Explain what a meter is. Take a step and explain that this is approximately a meter. Meter is abbreviated as m. Show the blackboard ruler and explain that this is also a meter. Have the students find objects in the classroom that are approximately a meter long. Then you show several images on the interactive whiteboard. Ask which objects are approximately one meter, and circle them. Remind the students that a large step is approximately one meter. Then you show an image and the students determine if the object is larger, smaller, or approximately one meter.

To check if the students understand what a meter is, you can ask the following questions:

- What abbreviation is used for a meter?

- What is approximately one meter long?
