Street Maths
Have you ever been torn between art and maths?
Start your journey into Maths Art with our step-by-step designs.
Have a try on paper, blank or squared sheet.
Let’s brighten up the street, the playground, using chalks. And make an ephemeral piece of art!

Design #1: Star
Press the pencil gently enough to make a mark. To be able to erase some parts at the end.
- Built a square ABCD of side 12 cm.
- In the middle of the line segment:
- [AB] is I.
- [BC] is J.
- [CD] is K.
- [AD] is L.
- Draw the line segment [AJ], [AK], [AC], [BL], [BK], [BD], [CI], [CL], [DJ], [DI], [IK] and [JL].
- Erase the redish broken lines.
- Choose 3 colours and let’s paint!
From the book La géométrie pour le plaisir – J. & L. DENIERE
Design #2: Rhythm & Colours
From a painting of Robert Delaunay (1885 – 1941) showcased at Pompidou Centre (in Paris) Rythme sans fin – Infinite Rhythm, 1934.

Design #3: Infinite Squares
-
Built a square ABCD of side 10 cm.
-
Locate:
-
the point a on the side [AB] such that Aa=1cm.
-
the point b on the side [BC] such that Bb=1cm.
-
the point c on the side [CD] such that Cc=1cm.
-
the point d on the side [AD] such that Dd=1cm.
-
-
Join [AB], [BC], [CD] and [AD].
-
Locate:
-
the point e on the side [ab] such that ae=1cm.
-
the point f on the side [bc] such that bf=1cm.
-
the point g on the side [cd] such that cg=1cm.
-
the point h on the side [ad] such that dh=1cm.
-
-
Join [ef], [fg], [gh] and [he].
-
Do the same for the other squares mnpq, EFGH, MNPQ and urst (see other pictures).
-
Choose a gradation of some colour or just 2 colours and let’s paint!
Have fun! Try to change the gap (1/2 inch; 1 inch; 0,5 cm; 2 cm…). Try to change the direction of the rotation.
Design Halloween: Spider Web
- Built a square ABCD of side 12 cm. Draw its diagonals [AC] et [BD].
- Place:
- I in the middle of the line segment [AB]
- J in the middle of [BC]
- K in the middle of [CD]
- L in the middle of [DA].
- Then draw the line segment [IK] and [JL].
- Place:
- M in the middle of the line segment [AI] and Q in the middle of [KC]. Draw the line segment [MQ].
- N in the middle of the line segment [IB] and R in the middle of [DK]. Draw the line segment [NR].
- O in the middle of the line segment [BJ] and S in the middle of [LD]. Draw the line segment [OS].
- Place P in the middle of the line segment [JC] and T in the middle of [AL]. Draw the line segment [PT].
- Through J, find the perpendicular segment of [OS], which cuts [OS] at U. Draw the line segment [JU].
- Through U, find the perpendicular segment of [BD], which cuts [BD] at V. Draw the line segment [UV].
- Go on, always in the same direction.
- Do the same perpendicular line drawing from I, L then K by turning always in the same direction.
