26. discussion
Unit of measure
centimeter (cm) and Meter (M)

27. discussion
Centimeter is used to
measure small and shorter
objects, example notebooks,
pencils, and crayons ,etc

28. discussion
Meter is used to measure big
or wide and much longer
objects, example a window,
door, and tables ,etc

29. generalization
How do we measure the
length of an object?

30. generalization
Measuring length means measurement of
the length of any object with the help of
measuring tools like a ruler, measuring
tape, or a meter stick. For example, the
length of a pencil can be measured in cm
using a ruler and the length of a door using
a meter stick

31. application
Work in Pairs. The teacher will prepare five objects
with different lengths. Measure these objects with given
measuring devices (tape measure, meter stick or ruler)
at five station.
Station 1 – a piece of wood = ____m
Station 2 – a shoe lace = _____m
Station 3 – a height of a module = _cm
Station 4 – a comb = __cm
Station 5 – a pencil = __cm
