This is a competitive, group activity where students are challenged to compose strong topic sentences.
Divide the class into 7 groups. Create 10 stations, each with one of the numbered worksheets. Each group is assigned a team letter where they will write their topic sentence. The team writes a strong topic sentence based upon the weak topic sentence at the top of the page. They will begin at the numbered station you assign them to and then move up one number at each timed break. The team at station 10 will go to station 1 and so on, until each team has completed each station. The teacher will then pick a winner on each page. The teacher reads the winning sentence to the class, and then the class explains the characteristics that lead to it to be chosen.
