![]() ![]() There is some amount of effort on the part of the student to extract the mathematical ideas from interacting with physical manipulatives (like blocks). What are the differences between physical and virtual manipulatives? Although virtual manipulatives have some similarities with their physical manipulative counterparts, as cognitive tools virtual manipulatives have unique characteristics that go beyond the capabilities of physical manipulatives. Virtual manipulatives give learners the same opportunity to make meaning and see relationships as the result of their actions, just like a physical manipulative. Virtual manipulatives are cognitive technological tools that are a dynamic visual representation of physical manipulatives which can be operated through a computer mouse (or a finger on a tablet) to slide, flip, and turn just like a three-dimensional object. It’s important for children to have a variety of materials to manipulate and the opportunity to sort, classify, weigh, stack, and explore to help them construct their own mathematical thinking and knowledge with Cuisenaire Rods, Base 10 Blocks, and Fraction Circles. Physical, or concrete, manipulatives are physical objects that are used as teaching tools to engage students in the hands-on learning of mathematics to introduce math concepts. How are physical and virtual manipulatives defined? With online virtual manipulatives readily available to bring math concepts to life, are they ‘better’ than physical manipulatives? Manipulatives can make an enormous contribution to sense-making abilities for all students-and have been shown to be of special benefit to students who are high-risk, learning disabled, or with limited English proficiency to understand the symbolic language of math. ![]() The essential abstract concepts can be difficult for some students, especially younger learners. ![]() I do and I remember.” There is wisdom in the proverb, because educational research suggests that the most valuable learning happens when students actively construct their own mathematical understanding. Why do we need manipulatives to teach math?Īn ancient Chinese proverb says, “I hear and I forget. Today, the National Council of Teachers of Mathematics (NCTM) recommends the use of manipulatives to teach math at all grade levels to teach from NCTM standards: problem solving, communicating, reasoning, connections, and estimation. Closer to our time, Italian educator Maria Montessori brought manipulatives to early childhood learning over a hundred years ago with great success. The ancient Romans and Greeks conceived of counting boards and eventually the abacus, and the Chinese abacus that came into use centuries later is thought to be an adaptation of the Roman version.

Alternatively, students can experiment with numbers and see how they change as they move one number from place to place. Students can practice placing a dictated number on the chart and confirm whether they’ve done so correctly by reading the written number. The interactive place value chart shows the number, composition of the number, and written number below the chart. Drag numbers around or off the chart to change the number. ![]() Depending on where you place it, zeros will automatically appear to show the value of the number. To use the chart, simply click and drag a number into the chart. This manipulative place value chart offers a visual representation of ones, tens, hundreds, thousands, ten thousands, hundred thousands, and millions. Zeros are placeholders for places without a value. When writing numbers, the value of each digit depends on its place. This interactive place value chart helps children develop an understanding of the value of each digit in a number.
