Grade 5

What Math Does a 5th Grader Learn? All 24 Topics, in Order

By Knomi Learning · Updated

The short answer

A 5th grader learns 24 math topics, in 6 units: Place Value and Whole Numbers, Division and Fractions, Decimals, Measurement and Data, Volume and Shapes and Coordinate Plane and Patterns. That is 62 smaller skills in all, taught in the order below, each building on earlier ones.

  • The earlier topics 5th grade leans on most: Adding Fractions (Grade 4), Multi-Digit Multiplication (Grade 4), Factors and Primes (Grade 4), Multi-Digit Division (Grade 4) and Multi-Step Problems (Grade 4).
  • All 62 skills are matched to a Common Core standard.
  • Every one of them has a full lesson on Knomi.

Unit 1: Place Value and Whole Numbers

1

Powers of Ten

The place-value pattern the whole grade runs on: each place is worth ten times the place to its right. The kid multiplies and divides by 10, 100 and 1,000 by shifting digits and writes powers of ten with exponents, which every decimal skill later leans on.

What it covers

  • Place Value and Ten-Times Relationships
  • Multiplying and Dividing by Powers of 10
  • Powers of Ten with Exponents

Builds on

  • Grade 4: Understanding Place Value
  • Grade 4: Reading and Writing Multi-Digit Numbers
  • Grade 4: Comparing and Ordering Whole Numbers
  • Grade 4: Multiplying by 10s, 100s, and 1,000s
  • Grade 4: Dividing Multiples of 10, 100, and 1,000
  • Grade 4: Multiplication Facts to 12 × 12
  • and 1 more

Whole-Number Fluency

Keeps adding and subtracting big numbers sharp and builds the habit of estimating before computing. Grade 5 has no new standard here: it is the safety net under every algorithm in the grade, so a wildly wrong answer starts to feel wrong.

What it covers

  • Adding and Subtracting Large Numbers
  • Rounding to Estimate Answers

Builds on

  • Grade 4: Adding Multi-Digit Numbers
  • Grade 4: Subtracting Multi-Digit Numbers
  • Grade 4: Rounding Whole Numbers
  • Grade 4: Estimating Products
  • Grade 4: Estimating Quotients

Multi-Digit Multiplication

The multiplication algorithm becomes a tool the kid trusts: area models first, then the standard algorithm for 2-digit, 3-digit and bigger factors, with an estimate to catch slips. It is the engine under long division, decimal multiplication and volume.

What it covers

  • Two-Digit Multiplication
  • Multiplying Large Numbers

Builds on

  • Grade 4: Multiplying 2-Digit by 2-Digit Numbers
  • Grade 4: Multiplying 3- and 4-Digit by 1-Digit
  • Grade 3: Distributive Property with Arrays

4

Numerical Expressions

Math grows a grammar: parentheses, brackets and braces decide what happens first, and an expression becomes a way to record a calculation and to compare two without working them out. Grade 6 algebra starts here.

What it covers

  • Expressions and Grouping Symbols
  • Writing and Interpreting Expressions

Builds on

  • Grade 4: Multiplication Facts to 12 × 12

5

Factors and Primes

How whole numbers are built: divisibility tests, factor trees down to primes, and the greatest common factor and least common multiple that make simplifying and common denominators quick. Common Core puts this in Grades 4 and 6; Knomi keeps it here as the fraction toolkit.

What it covers

  • Divisibility Rules
  • Primes and Prime Factorization
  • Common Factors and Multiples

Builds on

Unit 2: Division and Fractions

6

Fraction Foundations

Fractions become numbers: 3/4 is 3 divided by 4, equivalent fractions name the same amount, and a common denominator makes the pieces the same size. All Grade 5 fraction work, and long division's remainders, lean on these three ideas.

What it covers

  • Fractions as Division
  • Equivalent Fractions and Simplest Form

Long Division

Long division finished: one-digit divisors to fluency, two-digit divisors with trial quotients, four-digit dividends, remainders written as fractions when the story wants it, and multi-step problems that use the whole toolkit.

What it covers

  • Division with One-Digit Divisors
  • Division with Two-Digit Divisors
  • Long Division with Larger Dividends
  • Multi-Step Word Problems

Unit 3: Decimals

11

Understanding Decimals

Place value keeps going past the decimal point: tenths, hundredths, thousandths, each a tenth of the place before. The kid reads, compares and orders decimals and slides them along powers of ten. 0.4 beats 0.39 even though 39 beats 4.

13

Decimals and Percents

Three names for one amount: 3/4, 0.75 and 75%. The kid converts between fractions and decimals and meets the percent sign as hundredths in disguise; percents are Grade 6 in Common Core, but kids this age meet them everywhere.

What it covers

  • Fractions as Decimals
  • Percents as Hundredths

Builds on

  • Grade 4: Decimals and Fractions on Number Lines
  • Grade 4: Tenths and Hundredths as Fractions

What it covers

  • Multiplying Decimals by Whole Numbers
  • Multiplying Decimals by Decimals

Builds on

  • Grade 4: Multiplying Fractions by Whole Numbers

  • Dividing Decimals by Whole Numbers
  • Dividing by Decimals

Unit 4: Measurement and Data

16

Unit Conversions

The grade's real-world capstone: prices and change, unit costs, and measurements in mixed units. The work is deciding which operation the story needs, converting along the way, and letting an estimate keep the answer honest.

What it covers

  • Decimal and Money Word Problems
  • Multi-Step Measurement Word Problems

Builds on

  • Grade 4: Measurement Word Problems

Unit 5: Volume and Shapes

Unit 6: Coordinate Plane and Patterns

23

Coordinate Plane

Two number lines meet and every point gets an address. The kid plots and reads first-quadrant points until (x, y) is automatic, then uses coordinates for maps and real data; swapping x and y is the slip to watch for.

What it covers

  • Generating and Comparing Number Patterns
  • Graphing Number Patterns
