1. The Enduring Appeal of Manipulatives in Education

For decades, educators have championed manipulatives as a means to make abstract concepts more accessible to students. These concrete objects, ranging from colorful blocks to everyday items, are believed to bridge the gap between theoretical knowledge and real-world application. The National Association for the Education of Young Children and the National Council of Teachers of Mathematics advocate for using a wide array of materials in math-rich classrooms. Teachers seem to agree, frequently incorporating manipulatives into their lessons. But why do manipulatives hold such enduring appeal, and what does the research say about their effectiveness?

2. Debunking Myths: Why Manipulatives Aren’t Just for Concrete Thinkers

2.1. Challenging Piaget’s Theory of Cognitive Development

Initially, the popularity of manipulatives stemmed from theories suggesting that young children are primarily concrete thinkers. Influential figures like Jerome Bruner and Jean Piaget proposed that children’s cognitive development progresses from concrete to abstract thinking. According to this view, manipulatives provide the necessary physical interaction for young learners to grasp concepts they couldn’t otherwise understand. Piaget’s theory posits that in the concrete operational stage (ages 7-12), children rely on concrete objects for logical reasoning. Only later, in the formal operations stage (age 12 to adulthood), can they engage in pure abstraction. However, modern research challenges this notion.

2.2. Abstract Thinking in Early Childhood

Contrary to Piaget’s assertions, research demonstrates that even preschoolers exhibit abstract thinking. Studies on children’s understanding of numbers reveal that while they may make counting errors, their counting methods demonstrate an understanding of the underlying principles. They understand that each item gets one number tag, the tags are used in a consistent order, and the final tag represents the total number of items. Furthermore, preschoolers show abstract thought in areas like understanding categories such as “living things”. Therefore, the idea that children’s thinking is strictly tied to concrete objects is inaccurate.

2.3. Beyond Kinesthetic Learning: It’s Not Just About Movement

Another theory suggests that manipulatives are effective because they involve physical movement. Some researchers believe that cognition isn’t solely a mental process but also involves bodily participation. This perspective suggests that mental representations may be rooted in perception or action. For example, thinking about “blue” might depend on the same mental representation used when perceiving blue. By this account, manipulatives would be effective because their demand for movement aligns with how thought is represented.

However, research comparing physical and virtual manipulatives challenges this theory. While some studies show exceptions, virtual manipulatives often prove just as effective as their physical counterparts. This suggests that movement isn’t the primary driver of manipulatives’ effectiveness. Both theories – children as concrete thinkers and physical movement as central to thought – incorrectly imply that manipulatives always lead to better understanding.

3. The Analogy Theory: How Manipulatives Facilitate Understanding

3.1. Manipulatives as Analogies and Symbols

A more robust theory proposes that manipulatives function as analogies, serving as symbols for new concepts. This perspective views manipulatives not as readily understood objects in themselves, but as representations of more complex ideas. For instance, popsicle sticks can represent the abstract concept of number, making it easier for children to grasp. This theory aligns with the widespread use of manipulatives in math and science, fields abundant with unintuitive concepts like place value and velocity.

3.2. Connecting the Known to the Unknown

Analogies aid understanding by drawing parallels between new and familiar concepts. Children might have prior experience with fractions in the context of sharing a pizza, even if they lack the formal vocabulary. Manipulatives can then leverage this existing knowledge, using the familiar idea of pizza to illustrate the abstract concept of fractions. This theory explains why embedding problems in familiar scenarios helps students, even without physical manipulation.

3.3. Evidence Supporting the Analogy Theory

One study compared students solving algebra problems in symbolic form versus when embedded in a familiar scenario. Students who read a problem about buying donuts were more successful than those who saw the same problem presented purely symbolically. This supports the idea that manipulatives, like familiar scenarios, act as analogies that make abstract concepts more accessible. By understanding manipulatives as analogies, educators can better understand when and how they are most effective.

4. The Critical Role of Attention in Manipulative-Based Learning

4.1. Directing Attention to Relevant Features

For manipulatives to be effective, students must pay attention to them, and research has explored the impact of perceptual richness (e.g., color, visual complexity) in attracting attention. One study examining fifth-graders solving math word problems involving money found that those using perceptually rich play money made fewer conceptual errors (setting up the math correctly) compared to those using bland paper money. Another study involving 3- to 4-year-olds learning numerical concepts found that realistic-looking frog counters were more effective than simple green counters.

4.2. Guided Instruction and Focused Attention

However, perceptual richness isn’t the only factor. The study with the 3- to 4-year-olds also investigated the role of instruction. When the experimenter modeled how to play the game and provided feedback, children using bland counters learned as much as those using perceptually rich counters. This highlights the importance of instruction in guiding attention effectively. In some cases, simply instructing students on how to use the manipulative can focus their attention on the relevant feature.

4.3. Effective Strategies for Guiding Attention

Consider using a numbered line to teach addition. Instead of counting “1, 2, 3” from the starting number, a more effective method is to count “7, 8, 9” after identifying the initial number. Researchers tested this approach with kindergartners playing a game similar to Chutes and Ladders, finding that those who counted from the initial number showed greater gains in number understanding. Jerome Bruner emphasized the importance of teacher guidance, suggesting that students are unlikely to learn target concepts through unstructured exploration. While excessive control can backfire, some guidance is essential.

5. When Manipulatives Fall Short: Irrelevant Features and Cognitive Overload

5.1. Poorly Designed Manipulatives

While perceptually rich manipulatives can be engaging, they aren’t always the best choice. Manipulatives are analogies, and like all analogies, they are imperfect. They are most effective when they highlight the key feature relevant to the concept being taught. Manipulatives can fail when children focus on irrelevant features. This can happen in several ways. First, the manipulative might be poorly designed, lacking the crucial feature. For example, board games with numbers arranged linearly help children understand number properties because they are analogous to the number line. However, if the numbers are arranged in a circle, the benefit disappears.

5.2. Distracting Features and Perceptual Overload

Second, the manipulative might have the relevant feature, but the child doesn’t attend to it because another feature is more salient. This is where perceptual richness can backfire. Imagine Cuisenaire rods (designed to teach number concepts) painted to resemble superhero action figures. Students would likely focus on the superhero aspect rather than the rods’ differing lengths, which are the key symbolic feature. Even less obvious distractions can confuse children. The child has no inherent way of knowing which features of the manipulative are important.

5.3. The Challenge of Symbolic Representation

Furthermore, even if the child knows which feature is relevant, they might struggle to remember that it is a symbol. For example, in the play money experiment, the children were already familiar with real money, and the play money was meant to serve the same purpose. However, more often, the symbolic connection is new. A child is used to thinking of a slice of pie as something to eat, but now it’s supposed to represent the abstract idea of “⅛ of a whole.” Research shows that this duality poses a problem, potentially overwhelming working memory in young children.

6. Bridging the Gap: From Manipulatives to Abstract Understanding

6.1. The Goal: Independence from Manipulatives

The ultimate goal is to help students move beyond reliance on manipulatives. We don’t expect high school students to use beads to solve math problems. Manipulatives can be time-consuming and may not apply to all situations. For example, using a pizza to illustrate fractions works well until you encounter a fraction with a denominator of 9 or 10,000. Similarly, using colored chips to represent positive and negative numbers might not easily represent all problems.

6.2. The Challenge of Transfer

The expectation is that manipulatives will foster conceptual understanding that students can then transfer to symbolic representation. However, it’s not always that simple. As we’ve seen, perceptually rich manipulatives can draw attention to themselves, potentially highlighting the wrong properties. One study showed that while realistic-looking ants in a computer simulation helped undergraduates learn a principle of self-organization more quickly, transfer to conceptually similar problems was worse than with simple dots.

6.3. Abstract Symbols and Generalization

Other research confirms that generalization can be better with abstract symbols. Undergraduates taught a new math concept using geometric shapes showed better transfer to different problems than those taught using familiar symbols (cups of water). Even when students learn a concept with manipulatives and written symbols simultaneously, the two may remain separate. A yearlong study of third-graders using Dienes blocks found that those most proficient with the blocks were actually the worst at solving the same problems with standard written notation.

7. Best Practices for Using Manipulatives Effectively in the Classroom

7.1. Key Considerations for Effective Manipulative Use

Based on research, here are key considerations for using manipulatives effectively in the classroom:

• Temper Enthusiasm: Recognize that manipulatives aren’t always beneficial and can sometimes hinder learning.
• Focus on Relevant Features: Choose objects that highlight the specific feature conveying information (e.g., the length of a rod representing number).
• Provide Guided Instruction: Offer instruction that makes the relevant feature salient, but avoid being so controlling that students don’t think for themselves.
• Explicit Connections: Make the parallel between the manipulative and the concept explicit.

7.2. Concreteness Fading: A Gradual Transition

Two additional ideas with less direct empirical support are worth considering. The first is concreteness fading, originally proposed by Bruner. This approach involves starting with concrete, perceptually rich manipulatives and gradually moving to more abstract symbols. The Singapore math method is an example, using stuffed animals, then stickers, and finally plain blocks. While intuitively appealing, more research is needed to confirm its utility.

7.3. Consistency and Memory Load

The second idea is the consistent use of the same set of manipulatives for the same concept. While it’s tempting to use different items for variety, thinking of manipulatives as analogies suggests comprehension will be better with consistency. Concreteness fading can be used to establish a connection between a manipulative and a concept, and then that manipulative is used consistently. This reduces the memory load for students, allowing them to benefit from their previous work.
