Timed mental maths drills, speed arithmetic and number sense games — free and instant
These are speed drills, not lessons. Every game here is timed, free and instant, and all of them exist to move one thing: the gap between working an answer out and simply knowing it. That gap is called fluency, it is the bottleneck in almost all mental arithmetic, and it responds to daily practice faster than almost anything else on this site.
For a general arithmetic speed drill, use Arithmetic 60s (one minute, mixed operations) or Math Drills (thirty seconds, good as a warm-up). Both give you a single number to track.
For multiplication specifically, Times Tables Sprint. Multiplication recall is the bottleneck in most larger calculations, and it is pure repetition — there is no technique substitute.
For addition only, Mental Addition. A mixed drill gives you a fraction of the addition reps a dedicated one does.
For reasoning rather than speed, Countdown Math and Equation Builder. Both run the arithmetic backwards — you search for a route to a target instead of computing an answer, which is much closer to real problem solving.
For number sense rather than calculation, Number Compare, Dice Count and Biggest Number. These target the instant, pre-verbal sense of quantity that sits under arithmetic.
Work left to right, not right to left. On paper you carry from the units; in your head, 47 + 38 is easier as 70 then plus 15. You get a usable approximation early and never hold a carry.
Round and correct. 47 + 38 becomes 47 + 40 − 2. This one habit accounts for most of the difference between fast and slow adult mental arithmetic.
Learn the shortcuts that actually pay: ×9 is ×10 minus the number; ×5 is halve then ×10; ÷5 is ×2 then ÷10; ×11 for a single digit is that digit doubled.
Practise division deliberately. It is the slowest operation for nearly everyone, and a mixed drill will not give you enough of it to improve.
Most people gain a third or more on a timed drill within two weeks of short daily runs, then improvement slows sharply. That first jump is almost entirely recall becoming automatic rather than any change in reasoning.
We do not publish an average score to compare yourself against, because scores depend heavily on problem mix and timer length, and a number from a different drill would be misleading. Your own first run is the benchmark that means something.
Warm up with one throwaway run. Cold first runs are consistently the worst of any session, and treating one as your score will mislead you about your own progress.
Yes, and in a specific way: fluency frees attention. If 7×8 arrives rather than being computed, the attention you would have spent computing it is available for whatever the multiplication was part of. That is the real payoff, and it is why fluency is worth practising even though it looks like the least interesting part of maths.
It will not teach you algebra, geometry or anything conceptual. These are drills for the recall layer, and they are honest about that.
A timed run of arithmetic problems where the goal is answering as many as possible rather than working carefully. It trains recall speed rather than method, which is why it is timed.
Yes, all of them, with no signup and nothing to install.
Compare against your own first run rather than a published figure — scores depend heavily on the problem mix and timer, so a number from another site would not be comparable. Most people improve by about a third within two weeks of daily runs.
Times Tables Sprint, and Math Bingo if you want the search element as well. Both force genuine recall rather than slow derivation.
They help with the fluency part, which frees attention for the reasoning part. They do not teach any new concepts.
