Summary:

This document reviews the "Multiply Fractions JavaScript Simulation Applet HTML5," an interactive online tool designed for mathematics education, specifically focusing on the multiplication of fractions. The applet is designed to be embedded in webpages and is intended to help students visualize and understand the process of multiplying fractions. The resource also exists as part of a larger collection of Open Educational Resources (OER) and Open Source Physics (OSP) materials developed in Singapore.

Key Themes and Ideas:

• Interactive Learning: The core function is to provide an interactive environment for learning about fraction multiplication. Students can manipulate numerators and denominators using combo boxes and observe the resulting changes in the equation and visual representation.
• Visualization: A key feature of the applet is its emphasis on visual representation. The "total numerator is shown as the brown area, while the new denominator as the whole thing." This helps students connect the abstract mathematical concept to a concrete image.
• Editable Equation: The applet includes an editable equation, meaning students can directly interact with the numbers, reinforcing the link between numerical representation and visual change. "To edit the numerator/denominator, click on the combo boxes."
• Teacher Resources: The resource provides information "For Teachers" including instructions and sample learning goals. This suggests the simulation is designed with classroom integration in mind.
• Embeddable and Accessible: The applet can be easily embedded into webpages via an iframe, making it accessible for online learning environments. The link to embed is provided in the document: <iframe width="100%" height="100%" src="https://iwant2study.org/lookangejss/math/ejss_model_multiplyfractions/multiplyfractions_Simulation.xhtml " frameborder="0"></iframe>
• Open Educational Resource (OER): The resource is part of a broader initiative focused on providing freely accessible educational materials.
• JavaScript/HTML5 based: This indicates the simulation is built using modern web technologies, making it compatible with a wide range of devices and browsers.
• Credits: The document gives credit to Francisco Esquembre and Felix_J_Garcia_Clemente. "This email address is being protected from spambots. You need JavaScript enabled to view it. ; Francisco Esquembre; Felix_J_Garcia_Clemente"
• Reset Functionality The document explains how to reset the simulation: "Simply click the refresh button in your browser."

Important Facts/Details:

• Functionality: The applet allows users to change the numerator/denominator by clicking the combo boxes. When the denominators are changed, the equation and solution changes.
• Visual Representation: Denominators and numerators are represented visually via brown areas for the numerator and the whole area for the denominator.
• Target Audience: The resource is suitable for students learning about fraction multiplication. The presence of a "For Teachers" section suggests it is intended for classroom use.

Multiply Fractions Simulation FAQ

• What is the purpose of the Multiply Fractions JavaScript Simulation Applet HTML5?
• The applet is designed to help students visualize and understand the process of multiplying fractions. It allows users to manipulate the numerators and denominators of two fractions and observe how the product changes visually, with a brown area representing the total numerator and the whole area representing the new denominator.
• How can I interact with the simulation?
• The equation displayed in the applet is editable. You can change the numerators and denominators of the fractions by clicking on the combo boxes associated with each. Changing these values will update the equation and solution, allowing you to explore different fraction multiplications.
• What visual cues does the simulation provide?
• The simulation visually represents the multiplication of fractions by showing the total numerator as a "brown area" and the new denominator as the "whole thing". This helps users connect the abstract concept of fraction multiplication with a concrete visual representation.
• How does changing the denominators affect the visual representation?
• Changing the left denominator modifies the initial equation and solution. Changing the green denominator further affects the results, reducing the "brown area" representing the numerator proportionally. This illustrates how multiplying fractions results in a new fraction with potentially smaller numerator and denominator values.
• Where can I find other related resources?
• The resource mentions a GeoGebra applet at https://www.geogebra.org/m/T8ZUpxVv , which provides another interactive way to explore fraction multiplication.
• How can I embed this simulation on my own webpage?
• The page provides an <iframe> code snippet that you can copy and paste into your webpage's HTML to embed the simulation. The provided code <iframe width="100%" height="100%" src="https://iwant2study.org/lookangejss/math/ejss_model_multiplyfractions/multiplyfractions_Simulation.xhtml " frameborder="0"></iframe> will embed the simulation.
• Who created this simulation and where can I find more like it?
• The simulation was created by Francisco Esquembre and Felix_J_Garcia_Clemente. The broader Open Educational Resources / Open Source Physics @ Singapore project hosts this and many other interactive simulations across various science and math topics.
• What other kinds of interactive simulations are offered by Open Source Physics @ Singapore?
• The website offers a wide variety of interactive simulations and applets covering topics from physics (mechanics, electromagnetism, waves, optics) to mathematics (fractions, geometry) and even simulations related to chemistry and biology. Examples include simulations of projectile motion, collisions, electric circuits, wave phenomena, genetics, and more.
