A chalkboard filled with equations and graphs

Math

Your child solves English-language problems on the math concepts they learned in Korean school and practices explaining why each solution works.

Grades 1–6 cover operations, fractions, and ratios; grades 7–9 cover equations, functions, and geometry; grades 10–11 cover the Korean high school courses Common Math, Algebra, and Calculus. At every level, your child works with English math terms and word problems too.

Learning steps and assessments

From Korean school concepts to English problems, step by step

Steps your child already understands get a quick check, and lessons start at the step they need.

At this step, your child

  1. StepReview Korean school concepts and key problem types
    At this step, your child
    Works through the concepts and key problem types from Korean school again.
  2. StepLearn English math terms
    At this step, your child
    Learns the English math terms for the same concepts.
  3. StepSolve English word problems
    At this step, your child
    Finds the conditions in English word problems and sets up equations.
  4. StepWrite out the reasoning: PEE and PEEL
    At this step, your child
    Writes their reasoning as a PEE answer (Point–Evidence–Explanation). In PEEL, they add a Link sentence.
  5. StepApply it to AP, IB, A Level, and competition problems
    At this step, your child
    Uses the same concept to solve AP, IB, A Level, and competition problems.
Functions unit example: Korean concepts and English course terms

Korean school concepts

  • Linear and quadratic functions
  • Drawing graphs
  • What a function's equation means

English terms and AP, IB, and A Level notation

  • Function, Independent Variable, Dependent Variable
  • Slope, Intercept
  • Function notation f(x), Domain, Range, Graph Transformation
  • Exponential Function, Logarithmic Function, Trigonometric Function

How your child learns one unit, step by step

Students do extra problems on the types where they get stuck.

Five steps for working through a unit: concept check, core problem types, applications, advanced problems, and a final check
  1. Step: Concept check

    At this step, your child: Goes over the last assignment and problems they got wrong, then checks key concepts with questions and a quiz.

  2. Step: Core problem types

    At this step, your child: Applies the concept to representative examples.

  3. Step: Applications

    At this step, your child: Uses the same concept on problems with changed conditions.

  4. Step: Advanced problems

    At this step, your child: Solves challenge and proof problems at their level.

  5. Step: Final check

    At this step, your child: Finishes the unit with a quiz that shows whether they understood it.

Quiz results and what your child is covering at school decide how much of the next class goes to review and how much to challenge problems.

Redoing problems they got wrong

  1. Solve the problems they need from the problem bankProblem Bank
  2. Find the problem types they often get wrong, and whyError Analysis
  3. Fix their concept notes and solve againRe-Practice
  4. Solve without help and explain the solutionMastery Check

After getting the right answer, your child explains the solution and proves it

Four solution-writing skills: finding the answer, explaining why the method works, writing the reason for each step, and proving the solution
  1. Step: Answer: Find the answer

    At this step, your child: Reads the conditions, sets up an equation, and solves it.

  2. Step: Reason: Explain why they chose that method

    At this step, your child: Answers in their own words when the instructor asks, "Why did you pick this method?"

  3. Step: Justify: Write the reason behind each step

    At this step, your child: Answers "Why does this equation hold?" and writes the reason for each step.

  4. Step: Prove: Write the whole solution as a complete proof

    At this step, your child: Writes the proof from start to finish in logical order.

Filling concept gaps at your child's level

What students learn

  • AreaK–G1 and G1–6 math
    What students learn
    Students learn number sense and operations, fractions and decimals, ratios and measurement, shapes, and reading data, working on the problem types that come up most often.
  • AreaPre-Algebra, KS3, algebra, geometry
    What students learn
    Students learn numbers and proportion, equations and functions, and shapes, derive formulas themselves, then solve basic, applied, and challenge problems.
  • AreaSchool math and test prep
    What students learn
    Students work on school concepts alongside practice test problems, and redo the problem types they got wrong after hearing the explanation.

Each child gets the mix of Main (core lessons), Gap-Repair (filling concept gaps), and Challenge (harder problems) that fits them.
