Dominion - Know your tutor
I’m Dominion Onyejiaka, an experienced online math tutor with 3+ years of teaching students across multiple grade levels, from elementary foundations to high school and first-year university courses. I’ve supported learners in Algebra, Geometry, Trigonometry, Pre-Calculus, and Calculus by breaking concepts into clear, step-by-step methods that build real understanding (not just memorization). My sessions are personalized to each student’s goals, whether that’s catching up, getting ahead, or preparing for quizzes and exams, with targeted practice, guided problem-solving, and frequent check-ins to track progress. I use exam-style questions, timed drills, and “teach-back” techniques to strengthen confidence and accuracy. Students and parents appreciate my patient approach, structured lesson plans, and practical strategies that make math feel simpler and more manageable.

Class overview
My teaching methodology is structured, student-centered, and results-focused. I start by diagnosing what the student understands (and where the gaps are) using quick warm-up questions or a short skills check. Then I teach each concept using a clear step-by-step framework: explain the idea in simple terms, demonstrate 1–2 examples, and guide the student through similar problems until they can solve independently. I use active learning (the student talks through their steps), error analysis (we identify exactly why a mistake happened), and spaced practice to make skills stick. For exams, I run timed mini-quizzes, teach problem-recognition patterns, and show strategies for checking work quickly. I also create personalized practice sets and weekly goals, so students can track progress and build confidence over time. Tutor.

Mathematics concepts taught by Dominion
The student and tutor reviewed various mathematical concepts including solving linear inequalities, estimating from sample data, calculating the perimeter of a sector of a circle using degrees, and applying trigonometry (sine rule) to find unknown side lengths. They worked through several practice problems with the student demonstrating understanding and asking clarifying questions.
Solving Linear Inequalities
Properties of Inequalities
Estimating from Samples
Perimeter and Area of Sectors
Trigonometry: SOH CAH TOA
The student and tutor reviewed several mathematical concepts, including negative exponents, fractional bases with negative exponents, exponent rules for multiplication and division, properties of isosceles triangles, and formulas for the circumference and area of a circle. The student practiced solving problems related to these topics and discussed future lesson scheduling.
Understanding Indices and Exponents
Rules for Multiplying and Dividing with Indices
Properties of Circles: Circumference and Area
Isosceles Triangles and Angle Properties
The student and tutor worked through various mathematical problems, including geometry (Pythagorean theorem, trapeziums), algebra (formulas, inequalities), and number properties (significant figures, decimal places). The session involved practice problems and explanations to solidify the student's understanding of these concepts.
Quadrilaterals and Trapezia
Quadratic Inequalities and Graphs
Significant Figures vs. Decimal Places
Pythagorean Theorem
The Tutor and Student worked through A-Level Mathematics past paper questions, focusing on topics such as pressure, force, area calculations, percentage changes, geometric transformations (enlargement), financial word problems involving VAT and deposits, and ratio calculations. They practiced problem-solving strategies and the Student will prepare difficult questions for review in the next session.
Percentage Change Calculation
VAT and Compound Percentage Calculations
Ratio and Simplification
Pressure Calculation
The tutor and student worked through Edexcel GCSE Maths past paper questions, focusing on currency conversion and value for money calculations, followed by a geometry problem requiring the calculation of a trapezium's area using the sine rule. The tutor provided explanations and guided the student through the problem-solving steps, with plans to send notes for review.
