PERIOD 2 and 3: CPU. Physical fitness
PRESENTATION | TEACHER’S ACTIVITY | PUPIL’S ACTIVITY |
STEP 1 INTRODUCTION | The teacher revisits the previous lesson and introduces the new topic by explaining what CPU is-
CPU means Central Processing Unit. The CPU, also known as the Processor is the part of the system unit that controls all the activities of the computer. | Pupils pay attention |
STEP 2 EXPLANATION | The teacher using the chart, enumerates the different the three main parts of the CPU 1. ALU: Arithmetic and Logic Unit is the part of the CPU that carries out all mathematical, logical and decision operations 2. CU: Control Unit is the part of the CPU that sends data to the ALU and Memory Unit. It directs all the operations in the CPU 3. Memory Unit: It is also known as the RAM (Random Access Memory). It stores all the data, instructions and intermediate results | Pupils pay attention and participates |
STEP 3 DEMONSTRATION | She displays the main parts for the pupils to identify and describe their functions | Pupils pay attention and participate |
STEP 4 NOTE TAKING | The teacher writes a short note on the board | The pupils copy the note in their books |
NOTE
