**Handbook of Essential Mathematics**

Teachers: You and your students might come to value the Handbook of Essential Mathematics from the Air Force Research Laboratory (2006) at Wright Patterson Air Force Base in Dayton, Ohio. It's particularly relevant for subjects addressed on this page of resources. This free online handbook is open source and has three sections "that will well serve both students and teachers alike from early grades through early college" (p. 3). Those are described as follows:

"Section I, “Formulas”, contains most of the mathematical formulas that a person would expect to encounter through the second year of college regardless of major. In addition, there are formulas rarely seen in such compilations, included as a mathematical treat for the inquisitive. Section I also includes select mathematical processes, such as the process for solving a linear equation in one unknown, with a supporting examples. Section II, “Tables”, includes both ‘pure math’ tables and physical-science tables," including some "just to nurture curiosity in a spirit of fun." ... Section III,“Applications in Personal Finance”, applies the language of algebra to everyday finances. (p. 4)

** Are your students ready for algebra?**
Your students can find out by taking an
Algebra Readiness Test.
This test at algebra-class.com includes answers, and content to review
theory.

Watch the overviews and get materials related to the National Math Panel: Critical Foundations for Algebra, a great resource for improving mathematics instruction, especially for elementary educators and elementary mathematics specialists.

In *Foundations for Success*, the National Mathematics Advisory Panel (2008) set
an expectation for school algebra that "students to be able to proceed
successfully at least through the content of Algebra II" (p. xvii). Major
topics recommended for school algebra include:

- Symbols and Expressions: polynomial and rational expressions, arithmetic and finite geometric series.
- Linear Equations, including linear inequalities
- Quadratic Equations
- Functions: linear, quadratic, polynomial, simple non-linear, exponential, logarithmic, trigonometric, and fitting simple mathematical models to data
- Algebra of Polynomials. This study would also extend to include complex numbers and operations, and mathematical induction.
- Combinations and permutations, as applications of the binomial theorem and Pascal’s Triangle, and Finite Probability. (p. 16).

**The following algebra resources should help to achieve those recommendations.**

Algebra in Simplest Terms is a video instructional series for high school learners and above. There are 26 (free) videos, 30-minutes each, which provide a step-by-step look at algebra concepts.

real world, which is for middle and high school learners. Begin by viewing
videos that show how professionals working in fashion, videogame design, music production,
basketball, the restaurant business, and the special effects industry use
algebraic thinking. They present challenges connected
to their jobs to two teams of teens. "At that point viewers are encouraged
to try the challenges themselves using interactive tools provided on the *GET
THE MATH* website, before returning to the video to see the teams’ solutions.
Students can further explore the same algebra concepts through additional
interactive challenges on the website" (About section). The project

Lure of the Labyrinth is a free online adventure game for pre-algebra learners, also suitable for middle school. Math is embedded in a story line--it' in an eerie world where monsters want world domination at any cost. The only way students can prevent that from happening is by solving the puzzles. Students progress through three sections, or "wings." Each is related to a different math strand: proportions (including fractions and ratios), variables and equations, number and operations (including geometry, order of operations and modular arithmetic). Each wing includes three puzzles, and each of the puzzles has three levels, from easy to hard. There are resources for teachers to help implement the game and also a section for families. This game is a product of the Learning Games to Go project, funded by a Star Schools grant from the U.S. Department of Education, spearheaded by Maryland Public Television.
