A bookstore orders 175 dozen pencils.  How many pencils are there in all?  Explain how you found your answer.

Who's Right?

Mrs. Gearhart and Mrs. Harris were both trying to solve this problem.

8 + 4 x 3 ÷ 6

Mrs. Gearhart thinks the answer is 6.  Mrs. Harris believes the answer is 10.  Who do you think is correct?  What mistake was made with the incorrect answer?  Write your response in complete sentences.  Write your names, or initials, at the end of the post so we can discuss later in class.

Find the Volume
