Mental math gets easier when practice is short enough to repeat. Ten focused minutes can be more useful than a long session you keep postponing.
Start easy for two minutes
Begin with calculations you can usually solve without hesitation: 27 + 18, 46 + 35, or 125 + 70. The point is to settle into the numbers, not to race.
Spend three minutes on one weak area
Pick one operation. If subtraction slows you down, try questions such as 82 − 47 and 150 − 68. On another day, work on multiplication by 6, 7, 8 or 9.
Mix the questions for three minutes
Switch between operations. This forces you to notice the sign and choose a method before calculating. Accuracy comes first; speed tends to follow once the method feels familiar.
Use the final two minutes to review
Look at the questions that took longest. Was the arithmetic difficult, or did you choose an awkward route? For example, 49 + 36 becomes easier when you think 50 + 36 − 1.
Keep a tiny note
Write the date, what you practised and one thing that felt difficult. After a week, you will have a much clearer idea of what actually needs attention.

Quick Math can be the mixed part of the routine. Play a few levels, notice where you hesitate, then practise that type separately. Scores are useful as feedback, not as a judgment of ability.
Consistency matters more than making every session difficult. A small routine you actually repeat is the better routine.
A simple practice log you can keep
Monday: if you missed 72 − 38, write down the route you took. One reliable path is 72 − 40 + 2 = 34. Tuesday: repeat the same kind of subtraction with 91 − 47, then compare how long the method took you. A record like “I forgot to adjust after rounding” is more helpful than “I was bad at subtraction.”
Try 58 + 27 without paper. One route is 58 + 20 = 78, then 78 + 7 = 85. A second route is 60 + 27 − 2 = 85. Neither route is compulsory; choose the one you can verify confidently.
Three questions that tell you where to practise next
Try these without a calculator: 76 + 19, 105 − 58 and 14 × 6. Don't measure your time yet. Notice which problem makes you change methods halfway through. For the addition, 76 + 20 − 1 = 95. For the subtraction, count from 58 up to 100 (42), then add 5, giving 47. For multiplication, 10 × 6 + 4 × 6 = 84. Different routes are fine, provided you understand how you got there.
A useful review is more specific than “I was too slow”. Perhaps you forgot the −1 after rounding 19 to 20. Perhaps the subtraction became confusing when you tried to borrow. Those observations point to two distinct practice sessions. On a later day, change the numbers but keep the same type of calculation. This tests the method, not your memory of a previous answer.
When the routine becomes too easy
Increase one thing at a time. Move from two-digit addition to three-digit addition, or mix subtraction into an addition set. Resist making the timer shorter and the questions harder on the same day: if accuracy falls, you won't know what caused it. For a timed round in Quick Math, choose a comfortable rhythm first. The game is a place to apply the method; it doesn't have to dictate every minute of your practice.
