Think of it like learning to ride a bike. To get good at it, you have to do it all the time. Nowadays, most money is "invisible." Young people see their parents tap a phone or a card against a machine to pay for things. Since they rarely see or touch actual paper bills and metal coins, they don't get the daily practice needed to get comfortable with them. Coins can also be pretty confusing because their size doesn't always match how much they are worth. For example, a tiny dime is worth more than a bigger nickel. If you don't use them every day, it’s hard to remember those "rules." It’s like trying to play a board game where the smallest pieces are actually the most powerful; if you only play once a year, you’re going to forget how it works. Finally, we have technology that does the math for us. Cash registers tell the clerk exactly how much change to give back, so nobody has to do the "take away" math in their head anymore. Because they don't have to use that "math muscle" very often, it stays a bit weak. It’s not that they can't learn it; they just haven't had many reasons to practice it in the real world.

Struggles with currency often stem from underlying neurodivergent profiles, such as dyscalculia or executive functioning challenges. For many young people, the issue isn't a lack of effort but rather a difficulty with "number sense"—the intuitive ability to understand that a small dime holds more value than a larger nickel. When a student has trouble with working memory, holding multiple values in their head while simultaneously performing subtraction for change can lead to cognitive overload and significant frustration. We must also consider how abstract the concept of money can be. It requires the simultaneous processing of visual recognition, mental arithmetic, and multi-step sequencing. If a learner has a processing speed delay or a specific learning disability in mathematics, the rapid-fire nature of a cash transaction becomes a major barrier. These students aren't "bad at math"; their brains are simply navigating a complex set of symbols and values that do not always align with physical size or quantity. To support these learners, I recommend tailored interventions that move from the concrete to the abstract. Using multisensory tools, such as "touch-points" on coins or visual "cheat sheets" for common denominations, can bridge the gap. By breaking the process down into manageable steps and providing a low-pressure environment for scaffolded practice, we can help students build the confidence and compensatory strategies they need to navigate financial literacy successfully.

Learning to count money is a big jump for children because coins are quite abstract. For a young learner, it’s confusing that a tiny silver dime is worth more than a larger, thicker nickel. In most of our early math lessons, we teach that "more" usually means physically bigger or taller. Memorizing these arbitrary values takes a lot of hands-on practice with real, tactile coins before the logic truly clicks. We also have to consider that many students don't see physical cash used in their daily lives as much as previous generations did. When parents pay with a quick tap of a card or a phone, children miss out on the "concrete" experience of watching money being exchanged and counted. Without seeing those real-world transactions regularly, the concept of "making change" feels like a theoretical puzzle rather than a practical life skill. Finally, making change requires a sophisticated skill called "counting on." It’s much more complex than simple addition because you have to start at the price and count up to the amount paid using different denominations. It takes a lot of patience and foundational work with number lines to help students feel confident navigating those jumps between pennies, nickels, and quarters.

Educational Psychologist

From a cognitive perspective, counting money and making change are not simple arithmetic tasks; they require the integration of symbolic representation, working memory, and mental manipulation. Learners must map abstract numerical values onto physical objects that often lack proportional logic—for instance, a dime is physically smaller than a nickel but holds double the value. This requires a high level of executive function to suppress the visual cue of size in favor of the abstract value, a process that can be taxing for those whose cognitive schemas for number sense are not yet fully automated. Environmental factors have further complicated this developmental milestone. The transition to a cashless society has significantly reduced "deliberate practice" opportunities. When transactions are digital, the concrete relationship between the exchange of goods and the subtraction of physical resources is severed. Without frequent, real-world reinforcement, the neural pathways required for "counting up" to make change—a more efficient cognitive strategy than standard subtraction—fail to solidify, leading to a reliance on calculators and a lack of intuitive fluency. Finally, individual differences in neurodevelopment, such as dyscalculia or deficits in working memory, can create significant bottlenecks. Making change is a multi-step procedure that involves holding a starting total in mind while simultaneously performing iterative addition. For a student with limited working memory capacity, the cognitive load of the task exceeds their processing threshold. To optimize learning outcomes, evidence-based interventions must utilize concrete-representational-abstract (CRA) sequences, gradually fading support as the learner builds the requisite mental models.

From a cognitive perspective, the primary challenge lies in the non-proportional nature of currency. Unlike base-ten manipulatives where physical size corresponds to value, coins are symbolic. A dime is physically smaller than a nickel but holds double the value, requiring learners to inhibit perceptual biases in favor of abstract retrieval. For students with underdeveloped working memory or weak number sense, the cognitive load of simultaneously identifying denominations and performing multi-step mental arithmetic—such as "counting on" to reach a total—often leads to procedural breakdown. Environmental factors further exacerbate these difficulties. In an increasingly digital economy, young people have fewer opportunities for incidental learning through physical transactions. Research indicates that a lack of contextualized practice prevents the development of "money sense," leaving the relationship between denominations as an abstract concept rather than a concrete reality. Effective intervention must bridge this gap using the Concrete-Representational-Abstract (CRA) instructional sequence, ensuring students master the physical manipulation of coins before moving to mental computation. Furthermore, making change requires sophisticated decomposition skills and the ability to perform "subtraction by addition." Many students struggle because they are taught rigid algorithms rather than flexible strategies like the "shopkeeper’s method." Evidence-based instruction emphasizes teaching students to count up from the purchase price to the amount tendered. By focusing on these relational strategies rather than rote memorization, educators can help students build the cognitive flexibility necessary for real-world financial literacy.
