Lesson Planning of Conversion of Units of Length (Meters into Centimetres)
Subject Mathematics
Grade 4^{th}
Students` Learning Outcomes
 Convert meters into centimetres and vice versa.
Information for Teachers
 A centimeter is a unit of length which is denoted as cm.
 Cent means 100 therefore, 1 m = 100 cm.
 Multiply the meters with 100 to convert them in centimetres, so, cm = m x 100.
 Divide the centimetres with 100 to get meters, so, as; m = cm ÷ 100
 Centimeter is used to measure small lengths.
 A centimeter is approximately the width of the fingernail of an adult person.
 Centipede is called by this name because it has 100 legs.
 During this lesson the teacher should consult with textbook at each level where required.
Material / Resources
Writing board, chalk/marker, duster, measuring tape, scale, textbook
Introduction
 Write ‘meter and centimeter’ on the board and ask the students to share, whatever they know about these units.
 Ask the students have you seen your scale, there are two measuring units on it i.e. inches and centimetres.
 Tell them that today we will learn how to convert meters into centimetres and centimetres into meters.
Development
Activity 1

Activity 2 Conversion from centimetres to meters.

Activity 3

Sum up / Conclusion
 1 m = 100 cm
 Multiply the meters with 100 to convert into centimetres, as; cm = m x 100
 To convert centimetres into meters we divide the centimetres with 100, as; m = cm ÷ 100.
 To convert the meters into centimetres in the decimal numbers move the decimal point to two places on the right.
 To convert the meters into centimetres in the decimal numbers move the decimal point to two places on the left.
Assessment
 Complete the following table.
 Give some questions to solve from the text book.
