### Clock Flowers on Scratch

After some class work on clock flowers last week, I wrote a little bit of code on Scratch to make some more. You can make "petals" for the flower that have jumps of between 1 and 22. Try it out. Click the green flag to begin.

What do you notice?
What do you wonder?

1. What I noticed in 7,s: The petals of the flower go around 7 times.
It looks amazing.

2. 10 and 12 are almost the same!

1. Yes, six petals, five petals!

3. The odd numbers go to every stop.

1. I do not think so, because 15 is a odd number and it does not meet every stop

4. I really enjoyed Looking at all the prime numbers.

5. 7 goes to all the numbers because it is a prime number and prime numbers can only be timed by the 1 times table and it self times table.

6. Super cool blog, my favourite number was 14 at the start had ribbon affect .

1. I see what you mean, Noah; yes some of the patterns look better before they're finished!

7. 20 is only 2 jumps!

1. Annie, is it? Check again...

8. I notice that all of the prime number under 22 meet all of the numbers under 59 on the clock.It looks so cool!

1. What you say is almost true, Justus, but what about 2, 3 and 5?

What do you think?

2. 3 5 7 do not visit all of the numbers because are the factors of 60

9. Lets say the prime numbers are people and they like to visit every country in the world

1. I like that comparison a lot Gracia!

10. I really like the way some of the odd numbers carry on for lots of rounds. Just the way like 19,13 and so on.They look really amazing.

11. 19 and 21 are almost the same

1. Do you think so? Have a look again. I think there are more similar pairs than that. What do you think?

12. I notice that some numbers do not fit in 60 so they go round until it fits in.

1. Well noticed, Marie!

13. 19 and 13 go around to make lots of amazing paterns.

14. I notice that number 7 goes around 7 times

1. Awesome! Do any other numbers do that?

2. All the prime numbers up to 59 do the same amount of times.

15. Every prime number under 22 meets to every number even all of the prime numbers till 59 in the clock.

1. What you say is almost true, Samyak, but what about 2, 3 and 5?

What do you think?

2. 2,3,5 are factors for 60 so they don't work

16. Most of the PRIME NUMBERS make amazing donut shapes.

17. That game helped me

1. How did it help?

2. It helps because if you didn't know how many times a number goes round a clock you can count until you know it.

3. It also helps in multiplying. So, 17 X 3 = 51, you see that on the clock.

4. I noticed something with all the prime numbers except 3,5,7.17 is a prime number so it goes 17 times round passing 0 that is the same for all prime numbers.

5. Well noticed, Samyak! (You meant except 2, 3 and 5 of course.)
