Hello, Students and Parents,

My name is Tim, and I have been teaching and tutoring for 12 years. I have studied mathematics up to calculus in school. I taught at Narbonne High School in the Los Angeles Unified School District for several years. I taught algebra and geometry. I also taught algebra and geometry for the Centinela Valley Union High School District in Lawndale, California. I have taught calculus as a substitute teacher. I have tutored both privately and for agencies. I privately tutored a student from Adams Middle School and Redondo Union High in pre-algebra and algebra. I also tutored an adult student who was reviewing for an exam in algebra. I have worked for A+ and Club Z tutoring agencies, tutoring mostly pre-algebra, algebra, and geometry. I have been tutoring for the Ford Learning Academy in geometry and pre-calculus for the past six years. I have also tutored chemistry there. I also am good at English grammar and social studies. I have always been interested in history. I have tutored occasionally in both subjects.

I have several teaching methods. First of all, I am patient. I was a student once and remember some of the difficulties students face. I think the best approach is to draw pictures and diagrams, especially with triangles. This has been especially helpful in the teaching of finding lowest common denominators to add unlike fractions. I use box diagrams to solve work and rate problems. I use the flip-and-multiply method to explain dividing fractions. I have a lot of experience tutoring in proofs of congruency of triangles. I am also skilled at teaching about logarithms and exponents, showing students how to set both sides of an equation to a common base to solve.

Sincerely,

Tim

I have experience tutoring the SAT, GED, and ASVAB, the armed services entrance test. Mathematics is my specialty. I am skilled at tutoring in changing percentages to fractions and decimals, rates, and direct and inverse proportionality problems.

I have tutored all levels of mathematics. I have tutored SAT mathematics. I know how to demonstrate strategies that will help students save time on tests.

I have a good knowledge of Algebra I. My favorite areas to tutor are linear equations and solving simultaneous equations. I am good at explaining how to transform a linear equation in slope-intercept form into standard form. I demonstrate how to solve simultaneous equations both by substitution and elimination. I also enjoy showing how to solve work and rate problems using the box diagram.

I have good experience tutoring Algebra II. I am familiar with both arithmetic and geometric series and finding sums of sequences. I am familiar with the equations of circles, ellipses, and hyperbolas and identifying when they are centered away from the origin. I am also skilled at identifying the focus and directrix of a parabola. I am skilled at identifying reference and coterminal angles of a given angle in trigonometry.

Hello. I have experience tutoring in achievement tests, including the GED and SAT. I am strongest in mathematics, but also have good knowledge of other subjects. Please contact me if you need an ASVAB tutor.

I have a good knowledge of calculus. I took a four-semester course in the subject. The derivative of a function is the slope of the tangent to a curve at a particular point on the curve. The integral of a function is the area under the curve. Calculus has real-life applications. The equation d = 1/2a*t^2 can be used to find how far an accelerating body falls in time t.

I am a credentialed Single Subject Mathematics teacher. I scored a 199 out of 240 on the CBEST. I also have experience tutoring the SAT, GED, and the ASVAB the armed forces qualifying test. I am especially strong in the Mathematics portion.

As an engineer, I studied chemistry as part of my undergraduate curriculum. I have tutored the subject before. I still remember atomic numbers and masses and how to balance chemical equations. I can tutor general chemistry confidently.

I have a good foundation in Elementary Mathematics. When tutoring, I stress that multiplication/division, addition/subtraction, and squares/square roots are inverse functions, so one function "undoes" the other. Operations are always performed in pairs, so when dividing by a fraction, the fraction to be divided by is "flipped," then division is changed to multiplication. I stress using the decimal point as a guide post in lining up numbers in their proper decimal places when adding or subtracting.

I have a lot of experience tutoring English. I like to stress proper grammar and usage. I notice a lot of usage errors, such as their, they're, and there. "They're going to take their vacation over there" demonstrates the correct usage. I also like to emphasize learning root prefixes and suffixes. This allows students to use the definitions of words they know to predict the definitions of new words.

I have experience tutoring the GED. I have found it a rewarding experience. Students who take the GED have realized the value of education and are pursuing a degree on their own. I am strongest in the mathematics portion but can also tutor the English portion of the test with confidence.

I have a good background in geometry. I taught it during my student teaching and have been tutoring it for the last six months. I am good at proofs using the alternate interior angles theorem, reflexive property of congruency, and the side-angle-side and angle-side-angle postulates. I am skilled at finding areas and interior angle measures of regular polygons. I am also skilled at trigonometry, which is often included in a geometry curriculum.

I have been playing classical guitar for nearly 30 years. I have taken lessons for two years, including a year with a graduate of the Cornish Institute in Seattle.

I would describe my ability as intermediate. I read music. I can play intermediate pieces. I can play a few pieces by Luis Milan and Valderrabano. Most Bach lute transcriptions are beyond my level, but I can play the bouree from the First Lute Suite.

I enjoy Physical Science. I have an Engineering degree, so my background in Physical Science is solid. I know mechanics. I am familiar with the concepts of force, mass, acceleration, and energy. I know fluid mechanics, including forces on dams and Bernoulli's equation. I am familiar with electricity, including parallel and series resistance, current, and voltage.

I have a good, solid background in Prealgebra. I have tutored several students in it. I am good at explaining how to convert phrases into algebraic expressions: 4 less than a number means x - 4, 3 more than a number means x + 3, etc. I recently spent a few lessons teaching a student how to solve simultaneous equations. There are two methods: substitution and elimination. I explained how to tell which method to use. If one equation is in slope-intercept form and the other in standard form, substitution should be used. If both are in standard form, elimination should be used. I explained how to find the least common denominator of one of the variables to multiply through to eliminate that variable from the equations.

I have a good knowledge of the subject. I am especially interested in logarithms and exponents. I am skilled at the change-of-base formula and the properties of exponents, products, and quotients for logarithms.

Proofreading is an important facet of any kind of written presentation. People judge by first impressions, so making the right impression the first time is important.

There are many essential rules in proofreading. In my experience, spelling errors are not as common as usage errors and redundancies. The most common usage error is their, they're, and there. "There comes a time when people need to evaluate their goals and decide where they're going in life" demonstrates correct usage. It is important to remember that an apostrophe in a pronoun indicates a contraction, not a possessive. Examples of redundancies are the words of after off and out after separate.

I feel I am well qualified to teach Reading. I earned a Bachelor of Science. I also earned a Single-Subject teaching credential, which required a good amount of reading. I read a metropolitan newspaper daily and enjoy books on history and current events.

I have tutored a few students specifically in SAT Math. One student received a 1250 SAT score and was accepted to UCLA. The test has problems that can be solved quickly by taking the right approach. Examples are if one angle is asked for in a right triangle, it can be found by realizing the sum of the two acute angles must be 90 degrees. I stress the importance of knowing the basic ratios of isosceles right and 30-60-90 triangles.

Trigonometry can be a difficult subject when a student first encounters it. I remember some confusion I had. To explain sine and cosine, I ask the student standing in the corner of a room where the angle is, looking toward the far wall. The far wall is the OPPOSITE, the wall closest to their right shoulder is the ADJACENT, and the wall closest to their left shoulder is the HYPOTENUSE. The opposite and adjacent sides make up the right angle, and the hypotenuse is the remaining side. Another confusing concept is the inverse sine or arcsin function. Arcsin(sin x) = x. I tell students that sin and arcsin are opposite functions like square and square root.
