I teach boys middle school and it can be hard to find something they are interested in. This lesson worked quite well because they love baseball.
I introduced the topic and some vocabulary through "Take me out to the ballgame" and then we went over some vocabulary. There is a lot of vocab but it wasn't too much because the students knew many of the words already.
I ended the lesson by drawing a big baseball diamond on the board and dividing the class into 2 teams. I used magnets to represent the players.
I had one student come up as a pitcher and one batter from the other team. The pitcher drew a "what am I?" card and read the 3 clues one at a time and the batter had 3 chances (strikes) to guess the answer. The pitcher is changed after 2 pitches to give more students practice. Basically, the game goes until 3 outs and the teams change places.
I found some of my "who am I?" cards were a bit hard- so make sure to look through them and adjust to your class'' level. Also, make sure there are enough "home run" and "out" cards to keep the game moving more quickly
Enjoy!
