Summary of strengths and areas for development from previous lesson:


Strengths: Students demonstrated a good understanding of basic drawing equipment (T-square, drawing board, pencils) and were
able to produce neat, straight horizontal and vertical lines. They engaged well with the initial practical tasks.
Areas for Development: Some students struggled with maintaining consistent line weight and keeping their drawing sheets clean.
There is a need to reinforce the importance of precision and proper tool handling. This lesson will build on their line-drawing skills by
introducing angles, which requires greater precision.
Learning Outcomes:
1.9
represent 3D information using 2D conventions
2.3
derive 3D solutions using appropriate media
2.8
construct a 3D representation of an artefact or abstract idea using a variety of media and methods
Key skills: MI&T, WWO, C, BL, BN, MM
Well-being indicators: AW, RT
Learning intentions
Cognitive
Identify the two main types of set
squares (45° and 30°/60°) and their
properties.
Use set squares individually to
accurately draw lines at 30°, 45°, 60°,
and 90°.
Combine set squares to construct 15°
and 75° angles.
Indicate connection to KS and Well-being
after each LI.
Affective: Apply these skills to
complete a practical drawing exercise
with precision.
Success Criteria
Cognitive
Name the two types of set squares
and state the angles on each.
Demonstrate how to draw a 30°, 45°,
and 60° line using the correct set
square and a T-square.
Show the teacher how to position the
two set squares together to create a
15° angle and a 75° angle.

Complete the Microsoft logo drawing
exercise, ensuring all lines are
straight, parallel, and perpendicular
as required.

Time Teaching and Learning
Introduction
Teacher greets the class and briefly recaps the previous lesson on basic line work with Tsquares.
"Last time, we mastered horizontal and vertical lines. Today, we're adding angles to our toolkit
using these essential instruments: set squares."
Introduce Learning Intentions (3 mins):
Display the Learning Intentions and Success Criteria on the board.
Explain clearly what students will be able to do by the end of the lesson (draw specific angles,
combine set squares, and complete a practical task).
Introduce Set Squares (5 mins):
Teacher Demonstration: Basic Angles (10 mins)
Teacher demonstrates on the whiteboard/projector how to draw lines at 45°, 60°, and 30° using
the T-square as a fixed base.
Drawing a 45° Line: "Place the 45° set square on the T-square. Slide it to the desired position
and draw along the hypotenuse." (Show Orientation 1 & 2 from the slides).
Drawing 60° and 30° Lines: "Now, with the 30°/60° set square, we can draw two different
angles. Align the base and draw along the hypotenuse for a 60° line. Flip it to use the other edge
for a 30° line."
Emphasize keeping the set square firmly against the T-square for parallel lines.
Assessment
Assessment: Questioning:
"Who can tell me the three angles
on this set square?" (holding up
the 45°). "And on this one?"
(holding up the 30°/60°). This
checks initial comprehension.
Ensure learning intentions are
clearly understood by asking a
student to rephrase one in their
own words.
Differentiation (AEN):
Assessment: Observation:
Circulate the room during the
practice and
practical exercise. Check for
correct posture, grip, and use of
T-square/set square combination.
Provide immediate, individual
feedback.
"Show Me": After the
demonstration of combined
angles, ask students to quickly
draw a 75° line and hold it up.
This provides a quick formative
check of the whole class.
Peer-Assessment: Once the logo
is drawn, have students swap
with a partner and check for:
Student Practice: Basic Angles (5 mins)
Students practice drawing sets of parallel lines at 30°, 45°, and 60° on their paper.
Teacher Demonstration: Combining Set Squares (5 mins)
"Now for a clever trick. What if we need an angle that isn't 30, 45, or 60? We can combine our set
squares."
Demonstrate creating a 75° angle (45° + 30°) and a 15° angle (45° - 30° or 60° - 45°). Explain
the principle of addition and subtraction of angles clearly.
Practical Application: Microsoft Logo (20 mins)
Introduce "Practical Exercise 1: Microsoft Logo". Explain that this task reinforces the fundamental
skills of drawing precise horizontal and vertical lines, which are the basis of all technical drawing.
Step 1: "Use your T-square and a set square (in the 90° position) to draw a light 10cm x 10cm
square."
Step 2: "Divide this square into a 2x2 grid by drawing a horizontal and a vertical line through the
center (at the 5cm mark)."
Step 3: "Now, carefully colour the four squares: top-left red, top-right green, bottom-left blue, and
bottom-right yellow." (Note: The source
material incorrectly states blue for two squares, this is corrected to the actual logo colors for
accuracy).
1) Right angles
at corners, 2) Straight lines,
3) Neatness.
Differentiation (AEN):
For students struggling with
motor skills: Provide a
worksheet with the main 10x10
square pre-printed.
Their task is to add the grid lines.
For students who finish early
(Gifted & Talented): Challenge
them with the "Raised Garden
Bed Diagram" from the
PowerPoint, which requires more
complex use of
horizontal and vertical lines and
proportion. Alternatively, ask them
to try
and create a 3D version of the
Microsoft logo using 30° lines
(isometric projection).
Development
Conclusion
Quickly recap the main skills learned. "Today we've learned how to use 45° and 30°/60° set
squares to draw key angles, and how to combine them for more complex angles like 15° and
75°."
Refer back to the success criteria and ask students to self-assess their confidence with each
point using a thumbs-up/middle/down gesture.
Summative Quiz (5 mins):
Assessment:
The quiz results provide a clear
summative assessment of
individual student understanding
of the core concepts.
The homework assignment will
serve as a further assessment of
Administer the "Test Your Knowledge" quiz from the PowerPoint. Project the questions one by
one. Students can write answers (a, b, c, d) on mini-whiteboards or a small slip of paper.
Q1: Which of the following angles can a 60°/30° triangle be drawn directly? (b) 60°
