • Using mathematical and computational thinking
  • Making meaning from experience and information by describing, talking and thinking about what happened during an investigation

Lesson plan for toddlers/preschoolers

Step 1: Gather materials.

Note: Small parts pose a choking hazard and are not appropriate for children age five or under. Be sure to choose lesson materials that meet safety requirements.

Step 2: Introduce activity.

  1. Ask the children to look at their feet. Explain that they will be using their feet to measure their height and width.
  2. Explain to the children that you are going to read a book about measurementExplain that the book is about a king who thinks of a lovely present to give to his wife, the queen. But there is a problem with the present. Explain to the children that they will need to figure out what the problem is and predict what will happen with the king and his gift to the queen.
  3. Read the book, How Big Is A Foot? Stop at the page where this question is asked: “Why was the bed too small for the queen?”
  4. Finish the story and discuss how the problem was solved.

Step 3: Engage children in lesson activities.

  1. Explain that the children are going to use their own feet to measure their width and height and decide on a measurement for their own beds.
  2. Using the butcher paper, have the children trace each other’s bodies onto the paper. Then cut a rectangle (the bed) around the body outline. The children can then decorate their body tracings and beds.
  3. First, ask the children to use their own feet to measure the width of their body tracings. Then ask them to measure the height of their body tracings. Write down their findings on a piece of paper.
  4. After the activity, discuss what occurred. Ask: “Would we get the same findings if we used other children’s feet to measure? Would we get the same findings if we used the size of your foot when you were a baby?”

Additional Extensions

  • Give the children rulers and let them use rulers to measure the width and length of their bodies.
  • Have the children predict how many feet wide they are and how many feet long they are.

Step 4: Vocabulary.

  • Predict— To guess what might happen next
  • Investigate—To seek out information by observing, experimenting or testing
  • Findings—New information that is gained after an investigation
  • Conclude—To make statements about what was learned after an observation or experiment

Step 5: Adapt lesson for toddlers or preschoolers.

Adapt Lesson for Toddlers
Toddlers may:
  • Have difficulty measuring with their own feet
  • Have difficulty grasping the idea of measuring a bed for their body tracings to lie on
Child care providers may:
  • Trace and cut out multiple copies of the children’s feet so that they can line them up, one in front of the other, and keep better track of how many feet it takes to measure the width and length of the bed needed
  • Have the children measure themselves. “I am ________ feet high and ________ feet wide.”
Adapt Lesson for Preschoolers
Preschoolers may:
  • Be able to easily use their feet to measure the length and the width of the bed
  • Easily calculate and measure the length and the width of the bed
Child care providers may:
  • Give the children rulers and let them use the rulers to measure the width and length of their bodies
  • Have the children predict how many feet wide they are and how many feet long they are

Music and Movement

Outdoor Connections

Tell the children to measure the perimeter of an outdoor area using their feet. You can also use chalk to draw rectangles and squares on the pavement and ask the children to measure these shapes or measure the squares on the sidewalk.
