A word problem asks for two skills at once: reading and interpreting language, then applying the right maths. Struggling with one can look exactly like struggling with the other.

It's a genuinely common and confusing pattern: a child who can calculate confidently on a bare arithmetic worksheet falls apart the moment the same calculation is wrapped in a sentence. That gap between "can do the maths" and "can do the word problem" is worth understanding properly, because the fix depends entirely on which one is actually the issue.
A word problem asks a child to do something a bare calculation never requires: translate ordinary language into a mathematical structure, decide which operation applies, and only then calculate. That translation step is doing real cognitive work of its own, separate from the arithmetic that follows it — which means a child can be entirely secure on the maths and still get the question wrong, purely because the translation went astray.
Many children are taught, informally or explicitly, to spot certain words and match them to operations — "altogether" means add, "left" means subtract, "each" means divide. This works often enough to feel reliable, which is exactly the problem: the first time a question uses "altogether" in a context that actually needs multiplication, or "left" in a context that needs addition, keyword-spotting produces a confident, wrong answer. The strategy fails silently, without the child realising anything went wrong.
A child with weaker reading fluency can genuinely struggle to construct the situation the problem describes, independent of their maths ability — they may understand every individual word but struggle to hold the whole scenario in mind while extracting the relevant numbers. Reading the same question aloud, or breaking it into shorter sentences, sometimes reveals a child who can solve the maths perfectly well once the reading load is reduced.
The reverse also happens: a child with strong reading and general comprehension can sometimes talk their way to a plausible-sounding answer without the underlying maths being secure, because the context does some of the reasoning work for them. Both directions are worth being aware of before assuming a wrong answer on a word problem is purely a maths issue.
Even once the right operation is identified, many word problems need more than one step — find an intermediate value first, then use that to answer the actual question. Losing track of which number is the final answer, versus a stepping stone along the way, is a very common source of error that has nothing to do with whether either individual calculation was done correctly.
A useful diagnostic: give the same numbers as a bare calculation first, then as a word problem. If the bare calculation is fine but the word problem isn't, the gap is in the translation step, not the maths — and that needs a different kind of practice, which we cover in how to teach maths word problems step by step.
Grasp Maths tracks calculation fluency and worded problem-solving as genuinely separate skills, so a gap in one doesn't get mistaken for a gap in the other — and practice targets whichever one is actually holding a child back.
