OBJECTIVES:
Develop number sense
Introduce number theory
Practice sums of ten

MATERIALS:
Worksheets
History of the Shamrock
pencils
markers
video about the history of St. Patrick's Day

1. That's really cool! I didn't even realize it had made the shamrock shape until I started reading!

Do you remember getting string-art kits? Are you old enough to remember those? :)

2. That is too cool!!! My Dad used to say Math was the universal language :)

Happy H.O.T day :)

3. wow ... interesting! am not much into math, but hubby is ... he'd try to get into this right away if he'd get his way! :)

4. That's pretty interesting. When I first saw it though it reminded me of a design that was created using one of those old "spirograph" things. I used to have one when I was a kid and had fun drawing lots of different designs with it. Good post for the meme.

5. I am such an idiot....I saw the picture and thought okay green lines. It took me a minute looking at it to see the shape. Blond moment I guess hehe!

6. There appears to be a lot of math involved. I see a graph and numbers.

My kind fears math. And math-related activities.

THIS BLOG IS WITCHCRAFT! IT IS IN CONGRESS WITH THE DEVIL!!!

j/k have a great tuesday

7. This is really cool! I love all the different takes people come up with! It's awesome!

8. How cool. Is this something that always interests you, or is it a St. Paddy's Day treat?

9. Wow!!! Quite cool.

My HoT 'green' is shared. I do hope you can drop by, if you haven't already. Be prepared to sing along with Kermit the Frog tho!! :::smiles:::

10. Too cool! I thought of string art at first, too, but this is so much more. I've bookmarked this to follow some of the links and read more. Thanks, Andrée.

11. Incredibly interesting and cool! :) What a great way to promote math! :)

12. This is so cool, amazing...wow!

13. What a great take on the green theme! I am going to show my children your post.

14. I guess I should be proud of myself because I saw the shamrock shape right away ;-) What a very unique and fun post!

15. Wow! That's pretty impressive - Nifty post!

I love this post. I was always math and science phobic as a kid, but I've realized recently that it was silly. I may never be good at math, but it sure it intriguing, isn't it?
