Mental maths is the ability to perform arithmetic calculations in the head, without paper or calculator. It is a practical skill used countless times every day, and it is a powerful indicator of mathematical fluency. Children who can calculate mentally are working from a well-developed number sense that benefits them across all areas of mathematics.
Why mental maths matters
Mental maths is not just about fast arithmetic. It is evidence of deeper number understanding:
Number sense: A child who can quickly calculate 47 + 38 mentally has internalised the structure of the number system in a way that a child who needs paper does not.
Estimation: Mental maths and estimation are closely related. A child who can mentally calculate approximate answers can check whether their precise calculations are reasonable.
Working memory efficiency: Mental calculation requires holding intermediate results in working memory while performing subsequent operations. Practising this builds the working memory skills that benefit all academic work.
Speed in complex problems: When solving multi-step problems, students who perform each step mentally rather than on paper reach solutions faster and with less effort, freeing attention for the harder parts of the problem.
Core mental maths games
Times Table Sprint is the most important game for mental maths development. Multiplication fact fluency is the foundation of mental arithmetic: a child who knows instantly that 7 x 8 = 56 can mentally calculate 7 x 48 much more easily than one who must derive 7 x 8 each time.
Mental Maths Race is specifically designed for mental calculation speed. It presents mixed arithmetic problems at increasing speed, building both fluency and the mental calculation habits that move beyond counting strategies.
Math Facts Blitz covers all four operations in a rapid-fire format that builds the all-round arithmetic fluency that mental maths requires.
Number relationship games that support mental maths
Number Bonds to 10 and Number Bonds to 20 build the foundational number relationships that make mental addition fast. A child who knows instantly that 8 + 7 = 15 (because 8 + 2 = 10 and then 5 more) is using number bonds in mental calculation.
Skip Counting builds the multiplicative counting patterns that bridge into multiplication fluency.
Estimation as mental maths
Estimation Game builds the complementary skill to exact calculation. Mental maths and estimation work together: estimate first to set expectations, calculate precisely, then check the precise answer against the estimate.
Children who practise estimation develop better mental arithmetic because they are building numerical intuition alongside procedural fluency.
Building mental maths speed
Mental maths speed develops through a specific progression:
- Accuracy first: Getting correct answers reliably before worrying about speed
- Strategy development: Learning efficient mental strategies (making tens, compensating, doubling)
- Strategy automation: Strategies become habits that no longer require conscious effort
- Fluency: Rapid, accurate, automatic mental calculation
Games that provide immediate feedback on speed and accuracy, like Times Table Sprint, work on steps 3 and 4. The earlier steps benefit from parent-led instruction alongside game practice.
Practical tip: For each new times table being learned, follow this three-phase approach: one week of Times Table Sprint focused on that table, one week of mixed practice including that table, one week of mixed practice across all tables. This progression builds specific fluency and then integrates it.
