Activity type: Working out a ‘cocktail stick’ puzzle /pair work
Age: Adults or senior YLs
Take a box of cocktail sticks into the classroom. Arrange students around a central space with a table.
- Use the cocktail sticks to make simple geometrical shapes and symbols. Point to each shape and ask What’s this? Elicit an answer orally each time. Suggested shapes: A square, a triangle, a rectangle, a cross, a star, a diamond, a hexagon, etc.
- Appoint a student to be your helper. Tell students that you are going to explain how to make a star shape with the cocktail sticks. Each time students hear a verb they should repeat it and the helper should write it on the board.
- Make a star shape with the cocktail sticks, giving simple ‘instructions’ as you make each move. Use as many different verbs as possible. Use affirmative and negative examples. E.g. Take a cocktail stick, place it here, put it there, pick up this cocktail stick, add another cocktail stick, don’t move the other cocktail sticks, join these two sides, take away these two sticks, etc.
Part 1: Model the activity
- Tell students they are going to do a puzzle. Make this shape using 12 cocktail shapes.
- Write the ‘puzzle’ on the board.
- Remove two cocktail sticks so that there are only two squares left.
- Tell students to think carefully about how to solve the puzzle and to think carefully about the language they need to explain the solution. Elicit the answer orally. Students can point at cocktail sticks and give clear instructions to solve the puzzle. But they shouldn’t do any of the actions themselves.
Part 2: Students work in pairs, trying to solve another puzzle together and then each pair of students works with another pair, to explain and check their ideas.
- Put students into pairs to work together. Give half the pairs handout A, and the other half handout B. Have a group of three if necessary to make an equal number of pairs.
- The pairs follow the instructions on their handouts. First they try to solve their own puzzle together, making suggestions. Then they discuss (or make notes) about the language they need to use to explain the solution to the other puzzle.
- Then Student A pairs get together with Student B pairs. Students A explain which moves need to be taken to solve their puzzle. Students B (who have the ‘solution’) listen and tell them whether they are correct. Then pairs change roles and Students B explain how their puzzle can be solved.
- Note: Leave the list of verbs on the board for students to refer to.
