I agree that it was B. The Rise of Religion.

What was the answer?

Like decimals, charts, fractions, estimating. At least that is what I had in 5th.

If Jack has 2 pencils, and Mr. Youn has 30 times, that would mean you have to do 30 times 2, right? And then, the whole school has 200 times as many as Jack, so in order to find out how much pencils the whole school has, you must do 30 times 200.

No, 3rd graders don't get algebra. 4th can get those really easy ones such as 2*?=32. 5th is more of rounding decimals and things like that. Algebra doesn't come in until like 7th grade.
