Simultaneous Equations vs Math Geometry

Simultaneous Equations are a set of equations with two or more variables for which there are values that can satisfy all the equations simultaneously. The Simultaneous Equations app is an interactive tool designed to help teachers introduce the concepts related to simultaneous equations and demonstrates two methods for solving them. It provides students with an interactive learning device to help them better understand these important concepts. While using the app students set up the definitions of two lines. The lines are plotted on a coordinate grid. The coordinate pair for the intersection of the two lines represents the solution for the simultaneous equations. The Elimination and Substitution Methods are demonstrated. Designed in California by Dr. Fred Ventura, Simultaneous Equations is one of the apps in the Math Power Series. Simultaneous Equations turns your iPad into a mathematical playground for introducing the coordinate plane, ordered pairs, slope, y-intercept, and the graphical, substitution and elimination methods for solving simultaneous equations. The primary objective for this app is to provide a method for students to visualize simultaneous equations graphed on a coordinate grid and to learn the substitution and elimination methods for finding a solution algebraically. Tap the table icon and begin defining an equation by using a slider to specify the slope and y-intercept of a line. Tap the plot button to graph the equation. Use the same procedure to define a second equation. Tap either the substitution or elimination icon to open a note and see the algebraic steps involved in finding the solution. Tap the question mark icon to start the quiz and measure a students understanding using randomly generated problems. Tap the notebook icon to begin reading an illustrated lesson that includes information about real-world applications for simultaneuos equations.. Simultaneous Equations turns your iPad into a power tool for teaching the concepts related to solving simultaneous equations using the graphical, substitution and elimination methods. Use Simultaneous Equations to create a presentation while illustrating and discussing the key principles of analytic geometry. Simultaneous Equation is perfect for algebra students in middle school and high school classrooms. Enrich your mathematics curriculum with the power of Simultaneous Equations!

“Math Geometry: Learning 2D and 3D Shapes” is designed for school teachers and children aged 5-10 years to study 2D and 3D shapes, and the attributes of shapes. The app contains the hi-quality figures and provides a fun and interactive way to learn the shapes, so your kids will love this app. The app provides following functionality / topics / concepts: • Learning and testing 2D Shapes and their attributes – sides and corners • Learning and testing 3D Shapes and their attributes – vertices, faces and edges • Ability to rotate any 3D shape in any direction – it is a fun and effective way to memorize each shape • Different question types: identifying a shape by a given picture, by a given name and by its attributes • Manage the test content – you can exclude/include a specific shape from the test content • Choose the number of questions – from 10 to 40 • Progress report – ability to see the latest and best student results by test type (2D / 3D) and by question type (shape names / attributes of shape) • Ability to see the correct answer, and learn the related shapes when the student makes a mistake. This option is configurable, so it can be switched off if required • Ability to reset the statistics • Sound control Enjoy!
