Key Concepts

  • Centimeters as a unit of measurement
  • Using a ruler to measure length
  • Understanding the relationship between numbers and length

Learning Objectives

  • Students will be able to identify the centimeter side of a ruler.
  • Students will be able to measure objects using centimeters.
  • Students will be able to record the length of an object in centimeters.

Educator Instructions

  • Introduction (5 mins)
    Begin by watching the YouTube video 'Grade 1: Saxon Math Lesson #117 Measuring Line Segments Using Centimeters And Cute Kittens'. Pay attention to how the teacher introduces the concept of centimeters and how to use a ruler.
  • Ruler Exploration (5 mins)
    After watching the video, provide each student with a ruler. Ask them to identify the side with centimeters. Have them count the centimeters from 1 to 30.
  • Guided Measurement (10 mins)
    Following the video's example, guide students in measuring various classroom objects using the centimeter side of the ruler. Start with smaller objects like pencils or erasers. Emphasize starting at the '1' mark (or the edge) and reading the measurement at the other end.
  • Independent Practice (10 mins)
    Have students choose 3-5 objects around the classroom or their home to measure independently. They should record their measurements on a piece of paper. Encourage them to help each other.
  • Wrap-up and Sharing (5 mins)
    Gather the students together and have them share their measurements. Discuss any challenges they faced and reinforce the correct method for measuring in centimeters.

Interactive Exercises

  • Centimeter Scavenger Hunt
    Hide objects around the classroom/home and give students clues to find them. The clues should include a measurement in centimeters (e.g., 'Find something that is 15 centimeters long').
  • Measurement Challenge
    Provide students with different objects and ask them to estimate their length in centimeters before measuring. Then, have them measure the objects to see how close their estimates were.

Educational Standards

CCSS.Math.Content.1.MD.A.2:Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps. CCSS.Math.Content.1.NBT.A.1:Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
