2/3 × 9/10 = ?
Show them: Multiply tops: 2 x 9 = 18
Say: Multiply bottoms: 3 x 10 = 30
Say: Reduce 18/30 = 3/5
3/5
All four operations with fractions, mixed numbers, and decimal operations.
Grade 6 · approximate gradeKumon Math Level F (Fractions II & Decimals) is the 11th of 21 levels in the Kumon math program, where children learn all four operations with fractions, mixed numbers, and decimal operations. It typically aligns with grade 6 schoolwork, though Kumon places children by ability rather than age, so the grade is a guide, not a rule.
Level F builds directly on Math Level E: Fractions I and prepares children for Math Level G: Positive/Negative Numbers & Algebra Intro. 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.
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.
