About Theodore


Bio

There is no one way to learn. Rote memorization is at one end of the spectrum and instantaneous complete understanding and insight of the topic is at the other end. There is a lot in between. People do not learn everything the same way - their own ability to learn changes from moment to moment and subject to subject.

Sometimes material is taught in our schools in a way that expects the student to learn in a specific manner and speed. That's great when those expectations are met. ...

There is no one way to learn. Rote memorization is at one end of the spectrum and instantaneous complete understanding and insight of the topic is at the other end. There is a lot in between. People do not learn everything the same way - their own ability to learn changes from moment to moment and subject to subject.

Sometimes material is taught in our schools in a way that expects the student to learn in a specific manner and speed. That's great when those expectations are met. But learning math doesn't always work that way. Math tends to build on previously taught (and hopefully learned) concepts and ideas. A lack of mastery of simpler ideas can create problems and frustration later on when more complex material is presented. Smoothing out those bumps in the learning process is what I am looking to do.

Though I haven't been in the classroom for many years, I continually teach in my job. When a topic doesn't click with someone I am working with, I look for other ways to get the concepts across. I look for a familiar starting point and work and rework the lesson as many different ways as needed.

Only when something has been learned have I the right to say I have taught.

Algebra 1,

Algebra 1

A solid foundation in this subject can be critical to how a student feels about high school math (and math, in general). Not fully undestanding a certain topic can lead to future frustration as the school year progresses. That frustration can turn into a loss of confidence toward math. Simplifying expressions, binomials, powers, factoring, linear equations, and graphing don't have to be difficult topics but if a student misses a key idea on a certain class day, it can quickly snowball. Many times, all it takes to get back on track is some focused review work.
Algebra 2,

Algebra 2

The second year of high school algebra introduces new concepts: logarithmic functions, exponential functions, series, sequences, conic sections (and learning how to sketch graphs of these curves). Sometimes the teacher and course move a little too fast for a student. A little help might be all it takes for the topics to make sense again.
Calculus,

Calculus

Derivatives, integrals, limits, and infinite series. It can be mind boggling at first, but once that nut is cracked, this area of mathematics becomes an amazing gateway to understanding so much in the sciences. You game?
Geometry,

Geometry

I taught high school plane geometry and still look for new and interesting ways to use the material on a daily basis. Angles, figures, lines, area, similarity can be found everywhere and knowing how to work with them can be fun and exciting.
Precalculus

Precalculus

Sequences, series, limits, vectors, polar coordinates - these are many of the topics taught in pre-calculus that become the later foundation of calculus. The transition into calculus can be made so much easier if each topic in pre-calculus is mastered.

Trigonometry

Trigonometry

Trigonometry studies the relationships between the sides and angles of a triangle. There is a lot more to it than just learning how to use the cos, sin, and tan buttons on your calculator. It is a rich subject and is used in many different areas of mathematics. As noted in Wikipedia: "Fields that use trigonometry or trigonometric functions include astronomy (especially for locating apparent positions of celestial objects, in which spherical trigonometry is essential) and hence navigation (on the oceans, in aircraft, and in space), music theory, acoustics, optics, analysis of financial markets, electronics, probability theory, statistics, biology, medical imaging (CAT scans and ultrasound), pharmacy, chemistry, number theory (and hence cryptology), seismology, meteorology, oceanography, many physical sciences, land surveying and geodesy, architecture, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development." It must be pretty useful stuff!

Knowledgeable and very engaging

I had a short lesson with Ted for AP Calculus, and I found him very knowledgeable and helpful. He understood what I was looking for in the session and it was very helpful for me. I highly recommend him.

Deepti, 1 lesson with Theodore

Amazing Tutor

Best tutor ever! My son said he really understood algebra 2 concepts after working with Ted. He explains the material in an easy, relatable way. So grateful to have found Ted.

Lori, 4 lessons with Theodore

Knowledgeable, patient and thorough

Ted has helped me to become more comfortable with pre-calc and calculus. I really appreciate his patience and the way he explains things to me until I understand.

Christine, 7 lessons with Theodore

great tutor!

Theodore is a great tutor who has a lot of experience in teaching. My son loves working with Ted. This is the fourth session. Thank you Teodore

Sharron, 4 lessons with Theodore

Great Teacher

Ted is a great teacher. When I gave him pin point questions, he talked me through them and helped me understand them.

Aman, 3 lessons with Theodore

Patient and Thorough Teacher

Ted is a fantastic tutor. I had him for college Calculus. He doesn't just tell you how to do something, he goes further to actually explain the concepts behind the material. He explains verbally, draws graphs and visuals, employs multiple avenues to teach a topic for a student with different learning strengths. He was very patient and took as long as we needed for me to understand the topics. On top of that, he's a great guy with a good sense of humor. Would highly recommend him to anyone!

Marissa, 4 lessons with Theodore

My son really liked the tutoring session

Ted is very patient, good at explaining complex subject. My son had been struggling with logorithm and complex numbers in Algebra 2. Luke is super happy with the results of the lesson.

Sharron, 4 lessons with Theodore

Awesome teacher, Very thorough

Great for feeling confident in work. And he goes by everything step by step and Is patient. Helps reinforce lessons at school that were not quite understanding. Overall awesome teacher!

Christina , 1 lesson with Theodore

Helpful tutor

Theodore S. quickly assessed my son's difficulties with the calculus. He tailored his teaching to what was needed. He has good rapport and clear explanations. 6 lessons so far have been quite helpful, and we will continue with Theodore until the end of the class.
