- Write the first 20 multiples of 45.
- Do you see any patterns? Is there a shorter way to find them all?
- Place the last two digits numbers you found around the icosagon (20-sided polygon)
- Join the points in order of appearance.
- What visualization do you get, when you do the same process with 55?
- Do the same procedure with 35, 25 and 15.
- How about the multiples of 3? What polygon should you use?
