A puzzle linking areas of rectangles with the factorisation of quadratic polynomials designed to develop fluency and problem solving skills.

A big A3 sheet that links up all the different things you can do with quadratics including:<br /> - Finding the Equation<br /> - Finding the y-intercept<br /> - Finding the shape<br /> - Discriminant<br /> - Factorisation<br /> - Roots<br /> - Completing the Square<br /> - Max/Min<br /> - Sketch<br /> <br /> And linking them all to one another in different ways. It is quite tough in places, but very satisfying to solve.

Find the correct inverse of the displayed function from the four choices. Only one is ever correct, and the others are designed to find misconceptions. Slides are timed and move on automatically.<br /> <br /> It is deliberately similar to a Kahoot quiz, as I can't figure our how to display decent mathematical notation on there, but like the way it is done generally.<br /> <br /> Answers included at the end.

A slideshow with automatic transitions and timers on each screen. The answers to the questions on each slide are the same.<br /> <br /> There are 15 slides, each with 3 different levels of question (bronze, silver, gold), which get gradually harder.<br /> <br /> Each slide has a minute countdown, and changes automatically to the next when it is done.<br /> <br /> The questions include simple linear equations (e.g. x+4=9), to questions with variables on both sides.<br /> <br /> The scoring system I used gave more points for harder questions, but there is also the jeopardy of getting them wrong. Points for method were also given.<br /> <br /> My year 7s quite happily did this in silence for 15 minutes at the start of a lesson, but the last few questions were definitely a bit tricky for most of them.

You can choose how many coins you want to flip (up to 10), and whether you are interested in Heads or Tails. Press Flip, and the spreadsheet will count up how many there are and graph the distribution created.

A spreadsheet that randomly rolls four dice and counts the number of 5s in each trial, graphing them as it goes along.<br /> <br /> The second version (different choices) allows you to change the number that gives a successful trial.
