Here's a brain teasers game for grades 2 & 3. I put the students in 6 groups. For some of the questions, hints are needed (giving partial answers or doing fill in the blank). I have pretty high level students, so this lesson was a perfect challenge for them.

For the bonus round, they wagered points (like Jeopardy).

Here are some of the answers:

Round 2:
1. forgive & forget
2. tongue in cheek
3. operation
4. man over board
5. I love basketball
6. You're under arrest

Round 3:
1. beautiful
2. middle aged
3. waterfall
4. I'm missing you
5. cat & mouse
6. banana

Bonus: 40 squares
