Colours and Ready-Made Shapes
Your drawing does not have to be plain. Pick a colour, make the pen fat, and ask for a shape by name. The turtle knows circles, squares, triangles and stars.
💡 The idea
The turtle has a coloured pen and some shapes it already knows how to draw.
- colour red changes the pen colour. Try blue, green, yellow, pink, purple and rainbow.
- width 4 makes a fatter line. The biggest is 20.
- circle 50, square 80, triangle 80 and star 60 each draw a whole shape.
- dot 20 puts a filled blob right where the turtle is standing.
- A shape leaves the turtle exactly where it started.
📘 Words to know
