DC Circuit Builder vs Fractions, by MLC

Design, build, and test circuits on your iPhone or iPad for free! "So that's how parallel circuits work!" - Physics student From Nerd Island Studios, LLC the creators of the top-rated "Step2Step Physics - Mechanics" for the iPad, comes an easy-to-use DC circuit builder: • Build and test series, parallel, and compound circuits • Visible charges flow through the circuit components • Voltmeters and ammeters behave like the real thing • Voltages are shown right on the circuit nodes • Bulbs glow brighter according to the amount of power they are dissipating Tested by high school teachers and students, DC Circuit Builder meets the need for a simple classroom tool to show students the basics of current and voltage, as well as the proper use of voltmeters and ammeters. www.nerdislandstudios.com

Fractions lets students use a bar or circle to represent, compare, and perform operations with fractions with denominators from 1 to 100. Choose the fraction model and number of equal parts. Use a color to select specific parts to show a fraction of the whole. Reveal or hide numeric labels as needed. Superimpose fractions upon each other to compare fractions or see equal parts. FEATURES • Use a bar or circle as the whole. • Divide each whole into anywhere from 1 to 100 equal parts. • Compare fractions and represent equivalent fractions. • Add, subtract, multiply, and divide with fractions. • Explore the relationship between fractions, percents, and decimals. • Select the size of the whole and the number of equal parts. • Hide and reveal fraction labels. • Hide and reveal work with resizable covers to create your own problems and model strategies. • Use the drawing tools to annotate work and show understanding. • Add equations, expressions, and descriptions with the math text and writing tools. • Share your work by saving an image or providing a share code to others.
