About Marlene

My interest has always been in the teaching of mathematics, and how we learn and apply the tools of the subject. It has been interesting to observe and participate in the evolution of the pedagogy. In many ways the pedagogy has changed, and in some ways it has remained the same.

I started mathematics teaching in junior high school. I have taught junior high school, middle-school mathematics, high school mathematics, and freshman and sophomore college mathematics. Several mathematics subjects have been taught, including 7-9th grade general mathematics, algebra I, algebra II, pre-calculus, calculus, informal geometry, introductory or first-year statistics, mathematical methods. It has been interesting to see the emphases change in the algebras and statistics.

My current interests center around algebra, statistics, and international education. Functions, patterns, probability, binomial events, inferential statistics, and curriculum development hold particular interest to me. The history of mathematics and the approaches of diverse cultures to that subject are fascinating.

In tutoring, it is important to learn how each student learns and digests mathematics. It is exciting to find a student's modality (i.e. auditory, kinesthetic, and visual). When the modality is determined, then activities are developed around how the student learns. The modality is considered when explanations are given. My approaches can be described as a facilitator and having the student discover the major ideas.

Traditionally, there are junctures at which students encounter difficulty. The first juncture can occur at the fourth grade, and may continue to impact a student's career
through high school or freshman-year college. In tutoring, most weaknesses can be attributed to the 5 major junctures.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Algebra 1

Algebra I is generalized arithmetic. As such, it extends the coverage of linear equations, covered in pre-algebra, to multi -step equations. Algebra I also includes the foundation of graphing linear equations in two variables, using 3 methods of solving systems of linear equations, linear inequalities in one variable and two variables, and the rudiments of working with 2nd - degree equations (quadratic equations)in one variable. The study of polynomials includes all 4 operations with polynomials. Now algebra I includes some basic statistical terms and graphs.

Algebra 2

Algebra 2 is an extension of Algebra 1. As such, systems, functions, polynomial operations and number systems are covered, but to a greater extend. The topic, conic sections, is first introduced in Algebra 2. This topic is next handled in calculus.

Polynomials in the operations are reviewed, with more challenging examples included. Polynomial division (long and synthetic) is covered in Algebra 2. Occasionally, some Algebra 1 classes do cover the long division, in addition to division by a monomial.

Systems of Linear Equations involve 2, 3 and 4 variables. Solving systems that have linear equations and quadratic equations is included. The solution methods include graphing, substitution, and elimination. But in addition to these 3 covered in Algebra 1, the matrix method and Gaussian elimination are covered in Algebra 2.

Functions are covered more extensively. The characteristics are emphasized. Polynomial functions and some transcendental functions are examined. Some emphases are the zeros of the functions and asymptotes.

The study of number systems includes radicals in the operations and the complex system. Complex numbers in the 4 operations serve as a review of operations with polynomials.

Conic sections are examined in Algebra 2. But recently there is a trend for some classes to omit this topic. The standard and general equations of conic sections is an emphasis.

Some statistical concepts are examined in Algebra 2. These topics may include probability and confidence intervals.

Elementary Math

Elementary math includes the 4 basic operations with whole numbers and fractions. The fraction work includes common fractions and decimal fractions. Fractions are compared and changed to lower terms. Common fractions are changed to decimal fractions and percents, and vice versa.

There are several geometric topics included in elementary math. There is shape recognition of polygons, prisms and pyramids. Three measures are studied: Perimeter of polygons, Area of triangles and rectangles, and Volume of prisms.

Parts of a circle are included in elementary math. The parts of a circle include a semi-circle and a quarter circle. The various line segments in a circle are covered, too. The perimeter (circumference) is calculated; and the formula for the area is studied.

There are statistical topics in elementary math, as well. The measures of central tendency (mean, median, and mode) are calculated and identified. The range for a data set is calculated, too.

Elapsed time is studied in elementary math. It is extended each year to include more detail.


I have been teaching geometry for more than 40 years. I completed geometry courses as part of my baccalaureate degree and one Master's degree. I did course reviews of Geometry curriculum for one of our 50 states. I have successfully tutored students in the WyzAnt's community in geometry. I have state certification in 3 states and the District of Columbia for teaching Geometry.


Pre - algebra is preparation for algebra 1. Operations with signed numbers is begun here. Operation with negative and positive common fractions occurs in algebra 1.

It is important that students understand and use the classes of whole numbers. The properties of zero and 1 are emphasized. Prime factorization of whole numbers is practiced.

The principles of equality are illustrated with the use of two-step equations and inequalities, percent and proportions. Some of the concepts include finding decimal and common-fraction equivalents of percent numbers, mark-ups, discount prices, percent of change, and scale drawings. Proportion problems are solved using the cross-product rule.

Geometric figures are examined for recognition of their properties. There are activities on the perimeter and area of plane figures. Practice with graphing lines in the coordinate plane is included.


A Pre - Calculus course begins with a rigorous review of Algebra II. These topics include the properties of the Real Number System, the more difficult factoring problems, and solutions of equations and inequalities.

Functions are examined in depth. Theorems, not an Algebra II topic, are discussed. Some theorems are even proven by mathematical induction. The functions include polynomial, rational, piecewise-defined, exponential, and logarithmic. Other topics are Functional characteristics, inverse functions, and operations with functions.

Pre-Calculus includes more study of trigonometry. DeMoivre's Theorem, Vectors, and the trigonometric form of a complex number are some topics. The area of triangles is extended to finding the area of any triangle, not just right triangles.

No pre-calculus class would be without its trig identities. Factoring is an integral part of verifying trigonometric identities. Identities are verified by using other identities, such as the Double Angle Identities and the 3 Pythagorean Identities.

Some pre-calculus courses include matrices and determinants. A course may include linear programming or sequences and series. The Binomial Theorem and the use of Pascal's Triangle are topics in sequences and series.

SAT Math

The SAT Math sections pull information, primarily from Algebra 1, Geometry, Algebra II, and simple rules in Probability. There is occasional use of some precalculus concepts.

In recent years, the focus is on application of concepts, rather than the steps required to execute that concept. You may be presented a problem, where you decide which concept is applicable for its solution.

It is helpful to know the following: Prime factorization of the integers, of algebraic polynomials, and the Pythagorean triples. It is helpful to know the various measures associated with geometric figures. These measures include area, perimeter & circumference, interior angle measure of polygons, linear measure in polygons and circles, and volume of prisms and cylinders.

It is helpful to know the characteristics of polynomial and transcendental functions. These characteristics include the zeros, possible asymptotes, and global behavior.

Reviewing your equation - solving skills is useful, as well. The equation-solving skills include linear and quadratic equations. Don't forget the usefulness of proportions.

Four test - taking strategies follow. Thorough knowledge of the well - known formulas saves time. Be aware that the problems increase in difficulty as you proceed through the section. So work the first 6 or 7 problems as quickly as possible, and bubble in your choice.


Statistics includes the gathering of data, describing data, and drawing conclusions and inferences about the population from the data. There are 2 basic parts to statistics: descriptive and inferential.

Descriptive statistics includes various graphs, measures of central tendency, and measures of variation, discrete and continous distributions. Discrete distributions include the binomial, Poisson, and hypergeometric distributions. The most well - known continuous distribution is the normal distribution.

Probability is the bridge between descriptive and inferential statistics. Some of the probability topics include sampling - an important tool in inferential statistics. Events include independent and dependent events, mutually exclusive events, disjoint events. The addition and multiplication rules for working with various events is included in probability.

The major processes in inferential statistics are hypothesis testing and confidence intervals. Associated with hypothesis are the following: Null hypothesis and alternative hypothesis, level of significance, and the p - value. Topics include the z -procedures for drawing conclusions about the population mean, t - procedures for drawing conclusions about the means, z - procedures for proporions, chi - square tests, and the F-tests.


Trigonometry is essentially an opportunity to apply algebraic skills to right-triangle trigonometry and to circle trigonometry. The rudiments of right-triangle trigonometry are included in some Algebra 2 curriculum.

The algebraic skills are especially useful in solving trigonometric equations and verifying trigonometric identities. Be prepared to use your factoring skills in verifying identities. There are 8 different sets of trigonometric identities. The sine and cosine identities are used in all of these 8 sets. Algebraic skills are useful, also, in graphing trigonometric functions, showing their different transformations.
