Instructions for the true-false game
Version 1
Play as an active moving about game.
All students move to the side of the classroom indicated as false this is the starting position. Make it clear that when the statements are shown there is no running and they must make a decision as they cannot stand in the middle.
Show the first statement and give a time limit count down the last 5 seconds.
Click again to reveal who is on the correct side.
Students on the wrong side sit down.
Continue until you have a winner.
Version 2
A game with students in their seats. Play in small groups (3 or 4).
Give students mini-whiteboards.
Show the first question give a time limit and students write true or false. Count down the last 5 seconds and students hold up their boards at the same time.
Each group with the correct answer scores a point and the group with the most points after all

Instructions for the speed-dating activity
Give each member of the class a question card.
Divide the class in half.
The first half of the class take their chair and sit around the edge of the room in a large circle.
The second half of the class take their chair and sit opposite one of the people already around the edge.
Allow 1 minute for students to ask each other their questions in pairs.
Call change and the second half of the class stand and move one seat in a clockwise direction.
Time is given to ask questions again.
Repeat the process until students in the inner circle are back to their original original
