Math Review of Representing Solid Figures

Overview Three-dimensional solid figures can be represented by the two-dimensional pattern of polygons that create them. The pattern, called a net, is a visual representation that illustrates the formula for the surface area of the three-dimensional figure. If the net were folded, it would produce that figure. Representation of Cylinders The net for a cylinder […]

English Review of Basic Writing Structures

Overview Writers use basic structures to put their ideas in order and present them. Some of those basic structures include chronological, sequential, comparative, causal (or cause-and-effect), categorical, and evaluative. Chronological and Sequential The simplest way to order ideas is to present them as they happen in time, with a beginning, middle, and end. Most stories […]

English Review of Transitions

Overview One of the ways to help the reader understand the points made or the direction the argument is going is by the use of transitions.  Transition words and phrases signal illustration, contrast, continuation, or conclusion. Illustration One of the ways to develop an idea is by illustrating examples.  They add more information about a […]

Science Review of Metalloids

Overview Metalloids are elements that have some properties of metals and some of nonmetals.  They are on the periodic table along the dividing line between metals and nonmetals. The most commonly recognized metalloids include the elements boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). Metalloids Elements are commonly classified as […]

Science Review of the Juno Mission

Overview The Juno probe entered orbit around the planet Jupiter on July 4, 2016.  Jupiter is the largest planet in the Solar System, and the Juno probe will study the magnetic fields of the planet, as well as clues to its origin and composition. The Juno Probe The Juno probe launched in August 2011.  Its […]

Math Review of Graphing Systems of Equations

Overview One of the ways to solve systems of equations is by graphing the equations on the same coordinate plane.  By graphing the equations, it is possible to tell whether they have no solutions in common, one solution in common, or an infinite number of solutions in common. No Solutions in Common These linear equations […]

Math Review of Parallel and Perpendicular Lines

Overview Parallel lines never intersect when they are graphed on the same plane, while perpendicular lines are lines that intersect at one point at right angles to each other.  Their linear equations have special relationships. Parallel Lines Parallel lines are lines in the same plane that have no points in common.  Suppose that one line […]
