Should teachers use manipulatives when teaching math? What is the purpose of manipulatives? Are some manipulatives better than others? Every mathematics teacher should ask these questions as consider how to effectively teach their students. Let’s start by considering:

*What is a manipulative? *

A manipulative is a tangible object a child can physically handle to learn math. Some curricula do not encourage concrete manipulatives at all. Other curricula only use physical manipulatives as a last resort or when the child has learning difficulties. However, other programs, like RightStart Math, use concrete manipulatives as a tool for understanding.

*What makes an excellent manipulative?*

An excellent physical manipulative is one the child can imagine, internalize, visualize, and use in their mind. RightStart Math uses specific manipulatives to ensure students can visualize and internalize the math concepts they are being taught.

A few of the excellent manipulatives used throughout the RightStart Math curriculum are the Cotter Abacus, overlapping place value cards, fraction charts, base-10 picture cards, and centimeter cubes.

**How long should my students use manipulatives?**

According to research, it takes a child one year of regularly using the manipulative to gain the full benefit of it. Many teachers use a manipulative to demonstrate a concept but do not allow enough time for students to explore, discover, and apply mathematical ideas. Remember, a good manipulative can be internalized. It takes time for a student to visualize the concepts a manipulative conveys.

*Aren’t all math materials considered manipulatives?*

*Aren’t all math materials considered manipulatives?*

Many believe that math materials such as rulers, geoboards, calculators, goniometers, clocks, and coins are manipulatives. But really, they are math tools and applications of math, not manipulatives.

*How important are manipulatives, anyway?*

*How important are manipulatives, anyway?*

Researchers have found there are two vital outcomes when children use manipulatives:

- They learn and understand mathematics better
- They have a positive attitude toward math

These two outcomes occur when manipulatives are used ** while **teaching a mathematical idea, not as a reward for completing a project or assignment. When concrete materials and games are considered rewards for good behavior, the student views the manipulative as nonessential and is less likely to take it seriously.

However, simply using a manipulative does not guarantee the student understands a math concept. Ben A. Sueltz stated,

Devices themselves will teach very little arithmetic.

It is the guidance of a good teacher that determines their usefulness

in discovery and learning.

*Can I use everyday objects as manipulatives?*

*Can I use everyday objects as manipulatives?*

Some professionals suggest that objects commonly found within the home are good alternatives to math manipulatives because they make math seem more relevant. While this might be true for some math concepts, everyday items do not necessarily make a good math manipulative. In fact, the more interesting the object is in its own right, the harder it is for the child to see the intended mathematical idea it is trying to demonstrate.

For example, students who use raisins and candies to view and manipulate quantities can find the treats too tempting, and their attention is pulled away from the math concept.

*Summary*

*Summary*

Teachers and schools can choose from a wide array of manipulatives to use in their math classrooms. Each year, new manipulatives are being developed. However, teachers should be selective and intentional to only incorporate good manipulatives in their instruction. The manipulatives they choose should help students understand abstract concepts, make mathematical connections, and enjoy learning math.
