4th grade math practice that makes the facts work
Fourth grade is the year the multiplication facts that landed in 3rd grade get put to work. Multi-digit multiplication, long division, and serious fractions arithmetic all assume fluent times-table recall. Kids who left 3rd grade with shaky facts feel that gap immediately in 4th-grade word problems, where the arithmetic isn’t the question but is required to answer it.
What 4th graders learn in math
Common Core 4th grade (CCSS.Math.4.OA, 4.NBT, 4.NF) expects:
- Multi-digit multiplication. 2-digit × 1-digit, 2-digit × 2-digit, 3-digit × 1-digit.
- Long division with single-digit divisors and up to 4-digit dividends.
- Multi-digit addition and subtraction with whole numbers up to 1,000,000.
- Fractions: equivalent fractions, comparing fractions, adding and subtracting fractions with like denominators, multiplying a fraction by a whole number.
- Decimals: introductory work with tenths and hundredths.
- Factors and multiples within 100; recognize prime and composite numbers.
The Num Drill plan for 4th grade
The 4th-grade plan splits time across multiplication, division, and fractions, with addition and subtraction in maintenance mode.
Beginning of the year (audit week)
Run a one-week audit: 10-question quizzes at multiplication level 3, division level 2, addition level 4, and fractions level 1. The results tell you which skills need work. Most 4th graders arrive with shaky multiplication level 3 (full 1–12 tables) and need to consolidate that before anything else.
Daily core
- Multiplication level 3 until 90%+ accuracy and under 3 seconds per question. Without this, nothing else works.
- Once level 3 is solid: multiplication level 4 (2-digit × 1-digit) and division level 3 (full 1–12 division facts) on alternate days.
- Fractions levels 1–2 (reducing, like denominators) twice a week.
End of the year
- Multiplication level 5 (2-digit × 2-digit) for students ready.
- Division level 4 (long division of 2-digit dividends — see the long division practice page).
- Fractions level 3 (unlike denominators) introduced as 5th-grade prep.
Total daily time: about 5 minutes. The pattern that works for most 4th graders: alternate “multiplication day” and “division day,” with one fractions quiz layered in twice a week.
The long-division wedge
Long division is the operation 4th-grade parents most often write to us about. Almost every “my child is stuck on long division” conversation traces back to one or two missing multiplication facts — not the algorithm itself. If your 4th grader is freezing on 84 ÷ 6, the problem is usually that they’re uncertain whether 6 × 14 is 84 or 78. Fixing the underlying multiplication fluency fixes the long division. The long division practice page has a focused diagnostic.
Common parent questions about 4th-grade math
The other 4th-grade pattern: kids who can compute fractions when the denominators match but freeze when they don’t. Unlike denominators are the single biggest jump in elementary fractions, and it’s the wedge that decides whether 5th grade feels reasonable. Num Drill’s fractions level 3 drills exactly this; introduce it in the spring of 4th grade as 5th-grade prep.
