Practical Math Foundation – Tiers 1 & 2

Practical Math Foundation – Tiers 1 & 2



Tier 1.  The TI 30XA is an inexpensive, yet powerful, calculator. The lessons in Tier 1 teach your student how to get the most out of this calculator, covering topics ranging from basic operations (addition, subtraction, etc.) and storing numbers in memory to working with fractions and trigonometry operations (SIN, COS, TAN).  Pre-Algebra is a great foundation for your student to create a solid future in mathematics. This course explains the basic rules for addition, multiplication, and the distributive law, as well as explaining fractions, squares, square roots, reciprocals, exponents, and other topics crucial to understanding higher level mathematics.

Tier 2.  Tier 2 is made up of three topics: Algebra, Geometry, and Trigonometry.

Algebra teaches students to apply a process, and students learn how to approach a mathematical problem. Students learn how to solve linear equations by applying topics learned in Tier 1 – addition, subtraction, multiplication, division, the distributive law, reciprocal, and exponents – as well as The Rule of Algebra. Students are also introduced to the SIN and COS functions, and how they are dealt with in linear equations.

Students already use geometry in their lives and most don’t even realize it. This course teaches students that when they understand the rules of straight lines and angles, parallel lines, triangles, and the Pythagorean Theorem, they can figure out a lot when given only a little bit of information. Algebra and Geometry are combined in utilizing similar triangles to solve a variety of problems, which is one of the most useful tools in industrial practical math. Geometry lessons teach students about polygons and their perimeters, area, volume, and surface area, as well as the formulas that govern them.

Some students are intimidated by the trigonometry functions SIN, COS, and TAN, but this intimidation is unnecessary! The trigonometry lessons clearly and concisely explain that these functions are simply ratios, and when given a little bit of information, your student can learn a lot about the triangles that use them. In addition, the Pythagorean Theorem, and the Laws of Sines and Cosines, aid in a student’s understanding of trigonometry.
