Mental maths, or the capacity to execute arithmetic without utilising paper, pencil, or a calculator, is more than just an academic skill. It provides insight into a child's cognitive development and is an effective technique for improving brain function. Researchers and educators have both acknowledged the substantial link between mental maths and the development of critical cognitive capacities such as working memory, attention, processing speed, and problem-solving.
This article delves into the science of mental maths and its impact on children's cognitive development, drawing on research findings.
Working memory is the brain's ability to briefly store and manipulate information. It is essential for reasoning, learning, and understanding. Mental maths relies largely on working memory since children must remember several numbers and procedures at the same time.
To mentally calculate 47 + 36, a youngster could first add 40 + 30 = 70, then 7 + 6 = 13, and finally put them together (70 + 13 = 83). This process necessitates the dynamic storage and update of information in the brain.
According to cognitive science research, children who engage in mental math exercises on a regular basis improve their working memory capacity dramatically over time. Mental maths can help improve reading comprehension and overall academic achievement.
Processing speed describes how quickly a person can do simple or automated cognitive tasks. In the framework of mental math, children learn to recognise number patterns, recall arithmetic knowledge, and perform operations fast.
When children practise mental maths on a regular basis, they improve their ability to recognise mathematical relationships and patterns, which increases their overall processing speed.
Neuroimaging studies demonstrate that consistent practice strengthens neuronal connections in areas responsible for number cognition, particularly the parietal lobes. This allows for speedier information retrieval and task execution.
Number sense is an intuitive awareness of numbers, their quantity, relationships, and the effects of operations. Mental maths improves number sense by encouraging flexible thinking over rote memorisation.
Children with strong numerical abilities can estimate, reason, and solve issues more successfully. They understand why a solution works, not just how to achieve it.
Instead of memorising that 9 + 6 = 15, a child may think, "9 + 1 = 10, and 6 is one more than 5, so 10 + 5 = 15." This breakdown demonstrates logical reasoning rather than simple recall.
To solve mental math problems, you must focus your concentration and disregard distractions. As a result, consistent mental arithmetic exercise helps youngsters concentrate for longer periods of time.
Mental math tasks activate the prefrontal cortex, which is responsible for executive functions like attention control, planning, and decision-making.
Children who excel at mental maths are also better able to focus on other academic tasks and manage classroom instructions.
Mental maths encourages logical reasoning because it frequently forces the child to select the most effective technique for solving a problem. It's not just about getting the answer but also determining the best path to get there.
A child may find 99 × 7 challenging, but by recognising that 99 = 100 - 1, they can compute (100 × 7) - (1 × 7) = 700 - 7 = 693 using logic and pattern recognition.
This type of logical manipulation of numbers extends to science, technology, and problem solving in everyday life.
Mental math exercises promote neuroplasticity, or the brain's ability to reorganise itself by generating new neural connections. When children participate in mentally taxing activities such as mental maths, their brains adapt and grow more efficient over time.
Functional MRI scans reveal increased activity and connectivity in brain regions such as the intraparietal sulcus and dorsolateral prefrontal cortex during mental arithmetic, indicating long-term cognitive improvement.
Successful mental math performance boosts a child's confidence in their abilities, resulting in less math anxiety and increased academic engagement.
When children realise they can solve problems mentally, they feel more competent and resilient, not just in maths but across all subjects.
Mental maths teaches youngsters how to control cognitive load, which is the amount of information they can process at once without becoming overwhelmed. Efficient strategies demand less mental effort, making difficult activities more manageable.
Techniques such as "chunking" (dividing numbers into smaller parts) and rounding and compensation strategies help to reduce the strain on working memory.
The science of mental maths is strongly entrenched in cognitive development. It's not only about making numbers faster; it's also about improving the brain's ability to think, comprehend, and solve problems. Mental maths provides a thorough workout for the developing mind, enhancing working memory and processing speed while also sharpening attention and logical thinking.
Incorporating mental math tasks in early childhood can set the stage for a lifetime of cognitive benefits. Encouraging mental arithmetic through games, real-world problem-solving, and daily practice not only promotes academic advancement but also fosters a child's whole cognitive and emotional development.
