Encouraging students to use critical thinking is more than an extension activity in science and math lessons, it is the basis of true learning. Teaching students how to think critically helps them move beyond basic comprehension and rote memorization. They shift to a new level of increased awareness when calculating, analyzing, problem solving, and evaluating.

CK-12 Foundation's Basic Algebra, Volume 1 Of 2 FlexBook covers the following six chapters:Expressions, Equations, and Functions - covers the relationships among expressions, equations, and functions when variables are present. Also explored is how these ideas can be shown on graphs. Properties of Real Numbers - covers various forms that rational numbers can assume, including fractions, integers, and square roots. Also considered are different operations for manipulating rational numbers. Linear Equations - introduces students to methods of solving simple equations involving variables. Also covered are ratios, scale, and the percent equation. Graphing Linear Equations and Functions - provides students with a more in-depth understanding of equations by introducing coordinate plane graphing concepts such as intercepts and slope. Writing Linear Equations - focuses on writing various forms of equations based upon real-world data and already existing lines. Students will also learn about predicting data using a fitted line. Linear Inequalities and Absolute Value; An Introduction to Probability - covers operations of inequalities, including addition, subtraction, multiplication and division. These principles are then applied to absolute value and probability.

This gives students a real life example of how to use proportions

Wikis are the most popular Web 2.0 tool being used in science and math classrooms. Based on a survey of readers - 43 percent use them to support their teaching and student learning. A Wiki is appealing, encourages participation, supports collaboration, and promotes interaction by students who love to use technology. By the way - this includes most students today!

A well-organized collection of 76 short videos demonstrating different pedagogical methods for teaching operations with fractions. Includes cool methods such as double number line and equivalent ratios.

This tool enables K-6 students to build visual models of word problems. There are hundreds of built-in math problems covering thirty-six different categories. Videos explain how to model each problem type. The full screen feature makes this application compatible with interactive white boards.

This is an incredible collection!!!
