6th-8th Math

October 5, 2022 | Sam Choi


Sixth grade

Students explore new concepts with numbers and operations while continuing to work with whole numbers, fractions, percentages, and measurements. Number theory work includes primes, factors, and multiples. Extensive work with geometry, fractions, statistics, and probability are also important.

Units of Study

Number Sense, Rational Numbers, Ratio and Proportions, Expressions, Equations and Inequalities, Geometry, Statistics

Seventh grade

Students perfect skills and concepts learned in previous years, and they undertake an extensive pre-algebra curriculum. Students focus on proportional relationships and linear growth patterns. They study the order of operations and begin to solve simple equations and inequalities. Geometry concepts are also explored, including the Pythagorean theorem and circle geometry.

Units of Study

Integers, Rational Numbers, Real Numbers, Exponents and Scientific Notations, Algebraic Expressions, Equations and Inequalities, Ratio and Proportions, Percents, Geometry, Probability and Statistics, Linear Equations, Proportional Relationships and Lines, Functions and Relations

Eighth grade 

Algebraic study, which can be thought of as the “science of comparison and reduction,” begins in early grades and ends with a formal study in the eighth grade year. Such study includes work with variables, expressions and equations, transformation of equations, polynomials, linear and quadratic equations, Cartesian planes, and set theory.

Units of Study

Expressions and Operations, Equations and Inequalities, Transformations and Congruence, Dilations and Similarity, Right Triangles and Volume, Functions, Linear Functions, Exponents and Radicals, Exponential Functions, Descriptive Statistics, System of Equations and Inequalities, Polynomials, Quadratics


Students will be assigned daily homework assignments from either the Mathspace program or their textbook.  Students are expected to work 30 to 45 minutes per day, split between the home and classroom.

Teacher, Grade 8; Science, History, and Ethics, Sixth to Eighth Grades

Mr. Choi has been teaching for over twenty years. Prior to Mustard Seed, Mr. Choi taught at a high school and a middle school for students with language based learning differences. He has also taught at an after school tutoring center and a standardized test prep center.

Over his career, Mr. Choi has taught high school Chemistry, Anatomy and Physiology, Computer Programming, Algebra I and II, Geometry, Pre-Calculus, and US and European History. He has also taught middle school PE, Health, Earth Science, Physical Science, Life Science, Pre-Algebra, Algebra, World History and Language Arts, as well as Ethics, Civics, Economics, Christian Studies and Geography.

Mr. Choi enjoys running, watching movies, and cheering for the Kansas City Royals and Chiefs; he has been an avid fan of these teams since 1980.
He is married to Abby Hall Choi and is the father of Noah (MSS Class of 2027) and Jacob (MSS class of 2030).
