Students were given 100 index cards and 100 cm of tape. They had to use these items to build a tower in 30 minutes. The tower that could hold the most weight won. We also had a 100 piece puzzle challenge. The group that could finish the puzzle the quickest won a prize. The students then wrote autobiographies about themselves, from the ages of 1 to 100. They had to make up some of the information for later on in their life. It's funny to see the things the students wrote. They were also given a picture of themselves that have been aged to make them look older.
