Mental Arithmetic Paper 10
Mental Arithmetic Paper 10 is the tenth in this series of full timed mental arithmetic papers, built from the same core skills, the four operations, fractions, percentages, and time or money conversions, that the mental maths sections of GL Assessment and CEM/CSSE 11+ tests test throughout, with fresh numbers so pupils keep practising recall rather than remembering earlier answers.
Before you start
Make sure you're comfortable with these topics first:
Method
- Treat this paper the same as earlier ones in the series, refreshing key number facts, times tables and simple fraction-percentage links before you begin.
- Read or listen to each question fully before starting to calculate, so you answer the question that was actually asked.
- Use the fastest mental method for the numbers in front of you, rather than a single fixed method for every question.
- Keep a steady, even pace through the whole paper, since spending too long on one question is what most often costs marks on questions later on.
- Write down only the minimum working needed to carry a result from one step of a question to the next.
- If you finish with time to spare, use it to revisit only the questions you were least sure of, not the ones you already answered confidently.
Worked example
A mental arithmetic question, read aloud once: 'Multiply 9 by 6, then add 15. What is your final answer?'
- Start with the multiplication: 9 x 6.
- Recall the times-table fact: 9 x 6 = 54.
- Now add 15 to the result: 54 + 15.
- 54 + 15 = 69.
- The final answer is 69.
