CONTENT OF THE LESSON  

INTRODUCTORY ACTIVITIES 

Teacher’s/Pupil’s Review on Pascal’s Calculator

 

EARLY MECHANICAL CALCULATING DEVICE – Analytical Engine 

Teacher’s/Pupil’s Activities – Displays Analytical Engine  (if available) or a chart showing Analytical Engine for the pupils to observe and describe.

 

 

ANALYTICAL ENGINE 

Analytical Engine is a general – purpose computer that can perform basic calculations such as arithmetic logic unit and basic programmatic flow control because of its integrated memory.

 

PRACTICAL DEMONSTRATION USING ANALYTICAL ENGINE FOR BASIC ARITHMETIC SUCH ADDITION AND SUBTRACTION 

Teacher’s/Pupil’s Activities – if the device is available, call for expert if you are unable to operate the device or watch YouTube video how to use the device.

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Shows pictures of Analytical Engine  computing device to the class.

Pupil’s Activities – Bring pictures/cut outs of Analytical Engine  computing devices.

 

 

3. Demonstrates the use of Analytical Engine .

Pupil’s Activities – Use the Analytical Engine to solve different arithmetic problems.

 

CONCLUSION

  • To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

 

LESSON EVALUATION 

Pupils to:

1. identify Analytical Engine among all early mechanical calculating devices

2. describe Analytical Engine counting device.

3. operate Analytical Engine counting device.
