⏱️ Mental Maths for Kids: Speed Drills and Worksheets

What these mental maths activities are

Mental maths means working out an answer in your head, without a calculator and usually without writing down long steps. The drills on this page give children a short burst of practice: a set of sums appears, a one minute timer runs, and the child answers as many as possible. At the end, the score is shown so children can try again and improve.

• Mixed Mental Maths Drill — addition, subtraction and simple number facts together, so children must switch between operations.
• Addition and Subtraction Speed Drill (to 20) — focused practice with small numbers, ideal for early primary classes.

Both activities are free, repeat with fresh sums each time, and can also be printed as a worksheet.

Skills children build

Short, regular drills do more than test memory. With a few minutes a day, children begin to recall number facts instead of counting on fingers, which frees up thinking space for bigger problems later.

• Number fact recall — pairs that make 10, doubles, near doubles and simple subtraction facts.
• Speed and accuracy — working quickly while still checking the answer.
• Concentration — staying focused for one full minute is a real skill for young learners.
• Confidence with tests — a timer feels friendly here, so classroom timed tests feel less stressful.
• Self-measurement — children compete with their own last score, not with classmates.

How to play online and how to print

To play online, open an activity, press start and type or tap the answers. The timer runs for one minute and the score appears at the end, so children can immediately try for one more correct sum than last time. It works on touch screens and with a keyboard.

To use the printable version, choose the print option and you will get a clean black and white worksheet with the same style of sums. Printed sheets are useful for travel, homework folders, revision before a test, and classroom practice when devices are not available. Teachers can print one set for the whole class and time everyone together with a wall clock.

Ideas by age

Ages 4 to 5 (preschool and kindergarten): the timer can wait. Let children answer at their own pace, or use the printable sheet and solve a few sums together using counters or buttons. Children who are still learning numbers will enjoy counting games and addition with pictures first, where answers are shown with objects.

Ages 6 to 8 (Class 1 to 3): this is the sweet spot for speed drills. Start with addition and subtraction to 20, aim for five to ten correct answers in the first week, then build up. One drill before homework works better than a long session once a week.

Ages 9 and above: use the mixed drill as a warm up. Ask children to record their score in a notebook and look for a weekly pattern, or to explain the strategy they used, such as making a ten or using a known double.

Tips for parents and teachers

• Keep it short. One or two minutes a day beats a long weekend session.
• Praise the strategy, not just the score. Ask "how did you work that one out?"
• Allow a practice round with the timer off, so the first try is not discouraging.
• Track progress simply. Write the date and score on the printed sheet and keep them in one folder.
• Mix skills. Follow a drill with a calmer activity such as number order or comparing numbers so the session ends gently.
• Classroom use: run a one minute drill at the start of the maths period as a daily routine. Children settle quickly and start thinking about numbers straight away.

Why timed practice works

When a child knows that 7 + 5 is 12 without stopping to count, word problems, multiplication and later topics become much easier. The purpose of the timer is not pressure but rhythm: it makes practice feel like a small game with a clear finish. Because every attempt gives fresh sums, children can return day after day, and because every activity is free and printable, families and schools can use it as often as they like.
