A 2-session design unit for high school. Students discover that the cleanest logos are not drawn freehand but constructed — built from circles, a grid, and a few guides so their proportions are deliberate and repeatable. Then they learn the secret designers rarely say aloud: the math has to be quietly broken so the mark looks right to the eye.
A mark built, not sketched. Faint circles and grid lines set the proportions; the bold form is locked to them — so it can be rebuilt exactly.

Learning objectives
By the end of the unit, students will:
Explain why a constructed logo is more consistent and reproducible than a freehand one
Build a simple mark from a grid, circles, and geometric guides
Apply optical corrections — overshoot and weight adjustments — so shapes look balanced
Test a logo at small and large sizes and simplify where detail fails
Critique a mark for proportion, balance, and clarity
Standards alignment

Materials
Internet-connected device per student to study the logo-construction overlay and build the mark
A compass, ruler, and grid or graph paper for the construction
Pencils, a fine black pen, and an eraser; optional design app or vector tool
A short brief — a name or initial and one idea the mark should suggest
Printed examples of constructed logos with their guide circles visible
Lesson sequence
1
Building a mark from geometry
45 minutes
Warm-up · 5 min
Show a famous logo with its construction grid revealed — circles and lines under the final shape. Ask "Was this drawn by hand or built?" The reveal lands: the cleanest marks are engineered. A grid is what lets a logo be redrawn identically at any size, forever.
Main activity · 30 min
(4 min) Students pick a simple subject — an initial, or a basic icon like a leaf, a bird, or a mountain — that can be reduced to a few clean shapes.
(5 min) They open the logo-construction overlay and study how circles and a grid set the curves and proportions of an existing mark.
(14 min) On grid paper, students draw construction guides first — a bounding box, a few circles for curves, lines for stems — then trace the mark on top so every curve has a center and every edge a coordinate.
(5 min) They strip the mark down: remove any line that is not doing a job. A logo must survive being tiny, so simplicity is built in now.
(2 min) Students keep a copy with the guides showing and a clean copy without, to compare tomorrow.
Guides, then trace, then clean. The construction stays invisible in the final mark but guarantees it can be rebuilt exactly.
Reflection · 10 min
How did building from guides change the way your shapes related to each other?
What did you remove to simplify the mark, and did it get stronger?
Why does a logo need to survive being printed the size of a thumbnail?

Refining and applying optical corrections
45 minutes
Warm-up · 5 min
Show a circle and a square drawn to the same height side by side. Most students say the circle looks smaller. It is the same height — but the eye shrinks round shapes. This is why designers make circles slightly larger than the math says: today's twist is that perfect geometry can look wrong.
Main activity · 30 min
(8 min) Optical corrections: students overshoot round and pointed parts slightly past the guides so they read the same size as flat parts, and check that stroke weights look even rather than measure even.
(10 min) They redraw the mark with corrections, comparing it to the strictly geometric version. The corrected one looks more balanced even though it is less mathematically pure.
(8 min) Scale test: students draw the logo at thumbnail size and at large size. Anything that breaks small gets simplified.
(4 min) They produce a final clean black version with no guides, ready to use.
Optical correction: the circle is drawn slightly past the guide lines so it reads the same size as the square. The eye, not the ruler, is the judge.
Reflection · 10 min
Where did you have to break the geometry to make the mark look right?
What happened to your logo at thumbnail size, and how did you fix it?
Why might a designer trust their eye over the measurement?
