Put on Your Thinking Caps | Math by Design Geometry Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you! Geometry can be divided into: Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper Solid Geometry is about three dimensional objects like cubes, prisms, cylinders and spheres. Point, Line, Plane and Solid A Point has no dimensions, only position A Line is one-dimensional A Plane is two dimensional (2D) A Solid is three-dimensional (3D) Why? Why do we do Geometry? Plane Geometry Plane Geometry is all about shapes on a flat surface (like on an endless piece of paper). Perimeter General Drawing Tool Polygons A Polygon is a 2-dimensional shape made of straight lines. Here are some more: The Circle Circle Theorems (Advanced Topic) Symbols There are many special symbols used in Geometry. Geometric Symbols Congruent and Similar Angles Types of Angles Transformations and Symmetry Transformations: Symmetry: Symmetry Artist

Braingenie 3D Shapes . Intro We live in a three-dimensional world. Every object you can see or touch has three dimensions that can be measured: length, width, and height. The room you are sitting in can be described by these three dimensions. The monitor you're looking at has these three dimensions. In the world around us, there are many three-dimensional geometric shapes.

Algebra Tutorials A brief explanationEven people who know how to deal with fractions actually prefer not to. Equations and inequalities are great when it comes to fractions because there is a way to get rid of them. This tutorial shows you how. Eliminating FractionsThe steps for eliminating fractions are: Okay, so step 2 makes no sense yet. Step-by-Step ExamplesEXAMPLE: What did we just do? EXAMPLE: Sometimes it's confusing if we're not working with like things. EXAMPLE:TIPThe most common mistake in this process is when students only multiply the left side of the equation by the common denominator. ONLINE PRACTICENone.

Algebra 1 Online! Henrico County Public Schools Welcome to the wonderful world of Algebra 1 Online! This course contains both content that reviews or extends concepts and skills learned in previous grades and new, more abstract concepts in algebra. Students will gain proficiency in computation with rational numbers (positive and negative fractions, positive and negative decimals, whole numbers, and integers) and algebraic properties. New concepts include solving two-step equations and inequalities, graphing linear equations, simplifying algebraic expressions with exponents, i.e. monomials and polynomials, factoring, solving systems of equations, and using matrices to organize and interpret data. Students will be actively engaged using concrete and virtual materials and appropriate technologies such as graphing calculators and computer software. Mathematics has its own language, and the acquisition of specialized vocabulary and language patterns is crucial to a student’s understanding and appreciation of the subject.
