Measuring and Marking Out Tools
20 Grade 7 Pre-Technical Studies questions on Measuring and Marking Out Tools, with worked marking schemes. 20 questions are available on this topic in full.
Question 1
4 marksBefore cutting a piece of timber, James must first measure and mark out the dimensions accurately on the workpiece.
(a) Name two measuring or marking out tools James can use. (2 marks)
(b) Explain why accurate measuring and marking out is important before cutting a material. (2 marks)
(4 marks)
Marking scheme
(a) Any two tools (1 mark each): steel rule / tape measure (measuring), try square (marking square lines / testing squareness), marking gauge, scriber, marking knife, divider, pencil. (b) Accurate measuring and marking out is important because it ensures the workpiece is cut to the correct size and shape, which prevents wastage of material, saves time, and ensures the parts fit together properly in the final product. (2 marks)
Question 2
1 markA learner needs to measure the length of a curved garden hose accurately. Which measuring tool is MOST suitable?
A. A flexible tape measure, because it bends along curves
B. A rigid steel rule, because it cannot bend
C. A try square, because it makes right angles
D. A divider, because it spaces points

4 marksDistinguish between a measuring tool and a marking out tool, giving one example of each.
(4 marks)
Marking scheme
2 marks: A measuring tool is used to determine sizes/dimensions such as length or thickness (e.g. steel rule, tape, vernier caliper); 2 marks: A marking out tool is used to make lines, points or shapes on the workpiece to guide cutting/working (e.g. scriber, marking gauge, centre punch, divider). Must give one correct example for each.
Question 4

A. A try square
B. A steel rule (ruler)
C. A scriber
D. A mallet

5 marks(a) Name the tool used together with a try square when marking a line square to an edge on timber.
(b) Describe how you would use a try square to mark a line square across a piece of wood.
(5 marks)
Marking scheme
(a) 1 mark: a marking knife/pencil (or scriber). (b) 4 marks: place the stock (handle) of the try square firmly against the true/finished edge of the wood (1); ensure the blade lies flat across the face (1); hold firmly so it does not move (1); mark/scribe along the blade with a pencil or marking knife to produce a line square to the edge (1).
Question 11
1 markA steel rule is preferred over a plastic ruler in the workshop MAINLY because it is
A. cheaper to buy
B. brightly coloured
C. more durable and accurate
D. lighter to carry

5 marksA learner obtained different readings each time he measured the same metal bar with a steel rule. State two possible causes of the errors and one way to improve accuracy.
(5 marks)
Marking scheme
2 causes x 2 marks: reading from an angle (parallax error); not aligning the zero/end of the rule with the edge; worn/damaged rule end; misreading the graduations. 1 mark solution: read the rule straight on/at eye level (avoid parallax); use a rule with a clear undamaged edge; use a more precise tool e.g. vernier caliper. Accept 2 causes + 1 improvement.
Question 17
1 markA learner wants to mark a straight line on a wooden board before cutting it. Which tool is correctly used together with a pencil for this task?
A. A try square, to mark lines at right angles to an edge
B. A hammer, to press the line into the wood
C. A pair of pliers, to grip the wood while marking
D. A screwdriver, to draw the line

6 marksA learner has been asked to mark out a straight line and a right angle on a piece of wood before cutting.
(a) Name the tool used to mark a line that is at a right angle (90 degrees) to the edge of the wood. (2 marks)
(b) State two reasons why accurate measuring and marking out is important before cutting any material. (4 marks)
(6 marks)
Marking scheme
(a) A try square. (2 marks) (b) Reasons (any two): (i) It ensures the parts fit together correctly and the joint is accurate. (ii) It avoids wastage of material that would result from cutting in the wrong place. (Other valid points: it saves time because work is done correctly the first time; it produces a neat, good-quality finished product; it ensures the dimensions match the working drawing.) (4 marks)
Question 20
