- Prepare questions for revision. Questions can be asked orally or written on the board as you ask or, if possible, prepare on an OHP or Interactive White Board (see example 1).
- Draw a grid on the board (see example 2).
- Draw another grid on a separate page and add 4 "chocolate bars" horizontally or vertically (see example 3).
- Optional reward: real chocolate bar/s for the winning team.
- Put the students into teams of 3 or 4.
- Either get each team to think of a name for their team (They love this!) or give them a name e.g. Team A, B etc.
- Draw a chart with the team names on the board next to the grid.
- Tell the students that you have hidden 4 "chocolate bars" in the grid and they have to guess where they are.
- Tell the students that there are 4 bars of chocolate of different sizes hidden horizontally and vertically in the grid.
- Explain that each team will get a turn to answer a question and if they get it correct they will have a turn at guessing where the chocolate bars are. Students guess by calling out "A1" or "B3" for example.
- The teacher can reply by saying "You've got a square!" or "Better luck next time!"
- The team will get a point for every square of chocolate they find.
- The team with the most points at the end is the winner.
