Jared’s mom works for a company that publishes books. When he visits her office, he likes to watch the machine that binds the books. Mr. Green, who runs the machine, told Jared that the machine can bind 12,000 books in 1 hour and 20 minutes and that the machine runs steadily for 10 hours every day. He also found out from Mr. Lee in marketing that last month, the company printed fiction and non-fiction books in the ratio of 4:1, with 540,000 more fiction books printed than non-fiction. Jared’s mom asked him if he could use all the information he learned to figure out how many days it took last month to bind all the fiction and non-fiction books that were printed. Does he have enough information? If so, how many days did it take? If not, what other information does he need?

A Great Problem for Mathspot.Net
I found this problem on Mathspot.net, a great blog by Lisa Englard and really liked it. It was co-written by Lisa and first appeared in Teaching Children Mathematics, Math by the Month column, October 2013. It is here with Lisa's permission.

Two Step Problem Solving with Second Grade
I love working with kids...and when I can't do it in person, I do it by email and sometimes, even, skype! Theresa Trevino is an amazing second grade teacher in Houston, TX. I saw a version of this problem at NCTM this week and wondered how her second graders would handle it. Next week, I'm hoping to skype in and talk to them about it!
The problem reads
A zoo has 7 camels and some giraffes in a big corral. There are 15 animals in the corral. Then they got 4 more giraffes. How many giraffes are there now?
You can see more solutions and some video clips by visiting Theresa's blog!
