Content Development (NOTES FOR FIRST LESSON/PERIOD ONE)
Sub-Topic I: The instruments required for good board practice
The instruments required for good board practice are:
(1) Drawing board and Tee-square
(2) Set-square (30o, 60o , 45o angles)
(3) Compass and Dividers
(4) Protractor and French curves
(5) Drawing pencils (HB and 2H)
(6) Eraser and Drawing paper
Sub-Topic II: Setting Drawing Paper on the Board
Step 1: The drawing board is conveniently placed on the table with the paper on the board, leaving equal size all round, with the Tee-square edge to the left hand side.
Step 2: Place the tee-square on the paper and gently move or slide the tee-square to the top edge of the paper. Set the top edge of the paper parallel to the edge of the tee-square with the stock of the tee-square firmly against the edge of the drawing board on the left-hand side.
Step 3: Hold the paper with four pieces of adhesive tape or two metal cups to hold the paper in position at four corners.
Step 4: Gently slide the tee-square down without moving the paper.
Sub-Topic III: Sharpening of Drawing Pencils to conical point and knife edge
A well sharpened pencil is very essential to technical drawing. Pencils for lettering and freehand sketching should be sharpened to a ‘conical point’ while those for geometrical or engineering drawing should be sharpened to a ‘chisel point’.
All horizontal lines are drawn with the aid of tee-square. The set-square is used sitting squarely on the… Click here to order the complete second term Basic Technology Lesson Note for JSS1

TOPIC: Freehand Sketching
SUB-TOPICS: (i) Definition or meaning
(ii) Techniques of Sketching
Content Development (NOTES FOR FIRST LESSON/PERIOD ONE)
Sub-Topic I: Definition or meaning
Freehand sketching is one of the quickest methods by which the shape of an object can be communicated to others without using any drawing instrument except a pen or a pencil. Examples of free hand sketches are… Click here to order the complete Lesson Note on Basic Technology JSS1 second term
