Today I gave the students the opportunity to finish the Four 4's problem from yesterday. My plan was to give them about half the class to finish and share, but they were working so hard on it I decided to let it run through the entire class period.
I like to write my date as a math problem that needs to be solved, so today I wrote the date as August 4!+2. This introduced or reminded the students of the idea of factorials which are helpful in solving the Four 4's problem. After they had a chance to work in groups to get as many numbers as possible, I gave each group a poster paper to write their solutions and post around the room. I then had the students do a gallery walk, where they got to check 10 problems. They put a star next to it if they agreed with the solution, or they wrote a comment on a sticky note if they disagreed. Finally, students got to look back over their poster and correct any mistakes that were found. The students came up with some very clever ways of solving these problems. Here are some of the posters:
