## Counting Spirals

Question 1:
Approximately how many clockwise spirals does the above pinecone have?
The picture on the left has one (aqua) clockwise spiral highlighted.
Question 2:
Approximately how many counterclockwise spirals does the above pinecone have?
The picture on the right has one (black) counterclockwise spiral highlighted.
Question 3:
To estimate the spirals in flowers with many of them,
perhaps you want to count a part of the flower, and then estimate how many regions there are of

spirals in 1/4 of the flower and multiply by 4.**
Approximately how many clockwise spirals does the following flower have?
The picture on the left has one (aqua) clockwise spiral highlighted.

**Don't

Question 4:
Approximately how many counterclockwise spirals does the above flower have?
The picture on the right has one (black) counterclockwise spiral highlighted.
