## Main Idea and Supporting Details

1.
The Babylonians were the first to set the measurement of a full circle at 360 degrees. They reasoned that the most important circle is the revolution of the earth around the sun, a period of time which we call a year. They knew that a year was approximately 365 days. However, the number 360 is much more convenient for mathematical computation, since it is divisible by many factors-- among them, 2, 3, 4, 5, 6, 8, 9, 10, and 12.

Wow! What a great trip to the zoo with my family. Everything was so exciting, except for the giraffe. It licked me on the face when I was trying to feed it. Yuck! Even though that was bad, I loved seeing the monkeys. My teacher has a book about monkeys in her classroom. They were swinging from branch to branch chasing each other. It was like they were playing tag. My favorite part of the trip was when we got to touch the sting rays.
