CSSE-Style Maths Mock 2 (Essex)
The CSSE-Style Maths Mock 2 (Essex) gives further practice at the Essex Consortium of Selective Schools' Maths paper format, covering the Key Stage 2 curriculum with a mix of straightforward calculation and multi-step word problems. This set focuses on decimals, percentages and measurement conversion, testing whether a pupil can move confidently between different numerical representations of the same quantity.
Method
- When a question mixes decimals, percentages and measurements, convert everything into a single consistent form (for example, all money in pence, or all lengths in the same unit) before you start calculating.
- Learn the common percentage-to-fraction equivalents (50% = 1/2, 25% = 1/4, 10% = 1/10, 1% = 1/100) so you can find many percentages of an amount mentally rather than long-multiplying.
- For 'increase by' or 'decrease by' percentage questions, decide whether you need the new total (calculate the change, then add or subtract) or the change itself, since these are easy to confuse under time pressure.
- For measurement conversion, write out the conversion factor you are using (for example, 1 metre = 100 cm) before multiplying or dividing, to avoid converting in the wrong direction.
- Estimate your answer roughly before calculating precisely, so an answer that is ten times too large or too small (a common conversion slip) stands out immediately.
- Where a question has several steps, write each intermediate result clearly labelled, so if the final answer is wrong you (or an examiner giving method marks) can see exactly which step went wrong.
Worked example
A carpenter has a plank of wood 2.4 metres long. She cuts off 65 cm to make a shelf, then cuts the remaining wood into 5 equal pieces. How long, in centimetres, is each of the 5 pieces?
- Convert the plank length to centimetres: 2.4 m = 240 cm.
- Subtract the length cut off for the shelf: 240 - 65 = 175 cm remaining.
- Divide the remaining length into 5 equal pieces: 175 divided by 5.
- Calculate: 175 divided by 5 = 35.
- Final answer: each piece is 35 cm long.
