Fun with Picture Grids: Teaching the Addition of Fractions

An Introduction to Picture GridsWhy is it that mathematics often conjures up images of desperate students trying to solve seemingly impossible problems? The subject of mathematics often compels otherwise well-adjusted adults to grimace with the memory of futile hours spent poring over numbers that seem at once both meaningless and threatening. Fortunately, there is an alternative. Yes, Virginia, there is a Santa Claus. The impossible really is possible, and we can do more than tell our students to clap...

Pic-Jour Math: Pictorial Journal Writing in Mathematics to Understand Pi

Come every fall, teachers of mathematics are confronted with oversized classes filled with students who vary in both their learning style and their way of communicating what they have learned. Teachers are challenged to recognize and exploit those differences or risk bored or confused students who lack any true mathematical understanding and may end up manipulating numerical symbols and equations by rote.Both experience and research in the past twenty years have demonstrated the clear effectiveness of using a multimodal, interactive approach...

The Link Between Art and Mathematics

There would seem to be an implausible relationship between art and mathematics. After all, the two domains seem to depend on vastly different thinking patterns. We do not question the interrelationship between science and mathematics, and the scientific process is clearly contingent on mathematics. How then did Ferguson (1977) manage to put together a historical review linking art and technology? Ferguson’s research indicates that inventors and art are more closely affiliated than either group would have us believe.Ferguson cites many examples...

Multiplication is even harder than addition and subtraction. They’re not ready to believe that these grids hold the magic that can ease the discomfort of multiplication. After all, students rarely...

He tells the students to solve the problem. One group takes the quarters grid and overlays it directly on top of...

Through the use of both rods and grids, Henry was able to help students visualize the mathematics problems that had previously remained a mystery.The good news is that Henry Goodman is back. The other news which...

Fun with Picture Grids: Teaching the Division of Fractions

Order a set at: http://www.hand2mind.com/catalog/product?deptId=&prodId=020272&q=picture+gridsPart V: Teaching Division with the Picture Grid ManipulativesTo understand division is simply to understand the wording. Division means “sets.” If we look at whole numbers and we ask, “What is 10 divided by 5?” We are simply asking how many sets of 5 can be found in 10? We know that the answer is 2. If we place this in a reality-based scenario, we have 10 pieces of candy and want to divide it among 5...
