A Surprising Discovery About How Kids Learn Maths
If you've ever wondered why some children seem to pick up maths concepts easily while others struggle, researchers at PLOS ONE have uncovered something important: your child's ability to remember and recall information plays a much bigger role than previously thought.
A longitudinal study tracking children over time found that declarative memory—the capacity to remember facts, figures, and information—is a strong foundation for maths success. This isn't about rote memorisation for its own sake. Rather, children who can reliably store and retrieve basic maths facts (like times tables or number bonds) free up mental space to tackle more complex problem-solving. It's like having the building blocks firmly in place before constructing the house.
What This Means for Singapore Families
For parents in Singapore and across Asia, where academic achievement is often tied to future opportunities, this research offers reassuring news. It means that supporting your child's maths journey isn't just about hiring a tutor or pushing harder on problem sets. It's also about strengthening their fundamental memory skills.
Singapore's curriculum already emphasises conceptual understanding alongside procedural fluency, which aligns well with this research. However, many parents unknowingly focus exclusively on 'understanding' without recognising that solid memory foundations make understanding stick better. Children who can automatically recall that 7 × 8 = 56 don't have to use up working memory on basic facts—they can direct their mental energy towards reasoning about why multiplication works or how to apply it to real problems.
This is particularly relevant in our fast-paced education system, where children are expected to build increasingly complex skills year on year. Starting with strong declarative memory gives them the scaffolding they need to progress confidently.
Three Practical Ways to Support Your Child's Memory Skills
- Make repetition meaningful, not tedious. Instead of endless flashcard drills, weave maths facts into daily life. Ask 'How many days until your birthday?' during meal prep, play number games during car rides, or use board games that require quick mental maths. When children see facts used in context, they remember them better and don't resent the practice.
- Space out learning over time. Rather than cramming maths facts in one sitting, revisit them regularly across weeks and months. A few minutes of maths talk three times a week beats an hour-long session once a week. This spaced repetition is how long-term memory gets built, and it's far less stressful for both parent and child.
- Celebrate memory milestones alongside problem-solving wins. When your child automatically knows their times tables or recalls a maths strategy without prompting, acknowledge it. This reinforces that memory skills are valuable and worth developing, not just a stepping stone to 'real' maths.
The bottom line? Your child's ability to remember and retrieve maths facts isn't a limitation—it's a superpower that sets them up for success. By building strong declarative memory skills early, you're giving them the confidence and cognitive space to become flexible, creative mathematicians.
