Lesson on Maths skills needed for the new Combined Science GCSE (9-1) with a focus on Biology content, although many of the skills are needed across all three Sciences. The lesson is intended to be a circus activity with all of the topics around the room (information sheet and exam question sheet for each that I printed back to back) for students to move around between and then mark at the end of the lesson. It could easily be done as a teacher lead lesson as well though and even slotted into other lessons as needed. The maths skills included are: Comparing Data Analysing Graphs Drawing Tables Calculating the Mean Mode & Median Calculating Percentages Calculating Percentage Changes Percentile Charts Converting Units Standard Form Ratios & Fractions Variation Magnification Equation Cardiac Output Equation BMI Equation Estimating Population Size Equation There is an information sheet and exam question sheet for each, as well as answers to all the questions.
