It’s one of the most confusing moments for a parent: your child can recite their times tables confidently at home, yet comes back from a timed test or the Multiplication Tables Check with a lower score than expected. It isn’t laziness, and it isn’t that they “forgot.” It’s usually a gap between two very different skills — knowing an answer, and recalling it instantly under pressure.
Why Knowing Isn’t the Same as Fluency
There are, broadly, three different ways a child can arrive at “7 × 6 = 42”:
- Working it out. Counting up in 6s, using repeated addition, or doubling and adjusting. This works, but it takes several seconds and uses up working memory.
- Recognising it. The child has seen the fact often enough that it feels familiar, and with a moment’s thought, the answer comes.
- Instant recall. The answer appears in under a second or two, with no visible calculation at all — the fact is simply known, the same way most adults know 2 + 2 = 4.
Only the third stage counts as true fluency, and it’s the only one fast enough to survive a strict time limit like the MTC’s 6 seconds per question. A child can be entirely accurate at home, where there’s no clock and no pressure, while still sitting in stage one or two for a meaningful number of facts.
Key Challenges Behind the Gap
- Untimed practice masks the problem. Worksheets and verbal quizzing at home rarely have a strict timer, so a child who takes four or five seconds to work something out still gets marked “correct” — even though that’s too slow for a real timed test.
- Order dependency. Many children learn tables in sequence (1×, 2×, 3× and so on) and become fast at reciting them in that order, but slow down noticeably when facts are asked randomly, exactly as they are in the MTC.
- Working memory load under pressure. Timers and test conditions add a layer of stress that can slow down recall even for facts a child normally knows well — this is a real, well-documented effect, not a sign of poor preparation.
- Uneven fluency across tables. A child might have true instant recall for the 2, 5 and 10 times tables, but still be “working it out” for 6, 7, 8 and 9 — dragging down their overall timed performance even though most of their knowledge is solid.
Practical Solutions That Close the Gap
The fix isn’t more repetition of the same untimed practice — it’s practice that specifically targets speed under realistic conditions:
- Introduce a timer early. Once a table is “known,” start timing responses, even informally, so slow recall becomes visible rather than hidden behind an eventually-correct answer.
- Practise out of order. Randomise which fact is asked next, rather than always working through a table from the beginning — this trains the actual retrieval skill the MTC tests.
- Separate “known” from “fast.” Keep a simple mental note (or use an app that tracks it automatically) of which facts are answered instantly versus which ones still take a pause — and give the slower ones extra focused practice.
- Build speed gradually. Don’t jump straight to strict 6-second pressure. Start with a slightly longer window and tighten it over a few weeks as genuine fluency develops.
- Keep sessions short but frequent. Fluency is built by frequent retrieval practice over time, not by long single sessions — five minutes daily beats thirty minutes once a week.
How RoarMath Can Help
This exact accuracy-versus-speed gap is the reason RoarMath times every single answer to the tenth of a second, rather than simply marking questions right or wrong. A fact only counts as truly fluent once it’s answered both correctly and quickly — which means the app can tell the difference between a child who has genuinely mastered a fact and one who is still quietly working it out under the surface.
Facts that are correct but slow are exactly what RoarMath’s shaky-fact radar is designed to catch, feeding them back into future sessions via Tiger’s Den until they become instant. Meanwhile, RoarMath’s rank system — from Sapling up to Jungle King — is based purely on average seconds per correct answer, so a child’s progress is measured on the skill that actually matters for timed tests, not just on whether they eventually get answers right.
Conclusion
A child who “knows” their times tables but underperforms on a timed check almost always has a speed problem, not a knowledge problem — and speed is trainable, with the right kind of practice. Timed, randomised, frequent retrieval closes this gap far faster than more of the same untimed drilling.
