BIDMAS – All – Disarm the Bomb – Clue Hunt This game involves students finding the 8 characters to disarm their team’s bomb. These characters can be found in posters placed around the classroom. Whether the calculations on the poster are true or false, combined with the notes at the bottom of each poster, tells the student whether a character is part of the code. Click/Touch ‘Arm’ to start each timer. Then a chosen student/the teacher can input the characters – in any order – and then click/touch ‘Disarm’. If this is not done in time, the bomb will explode. The correct code is in the ‘notes’ and on the answer slides. You can choose to use the normal 20 minute bomb – or a 10 minute bomb for a frantic game that requires excellent teamwork! You may want to delay arming the bombs. Delete the bomb-slides you don’t want to use. (Clear plastic wallets around your classroom make it quick and easy to display posters.) This game has sound!
