INSTRUCTIONAL PROCEDURES

PERIOD 1 and 2: Measurement of mass

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1INTRODUCTION The pupils are asked to mention and demonstrate the ways in which they weigh the objects in their localities The class uses the sand of different quantity being poured into 2 bags   to brainstorm and formulate the meaning of mass- Mass is the amount of matter in an object.Weight describes how heavy or light an object is Pupils pay attention STEP 2EXPLANATION The teacher explains that there are two types of measurement for mass and weight and gives examples of each1. Olden methods e.g a grain of wheat or barleycorn used to weigh the precious metals silver and gold. Larger units preserved in stone standards were developed that were used as both units of mass and of monetary currency. 2. Standard methods- balance(triple beam or electronic), dial spring balance etc Pupils pay attention and participates STEP 3DEMONSTRATION She further explains and demonstrates the metric unit of mass and weight10 milligrammes = 1 decigramme10 decigrammes = 1 centigramme10 centigrammes = 1 gramme1000 grammes = 1 kilogramme1000 Kilogrammes= 1 tonne Pupils pay attention and participate STEP 4NOTE TAKING The teacher writes a short note on the board The pupils copy the note in their books

NOTE

Mass is the amount of matter in an object.

Weight describes how heavy or light an object is

There are two methods for measuring mass and weight

1. Olden methods e.g a grain of wheat or barleycorn used to weigh the precious metals silver and gold. Larger units preserved in stone standards were developed that were used as both units of mass and of monetary currency.

1. Standard methods- balance (triple beam or electronic), dial spring balance etc

Metric unit of mass and weight

10 milligrammes = 1 decigramme

10 decigrammes = 1 centigramme

10 centigrammes = 1 gramme

1000 grammes = 1 kilogramme

1000 Kilogrammes= 1 tonne

EVALUATION:    1. Define these terms

1. Mass b. Weight
2. Describe two olden methods and two standard methods of measuring mass and weight
3. Recite the metric unit of mass and weight

CLASS ACTIVITY: Pupils are placed in small groups, and asked to measure, compare and analyse their varying mass.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 3: Movement

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1INTRODUCTION The teacher revisits the previous lesson and introduces the new topic by explaining what movement means- Movement is the act of changing place and position Pupils pay attention STEP 2EXPLANATION The teacher enumerates the different movement patterns1. crawling2. walking3. bending4. kicking5. squatting6. galloping7. climbing8. jumping9. jogging Pupils pay attention and participates STEP 3DEMONSTRATION She further explains and demonstrates each of the movement patterns and asks the pupils to do the same Pupils pay attention and participate STEP 4NOTE TAKING The teacher writes a short note on the board The pupils copy the note in their books

NOTE

Movement is the act of changing place and position

movement patterns

1. crawling
2. walking
3. bending
4. kicking
5. squatting
6. galloping
7. climbing
8. jumping
9. jogging

EVALUATION:    1. What is movement?

1. Give five examples of movement

CLASS ACTIVITY: Pupils in pairs, demonstrate different movement patterns

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
