4th Grade Math Skills Checklist

Fourth grade scales everything up: multi-digit multiplication, long division, fraction arithmetic, and decimals make their first appearance. Fluency from third grade gets put to work. Here is what most fourth graders work toward.

Multiplication & division

  • Multiply up to four digits by one digit, and two digits by two digits
  • Divide with one-digit divisors, including problems with remainders
  • Find factor pairs; recognize prime and composite numbers
  • Solve multi-step word problems and interpret remainders sensibly

Fractions & decimals

  • Generate and explain equivalent fractions
  • Compare fractions with different numerators and denominators
  • Add and subtract fractions and mixed numbers with like denominators
  • Multiply a fraction by a whole number
  • Write fractions with denominators 10 and 100 as decimals; compare decimals to hundredths

Place value & large numbers

  • Read, write, and compare numbers to 1,000,000
  • Round multi-digit numbers to any place
  • Understand that each place is ten times the place to its right

Geometry & measurement

  • Measure and sketch angles with a protractor
  • Classify shapes by lines and angles; identify lines of symmetry
  • Use area and perimeter formulas for rectangles
  • Convert measurements within one system (km to m, hours to minutes)

How parents can help

  • Long division falters when multiplication facts are shaky — five minutes of fact review pays off double here.
  • Cooking is fraction practice with a reward: half the recipe, double the recipe.
  • Ask what a remainder means in the story — "3 buses and 12 kids left over" is where division becomes thinking.

Checklists for other grades

Frequently asked questions

My fourth grader struggles with long division. Where do I start?

Check multiplication facts first — long division is mostly multiplication and subtraction in a trench coat. If facts are solid, slow the algorithm down and narrate each step's meaning ("how many groups of 7 fit in 45?") before worrying about speed.

Fractions seem much harder this year. Is that expected?

Yes — fourth grade moves from naming fractions to operating on them. Visual models (number lines, fraction strips) should stay on the table all year; the arithmetic sticks when the picture comes first.
