Coloring tips
How to color triangle
Triangles come in three flavours: equilateral (all three sides equal), isosceles (two equal), and scalene (none equal). Try filling each side or corner with a different colour to highlight the three-ness of the shape. A triangle with a green base and a brown trunk becomes a tree in a single step.

Fun facts to share while you color
Read these out loud — a 20-minute coloring session doubles as a real lesson.
Every triangle has three angles that always add up to exactly 180°.
Triangles are the strongest shape — that's why bridges, roofs and bicycle frames use them.
An equilateral triangle has three equal sides; an isosceles triangle has two; a scalene triangle has none.
The Egyptian pyramids are built from giant triangular faces.

Square coloring pages
A square is the most stable shape — four equal sides, four right angles, every corner the same. Squares appear everywhere in everyday life: windows, books, picture frames, board games. They're the easiest shape to draw after the circle and the first shape that introduces the idea of equal sides.
Rectangle coloring pages
A rectangle is a stretched-out square — four sides, four right angles, but only the opposite sides match in length. Doors, books, beds, TV screens and bills of money are all rectangles. It's the most useful shape in everyday design because rectangles tile flat surfaces without leaving any gaps.
Circle coloring pages
The circle is the friendliest shape — no corners, no edges, no wrong way up. It's usually the first shape kids can draw on their own and the easiest to fill in inside the lines. A single circle becomes a sun, a face, a balloon or a clock face with almost no extra work.
Star coloring pages
The five-pointed star is one of the most recognisable shapes in the world — it appears on more national flags than any other symbol. Drawing a star is a small rite of passage for kids who can write: five strokes in a single flowing motion. Each of the five points is a small triangle waiting to be coloured.
Diamond coloring pages
A diamond is a square balancing on one of its corners — the same four sides, just rotated 45 degrees. It's also the geometric symbol for a sparkling gem. Diamonds are common in playing cards, kites and the warning signs on the road, which makes them surprisingly easy for kids to spot.
Oval coloring pages
An oval is a circle that got pulled wider — the same smooth, cornerless edge, just stretched into a longer shape. Eggs, faces, racetracks and many leaves are ovals. It's a great 'next step' shape for kids who can already draw circles and want a small new challenge.
