Geometry Concepts vs Visual Order of Operations

Geometry Concepts is an interactive learning system designed to provide instruction in mathematics at 7th grade through adult levels. The instructional goals for Geometry Concepts include several objectives. The primary objective for this app is to provide basic information about geometry through interactive lessons. Tap the notebook icon open dynamically illustrated lessons on each of the seven topics: Basic Concepts, Circles, Angles and Triangles, Lines and Planes, Area and Perimeter, 2-Dimensional Figures and 3-Dimensional Figures. Our goal in designing this app is to incrementally build an understanding of fundamental concepts by providing an easy-to-use format for exploring geometry. Tap the magnifying glass icon to explore a topic more deeply. Each of the images are interactive. Tap to reveal terms and key concepts. Tap the more info icon for detailed information about the highlighted term. We hope to support the development of a sense of confidence in each user's mathematical ability through a variety of educational approaches. Geometry Concepts includes a reference system, lessons, randomly generated quiz questions and an exploratory tool for open-ended investigations. Tap the tool icon on the main navigation screen to access a set of 12 interactive tools for exploring geometry concepts. Icons on the sides of the screen are used to change the investigation. Manipulated the tools to learn more about each concept. We think your students will enjoy learning with Geometry Concepts.

Visual Order of Operations helps students learn and practice the order of operations step by step. Students can evaluate randomly generated expressions or enter their own expressions. The app supports exponentiation, division, multiplication, addition, and subtraction with integers and decimals. Expressions can also include parentheses and nested parentheses. The app is designed to make each step visible. Students evaluate one operation at a time by tapping the operation they think should be solved next. If a student taps an operation that cannot be solved yet, the app explains why that choice is wrong. There are no penalties for wrong answers. After each step, the result of the current operation moves into the correct place and the rest of the expression moves down. This helps students see that only one part of the expression is solved at each step. Visual Order of Operations helps students understand that even a complicated expression can be handled one step at a time. Visual Operator Hierarchy: The app uses a “Boss Triangle” to show the order of operations visually. Exponents are shown at the top, multiplication and division in the middle, and addition and subtraction at the bottom. This gives students a visual model of the rules instead of relying only on mnemonics. Settings for Random Problems: - Allow multiplication - Allow division - Allow exponents - Allow negative numbers - Allow multi-digit numbers - Allow decimals - Allow parentheses - Allow nested parentheses Features: - Step-by-step order of operations practice - Randomly generated or manually entered expressions - Supports integers and decimals - Supports parentheses and nested parentheses - Visual explanation when an operation cannot be solved yet - Animated movement after each step - No penalties for wrong answers - Visual operator hierarchy with the Boss Triangle Other iDevBooks Math Apps: Other iDevBooks math apps include Visual Multiplication Table, Visual Fractions Decimals Percentages, Decimal Rounding, Whole Number Rounding, Column Subtraction, Column Addition, Long Division, Long Multiplication, Lattice Multiplication, Fraction Math, Partial Differences Subtraction, Partial Quotients Division, Partial Sums Addition, and more.
