EXAMPLE 01A parent walkthrough
∫ 6x² dx = ?
Show them: Reverse the power rule: add 1 to power, divide by new power
Say: 6x³/3 = 2x³
Say: Add C: 2x³ + C
FINAL ANSWER
2x³ + C

What is Kumon Math Level O?
Kumon Math Level O (Integration) is the 20th of 21 levels in the Kumon math program, where children learn integration, definite integrals, and real applications of calculus. It typically aligns with university schoolwork, though Kumon places children by ability rather than age, so the grade is a guide, not a rule.
Level O builds directly on Math Level N: Limits & Differentiation and prepares children for Math Level X: Advanced Calculus. 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.
- Integrate polynomials
- Evaluate definite integrals and areas
- Use substitution method
- Apply calculus to motion problems
- Use the fundamental theorem of calculus
How do I help my child with Level O?
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
Evaluate ∫₀² 3x² dx
Show them: Antiderivative: x³
Say: Evaluate 2³ - 0³
Say: = 8
FINAL ANSWER
8
How can parents support Level O?
Short, calm, and daily beats long and pressured. These small habits make Level O stick — pick one and start tonight.
Integration is differentiation in reverse — always check by differentiating
Definite integrals give area under the curve
+C is not optional in indefinite integrals
