Turn through bigger angles and draw stars with Logo.
This is the second in a twelve part introduction to Logo for beginners. In this part you learn to draw polygons.
Exploring balance and centres of mass can be great fun. The
resulting structures can seem impossible. Here are some images to
encourage you to experiment with non-breakable objects of your own.
Follow these instructions to make a three-piece and/or seven-piece
Logo helps us to understand gradients of lines and why Muggles Magic is not magic but mathematics. See the problem Muggles magic.
Arrange your fences to make the largest rectangular space you can. Try with four fences, then five, then six etc.
Make an equilateral triangle by folding paper and use it to make
patterns of your own.
More Logo for beginners. Learn to calculate exterior angles and draw regular polygons using procedures and variables.
Make a cube with three strips of paper. Colour three faces or use
the numbers 1 to 6 to make a die.
Make a mobius band and investigate its properties.
Have you noticed that triangles are used in manmade structures?
Perhaps there is a good reason for this? 'Test a Triangle' and see
how rigid triangles are.
It might seem impossible but it is possible. How can you cut a
playing card to make a hole big enough to walk through?
Learn how to draw circles using Logo. Wait a minute! Are they really circles? If not what are they?

Using these kite and dart templates, you could try to recreate part
of Penrose's famous tessellation or design one yourself.
Surprise your friends with this magic square trick.

More Logo for beginners. Now learn more about the REPEAT command.
Time for a little mathemagic! Choose any five cards from a pack and show four of them to your partner. How can they work out the fifth?
How is it possible to predict the card?
Have a go at drawing these stars which use six points drawn around
a circle. Perhaps you can create your own designs?
You could use just coloured pencils and paper to create this
design, but it will be more eye-catching if you can get hold of
hammer, nails and string.
What happens when a procedure calls itself?
Can you puzzle out what sequences these Logo programs will give? Then write your own Logo programs to generate sequences.
Learn to write procedures and build them into Logo programs. Learn to use variables.
In this article for teachers, Bernard uses some problems to suggest
that once a numerical pattern has been spotted from a practical
starting point, going back to the practical can help explain. . . .
Learn about Pen Up and Pen Down in Logo
Write a Logo program, putting in variables, and see the effect when you change the variables.

equilateral and isosceles triangles? Can you make a square?
Follow the diagrams to make this patchwork piece, based on an
octagon in a square.
Draw whirling squares and see how Fibonacci sequences and golden rectangles are connected.
Can you describe what happens in this film?
This part introduces the use of Logo for number work. Learn how to use Logo to generate sequences of numbers.
Paint a stripe on a cardboard roll. Can you predict what will
happen when it is rolled across a sheet of paper?
Galileo, a famous inventor who lived about 400 years ago, came up
with an idea similar to this for making a time measuring
instrument. Can you turn your pendulum into an accurate minute
Follow these instructions to make a five-pointed snowflake from a
square of paper.
Can you order pictures of the development of a frog from frogspawn
and of a bean seed growing into a plant?

and work out a way they might fit together?
This practical activity involves measuring length/distance.
