Timed math drills build the quick recall of number facts - 7 × 8, 15 − 9, 63 ÷ 7 - that makes longer sums and mental arithmetic easy. Pick addition, subtraction, multiplication, division or a mix, choose the numbers (any of the times tables from 0 to 12, or ranges of whole numbers up to 9999), and race a 60-second sprint or work through a worksheet. Every answer is marked straight away, the misses can be practised again, and your scores are kept in this browser so you can see yourself getting faster.
Everything happens on this page: the problems are made and marked in your browser, nothing is sent to a server, and there is no sign-up or account. A worksheet can also be printed as a PDF with its answer key, for practice on paper.
- What are timed math drills?
- Short bursts of simple arithmetic answered against the clock - often a "mad minute": as many problems as you can in 60 seconds. The aim is not to work answers out but to know them, so that 6 × 7 comes back as fast as reading a word. Doing the same kind of drill every day and watching the score climb is how that recall is built.
- Do timed math drills help?
- For facts a child already understands, yes: regular short practice makes recall quick and automatic, which frees attention for the harder parts of a problem. A timer on facts that are still being worked out does the opposite and mostly teaches worry, so start untimed with the worksheet and its marking as you go, and bring in the clock once the answers are mostly right.
- What ages or grades are these drills for?
- Addition and subtraction facts within 20 are practised from about age 5 to 7, and in the US are expected to be fluent by the end of grade 2. The times tables and their divisions follow from about 7 to 9: US grade 3 expects every product of two one-digit numbers from memory, and England's Year 4 multiplication check goes up to 12 × 12. The number ranges take it further, so older students and adults can use it as an arithmetic speed drill or a mental-math warm-up too.
- How is a sprint different from a worksheet?
- A sprint shows one problem at a time and moves on the moment you type the right answer, so it measures speed: how many you get right before the time runs out, or how long a set number takes. A worksheet shows them all at once, like a page of sums, and is marked when you finish or the timer ends.
- Are my scores saved anywhere?
- Only in this browser, on this device: your last 50 drills are kept there so you can see your recent scores and personal best for each kind of drill. Nothing is sent to a server, and Clear my scores removes them. A private window keeps nothing once it is closed.
- Can I print a math worksheet with answers?
- Yes. Set up the drill and press Print a worksheet (PDF): the first page has the problems with lines for a name, the date and the score, and the second page has the answer key. Each press makes a new set of problems, so you can print as many different sheets as you need.
