This worksheet is for students to practise sketching transformations of the graph of y = lnx, particularly combined transformations. Students often get confused with the order of combined transformations - the teacher notes at the end of the worksheet set out an easy method for ensuring the transformations are done in the correct order. Answers are provided - graphs done in Desmos - but please comment if you spot any mistakes.

This is a worksheet on perpendicular lines, with solutions included. It is intended for GCSE but might be useful in C1 too.

This is a worksheet for C1 students studying indices. It covers simple exponential equations of the type where you make the bases the same and set the exponents equal to each other. Requires knowledge of index laws and factorising quadratics but not logs. Answers provided. May also be suitable as extension work at GCSE.

In this activity pupils calculate the median and mean of three data sets and consider whether mean or median is the better measure of location in each case. This prompts class discussion about the impact of outliers in a data set. A number of other discussion points may arise - see notes. This activity could be used at the start of a lesson on skewness. A word copy is attached for editing if required.
