GCSE Maths 9-1 Density, Mass and Volume
At Ilkley Tuition we offer expert GCSE Maths tuition in Ilkley as well as recommendations to the very best GCSE Maths resources. This week we are looking at the density, mass and volume question types which have come up quite a few times in the GCSE Maths specimen papers and also in the 2017 GCSE Maths exams for OCR, AQA and Edexcel.
Density, mass and volume questions often require students to convert units, rearrange equations and use algebra substitution to finally work out the correct answer. The questions are usually worth two or three marks and are considered around a level 4-6 question type depending on the amount of complexity and the number of steps required to find the solution. It is a nice question type in the context of the new GCSE Maths exams, simply because the formula is given at the start of the question making the question type easy to identify which is often much of the difficulty with the new style GCSE Maths questions. As there are only a few different ways of asking the density questions, it is a good question to revise and memorise the method. The most common mistake on density questions is the incorrect units are often used or students have failed to complete the conversion required.
