G5–6 Math Lab

Students learn Pre-Algebra concepts by solving ratio, proportion, and basic equation problems written in English.

They also study factors and multiples, fraction and decimal operations, and solid figures, and write out solutions to written-answer problems in PEEL order.

Your child learns the same concepts in Korean school math and in English problems

Korean school math: G5–6

  • Ratios and proportions
  • Basic equations
  • Solid figures

Solving them again in English

  • Solve them in US-style English Word Problems
  • Pre-Algebra: use a letter for an unknown value and write the relationship between quantities as an equation

School units in Grade 5 and Grade 6

Korean school math units from Grade 5 (mixed operations, factors and multiples, fraction calculations, rectangular prisms) to Grade 6 (dividing fractions and decimals, ratios and proportions, solid figures)
  1. Grade: Grade 5

    Korean school math units: Mixed operations, factors and multiples, simplifying fractions and finding common denominators
    Adding, subtracting, and multiplying fractions; multiplying decimals
    Number ranges and rounding, averages and probability, patterns
    Congruence and symmetry, perimeter and area, rectangular prisms

  2. Grade: Grade 6

    Korean school math units: Dividing fractions and decimals
    Ratios and proportions, graphs
    Prisms and pyramids
    Volume and surface area, solid figures from different views
    Circles, cylinders, cones, and spheres

Solve independently, then redo mistakes

Each class starts with the last assignment and the problems your child got wrong. After learning the new concept from examples, your child solves key problems and applied problems.

How students solve an English word problem

  • Find the conditions

    Students read the English word problem and mark the given information and the value to find separately.

  • Set up the equation

    Students turn the conditions into a proportion or an equation with an unknown x.

  • Redo problems they got wrong

    Students find whether the error was in the conditions, the equation, or the calculation, then solve again without help.

Explain the reasoning, out loud and in writing

After finding the answer, students explain out loud why they set up the equation. On written-answer problems, they write the solution in PEEL order.

Writing a solution in PEEL order

  1. Write the answer firstPoint
  2. Write the equation and calculations that support itEvidence
  3. Explain why they set up that equationExplanation
  4. Finish by checking that the conclusion answers the questionLink

Explaining the reasoning with English math terms

As in an English textbook example, students use the commutative property and the associative property to explain why they group and multiply 2·5 and 25·4 first.

A quiz every class checks what your child learned

Each quiz checks the answer and whether your child can explain why they set up the equation. Quiz results and instructor comments go to parents too. See how parents get progress updates
