ALGEBRA BINGO Instructions Use scrap paper. Get students to draw a 3 by 3 grid and choose 9 values from the 20 that the teacher has written on the board. Students use pen to avoid cheating. Check their neighbour and initial before the start. Teacher photocopies clues and crosses out as they are called. Change any clue that is too difficult for your class. Teacher decides whether to reward lines or wait for a total bingo. It can be encouraging to offer prizes for the first 4 or 5 lines and then go for total bingo. Teacher Note: There is a certain amount of vocabulary involved when clues are read aloud. It becomes apparent which words are confusing for the students and the teacher can focus on this in future lessons. Extension: Students can make up clues which they give to the teacher. They write the answer on the board and the class selects the answers for their bingo board. The teacher draws their clues out of a box. Aim: To practise simple algebra addition, subtraction, multiplication and division. Teacher writes on board and students choose 9 from: x 2 2 2 2 2 3 3 3 4 4 5 6 , x, 2x, 3x, 4x, 5x, 6x, 7x, x , 2x , 3x , 4x , 6x , x , 2x , 3x , x , 4x , x , x 2 Clues: Read out in random order and cross out as you go. x What is 5x divided by 10? 2 What is 5x divided by 5? What is x + x? What is x + x + x? What is 2x + 2x? What is 10x – 5x? What is 4x + 2x? What is x + 6x? What is x multiplied by x? 3 What is 2x divided by x? 3 What is 3x divided by x? What is 2x squared? What is 3x multiplied by 2x? What is x squared multiplied by x? 4 What is 2x divided by x? What is 3x multiplied by x squared? What is x squared squared? 8 What is the square root of 16x ? 4 What is x multiplied by x? What is x squared raised to the power of 3? x 2x 3x 4x 5x 6x 7x 2 x 2 2x 2 3x 2 4x 2 6x 3 x 3 2x 3 3x 4 x 4 4x 5 x 6 x
