For this game, you will need eight bushel baskets or similarly sized containers, 10 beanbags, duct or masking tape, 10 chairs, eight sheets of plain white paper, a thick-tip marker, a computer or overhead projector, a screen and an empty room. You will also need approximately 30 sentences with a mixture of types, which you will display either with the computer or overhead projector one at a time. Do not turn the lights off in the room during the activity -- dimming those around the screen should be enough.
Arrange four chairs in rows on both sides of the room, spacing them out by one foot. Tape the bushel baskets to the back of the chairs. Write the name of each type of sentence on two pieces of paper and tape a set of each to the seats of both sets of chairs. Make a line of tape two or three feet away from the middle of each row and put a chair beside it. Place five beanbags on each chair.
Split students into two teams. Each team will send up one member at a time to the tape line on either side of the room. Display and read them a prepared sentence. Both students will try to throw a beanbag into the basket indicating the type of sentence they read. Whoever gets a beanbag in the correct basket first gets a point for his team and the team with the most points at the end is the winner.
This game requires a bit more non-academic skill than most in-school games, but this strongly improves students' motivation to participate. It also helps students associate learning about grammar, which many of them find nebulous and difficult, with a fun and exciting activity. However, if you find that students are becoming frustrated because of misses, you can decrease the difficulty by moving the line closer to the baskets. The point of the game is to get students excited and engaged while they learn, but if the challenge defeats the purpose it, alter it.
