About Four Operations Mixed Review
Practising one operation at a time builds speed; mixing them builds the thing that actually gets tested, which is noticing which operation a question needs before starting it. Pupils who are fluent in isolation often slow right down on a mixed page, and that gap is what this worksheet is for. The grid holds twelve calculations laid out in a bordered table with an answer space beside each, and the four operations are dealt in equal numbers and then shuffled rather than drawn at random — a genuinely random mix routinely comes out half multiplication, which defeats the purpose. Every division is built from its quotient, so all of them are exact and none divides by zero. Subtractions are ordered to stay positive, since negative results belong on the integers worksheet rather than a fluency page. Number sizes grow across the five levels while the balance of operations stays fixed, so what changes is the arithmetic rather than the mix. The answer key follows the grid order exactly, left to right and top to bottom, so marking is a straight read-down. Each level prints as a clean A4 sheet in black and white with its own separate answer key.
Common questions
- Is the mix of operations really balanced?
- Yes. The four operations are dealt in equal numbers and then shuffled, rather than drawn at random.
- Are the divisions exact?
- Yes. Every division is built from its quotient, so none leaves a remainder and none divides by zero.
- Can an answer be negative?
- No. Subtractions are ordered to stay positive; negative results belong on the integers worksheet.
- Does the answer key follow the grid order?
- Yes, exactly — left to right and top to bottom, so marking is a straight read-down.
A hand for grown-ups
- Before you start
- Have something countable nearby. Being able to check "3 and 2 really is 5" by counting builds trust in the maths.
- While they work
- If a sum is hard, suggest counting on from the bigger number rather than counting both from one. It is a real strategy, not a crutch.
- Afterwards
- Try one together out loud, talking through how you worked it out. Hearing an adult think aloud is genuinely useful.
- Watch out for
- Counting both numbers from one every time. Nudge gently towards "start at the bigger one and count on".
- Away from the screen
- Add up small shopping items, or dots on two dice. Board games with dice are addition practice in disguise.
