Lesson DevelopmentStep 1(10 minutes)9.25 am – 9.35 am

Measuring from the example. Pupils will be watching a video about the correct way to take measurement of length.

Pupils will listen to the teacher explanation about the correct way to take a measurement like the video explained earlier by using giant ruler.

Pupils will be asked to take out their exercise book or any measurable object and a ruler then measure it just like the video does.

Pupils who did not record the correct measurement will be guided by teacher.

Teacher : Could you read the measurement above?

- Yes. Can you tell me what the reading is?

-24cm

Teaching ResourcesRuler, Laptop and LCD, giant ruler, file

Thinking skill- Understanding

Moral values- Build up confidence-honest during measuring

Lesson DevelopmentStep 2(10 minutes)9.35 am – 9.45 am

Let’s practice!

Activities of student centered

Classify between measurable and non-measurable object.

Pupils will be given few objects. Pupils must classify between measurable and

non-measurable object. Pupils must show which object that can be

measured.Student measure the measurable length objects. The objects given:

Teaching ResourcesScissors, skewers, staplers, erasers, color pens, bottles of water, sand and containers

stapler eraser

skewers scissor

colour pen bottle of water

sand

Teacher:- Why the objects can be measured and cannot be measured?- I want you to measure the length of the measurable length objects.

Thinking skill- Recognize- Classify- Understanding

Moral values- Diligence- Awareness - Carefulness

Lesson DevelopmentStep 3(10 minutes)9.45 am – 9.55 am

Comparing length of two objects Pupils will measure two different things in different length and records the readings.

Pupils will compare the length and tell which one is longer.

Pupils will see the slide show of two different lengths of trees.

Pupils will determine which one is longer.

Teacher : Could you read the measurement? Can you tell me what the reading is? Compare the readings and tell me which one

is longer.

Teaching Resource- power point presentation-giant ruler
