Four problems taken from edexcel exam papers where algebraic techniques are needed to find expressions for area or volume. Diagrams and answers given in ppt. Word document contains two levels of scaffolding for each problem - first level breaks the problem down into steps and the second level gives more detail about each step. Used initially with the problem on the front of a coloured card (green for first two, amber for third and red for fourth to indicate level of complexity) and the scaffolding stuck onto the. Used with year 9 top set to finish off FOIL but equally useful for yrs 10 and 11

A short activity designed to revise plotting scatterdiagrams, calculating the correlation coefficient and the y-on-x regression equation. Moves on to comparing these results for coded sets of data. Includes brief teacher's notes and an autograph file for each set of data.
