Fraction Addition & Subtraction
Practice fraction addition and subtraction with a free, browser-based math game. Includes step-by-step strategy, common mistakes, and classroom tips.
MathA free, in-browser game that turns division from a memorised table into something you can do under pressure. Below: how it works and the checks that catch most wrong answers.
Pick a level to start playing. You can switch at any time.
Work out the quotient, then tap the correct answer. Every problem divides exactly, so there is never a remainder to round.

MathTurn a number written in place-value parts back into digits, in a free timed browser game. 3,000 + 400 + 70 + 5 is 3,475.
MathFind the remainder after division in a free, timed browser game. The number left over can never reach the divisor.
MathDecide which of two fractions is larger in a free, timed browser game. Cross-multiply instead of converting.
MathType the answer instead of choosing it, in a free timed browser game. No options to guess between — just the arithmetic.
MathDivision is the inverse of multiplication, and that sentence is the whole strategy. When the game shows 56 ÷ 7, the fastest route to an answer is not long division: it is asking 7 × ? = 56. Players who have internalised their times tables answer in under two seconds. Players who have not end up counting up in sevens, which is slow and error-prone under a timer.
Every problem in this game divides exactly. There is never a remainder, and never a decimal to round. That is deliberate: it keeps the task focused on recalling a fact rather than on the mechanics of long division, which is a separate skill worth practising separately.
One problem at a time, four choices, a countdown. A correct answer scores points and moves on; a wrong answer reveals the correct one so the fact still lands. Your score and your best score stay in this browser only, so nothing leaves your device.
Difficulty changes the size of the numbers, not the kind of thinking. Easy keeps divisors to 2 through 5; Medium goes to 9; Hard goes to 12 with larger quotients. Pick a level on the start screen and switch at any time from the row above the problem.
Multiply back. However you reached a quotient, multiply it by the divisor. If you do not get the dividend, the answer is wrong. This takes one second and catches nearly every slip.
Estimate the size first. 96 ÷ 4 must be in the twenties, because 4 × 20 = 80 and 4 × 30 = 120. If your answer is 12 or 240, the place value has moved.
Watch the swap trap. 56 ÷ 7 and 56 ÷ 8 look similar at a glance. Read the divisor, not the dividend, before you commit.
Mistake: answering with the divisor instead of the quotient. Under time pressure, players sometimes tap the number they just read. The fix is to say the question as how many times does 7 go into 56 before tapping.
Mistake: off-by-one from a shaky times table. 7 × 8 = 56, not 54. The fix is drilling the tables that feel slow rather than the ones that already feel easy.
Mistake: losing a zero on large dividends. 120 ÷ 4 = 30, not 3. The fix is the multiply-back check, which fails instantly if a zero is missing.
Two or three minutes as a warm-up works better than a long drill. Ask students to say the multiplication check out loud: 8 times 7 is 56 is both the answer and the proof. Because scores are stored locally, a class set of tablets will not collide, and students can retry without an account.
Do I need to install anything? No. It runs in any modern browser and needs no download.
Why are there no remainders? Because the goal here is fact recall. Long division with remainders is a different skill and belongs in a different drill.
What age is it for? Roughly grades 3 through 6, or any adult rebuilding arithmetic speed.
