EXAMPLE 01A parent walkthrough
Solve: 2x + 3 = 15
Show them: Subtract 3 from both sides: 2x = 12
Say: Divide both sides by 2
Say: x = 6
FINAL ANSWER
x = 6

What is Kumon Math Level H?
Kumon Math Level H (Linear Equations) is the 13th of 21 levels in the Kumon math program, where children learn solving linear equations, simultaneous equations, and inequalities. It typically aligns with grade 8 schoolwork, though Kumon places children by ability rather than age, so the grade is a guide, not a rule.
Level H builds directly on Math Level G: Positive/Negative Numbers & Algebra Intro and prepares children for Math Level I: Factoring & Quadratics. It is one of 21 Kumon math levels covered in this independent parent guide series.
This is an independent parent guide, not an official curriculum or placement assessment. Topics and pace can vary; your child’s instructor can confirm their current work.
- Solve 2x + 3 = 11
- Solve simultaneous equations by substitution
- Solve simultaneous equations by elimination
- Solve and graph inequalities
- Turn word problems into equations
How do I help my child with Level H?
Work through one example together, then let your child try the next one alone. A few small problems to try together — let your child attempt each first, then use these prompts when they need a nudge.

EXAMPLE 02A parent walkthrough
Solve: x + y = 10 and x - y = 4
Show them: Add the equations: 2x = 14, so x = 7
Say: Substitute: 7 + y = 10, so y = 3
Say: Check: 7 - 3 = 4 ✓
FINAL ANSWER
x = 7, y = 3
How can parents support Level H?
Short, calm, and daily beats long and pressured. These small habits make Level H stick — pick one and start tonight.
Substitution for one easy equation, elimination for matching coefficients
