Flashcards are placed in a row, and positive and negative numbers are written randomly above each of them (between -3 and +3). A magnet is placed over the first card, as the class’s ‘ohajiki’. Students repeat the teacher as they call out the target English within a time limit. When the timer goes off, the teacher rolls a dice. Whatever number is rolled, the magnet is moved forward that many spaces. Depending on the number that is above the card they land on, points are added to or subtracted from the class’s score. If the number rolled moves the magnet beyond the last card in the row, move back to the first space and continue.
