Averages Crossnumber and Bingo
I made these resources for a job interview over eight years ago and have used them with every KS3 class I have had since.<br />
<br />
The crossnumber contains a mix of questions on mean, median and mode with an extension question to really make the pupils think. It's a great resource for either a 20 min segment of a lesson or a perfect homework sheet. It has self assessment built into by the nature of the exercise - the crossnumber will only work if all the 'across' and 'down' questions are answered correctly.<br />
<br />
The 'Average Bingo' is great plenary. Each student must draw a 5 by 5 grid in their exercise book and randomly place the numbers 1 to 25 in each box. You then read out the questions in a random order (remember to mark of the questions you have asked). The pupils then find the answer on their grid and cross it out. The first pupil to get a row wins. This resource can be used multiple times as each pupils grid is unique. I have attached two versions of the questions.
