Length Measurement

Objectives:
- To learn how to measure length and height in inches and feet.
- To measure objects in inches, feet, and yard.
- To find and measure objects that are about 1 inch, 1 foot and I yard.
- To investigate inches, feet, and yard; to know the conversion of one foot in inches and one yard in feet.

Materials: a ruler, yard stick, a pencil, papers, a blackboard, notebooks

Procedure:

Have the children bring out their rulers, and let them find out how many inches are there in their ruler.

Draw one foot line on the blackboard and ask a student volunteer to measure the line using his/her ruler and find out how many rulers it takes to measure it. Students will find out that it takes one ruler to measure the line drawn. Point out that the line is one foot and it takes one ruler to measure it, the equivalent of 12 inches.

Show a yard stick to the class. Ask a student volunteer to measure it using his/her ruler and find out how many rulers it needs to measure it. Students will find out that a yardstick is equivalent to 3 rulers.

Write the following conversions on the blackboard for students to copy in their notebook later on.

Point out that the height of a person is measured in feet.

Let the children go around the classroom to measure objects that are about 1 inch, 1 foot, and 1 yard; find a partner that they can take turn in measuring their height.


Evaluation:

1. Application on the conversions (transmutation) learned.
Examples: 2 feet = _______ inches 24 inches = _________ feet
2 yard = _______ feet 6 feet = ___________yards

2. List objects on the blackboard, and ask which unit of length measurement should they use to measure them.
Examples: pencil = ____ school yard = _____
blackboard = ___ length of the room =
math book = ____ teacher’s table = _____
paper clip = _____ student’s desk = _____

3. Measure ten objects in the classroom.

Enrichment:

Draw a miniature house, a school, a playground according to the specific measurements given by the teacher.

As fast as the students can, think of ten things of different length and arrange them from shortest to tallest. Note them down in their notebook.

Great plan! Hands-on work is so important in learning. :-)
