Learning Standards Standards

What does a student learn in ?

This is the year math stretches into bigger numbers and the first real work with fractions. Students add and subtract numbers in the thousands, multiply and divide using what they know about groups and place value, and start comparing fractions like 3/4 and 2/3 to see which is larger. They also measure with rulers, read graphs, and sort shapes by their angles. By spring, they can solve a multi-step word problem and explain why two fractions are equal.

Year at a glance
How the year usually goes. Every school and district set their own curriculum, so treat this as a guide, not official pacing.
  1. 1

    Place value and big numbers

    Students work with numbers up to a million. They read them, write them, compare them, and round them to a nearby ten, hundred, or thousand.

  2. 2

    Multi-digit multiplication and division

    Students multiply numbers like 36 times 27 and divide larger numbers by a single digit. Word problems start asking them to figure out which operation to use.

  3. 3

    Factors, multiples, and patterns

    Students break numbers apart into their factors and spot number patterns. They learn what makes a number prime and start noticing how multiplication tables connect.

  4. 4

    Fractions and decimals

    Students compare fractions, add and subtract them, and see how a fraction like one tenth is the same as the decimal 0.1. Money and rulers help make this concrete.

  5. 5

    Measurement and data

    Students measure length, weight, and time, and switch between units like feet and inches or hours and minutes. They read graphs and answer questions about the data.

  6. 6

    Shapes, angles, and symmetry

    Students sort shapes by their sides and angles, measure angles with a protractor, and find lines of symmetry in everyday objects.

Mastery Learning Standards
The required skills a student should display by the end of Grade 4.
Standards for Mathematical Practice

  • Make Sense of Problems

    RI-MATH.MP.4.1

    Students read a math problem carefully, figure out what it's actually asking, and keep trying even when the first approach doesn't work.

  • Reason Abstractly

    RI-MATH.MP.4.2

    Students take a word problem and strip it down to numbers and symbols to solve it, then translate the answer back into what it means in real life.

  • Construct Arguments

    RI-MATH.MP.4.3

    Students explain why their math answer is correct and listen carefully to how a classmate solved the same problem. They can spot a mistake in someone else's reasoning and explain what went wrong.

  • Model with Mathematics

    RI-MATH.MP.4.4

    Students use math to make sense of real situations, like figuring out how much something costs or how long a trip will take. They draw pictures, write equations, or make tables to work through the problem.

  • Use Tools Strategically

    RI-MATH.MP.4.5

    Students choose the right tool for the job, whether that means a calculator, a pencil, or a quick estimate in their head. The goal is knowing which tool fits the problem, not just reaching for the same one every time.

  • Attend to Precision

    RI-MATH.MP.4.6

    Students say exactly what they mean: using the right math words, labeling answers with correct units (inches, dollars, minutes), and checking that their calculations are accurate.

  • Use Structure

    RI-MATH.MP.4.7

    Students spot patterns and hidden structure in numbers, shapes, and equations, then use what they notice to solve problems faster. Instead of starting from scratch each time, they recognize how the pieces fit together.

  • Express Regularity

    RI-MATH.MP.4.8

    Students notice when the same steps keep working the same way and use that pattern as a shortcut. Instead of solving every problem from scratch, they spot the rule behind the repetition and apply it.

K-8 Mathematics Content

  • Counting and Number

    RI-MATH.K8.4.1

    Grade 4 number work covers whole numbers, fractions, and basic negative numbers. Students read, compare, and work with these numbers using place value and number-line thinking.

  • Operations and Algebraic Thinking

    RI-MATH.K8.4.2

    Students use addition, subtraction, multiplication, and division to solve word problems and write number sentences that show their thinking.

  • Measurement and Data

    RI-MATH.K8.4.3

    Students read and build tables and graphs to answer questions about real data. They look for patterns in the numbers and explain what the information shows.

  • Geometry

    RI-MATH.K8.4.4

    Students sort and measure flat and solid shapes. They describe sides, angles, and faces using what they know about geometry.

  • Ratios and Proportional Relationships

    RI-MATH.K8.4.5

    Students use ratio reasoning to solve everyday problems, like figuring out how many supplies are needed for a class or how ingredients scale in a recipe. They apply this thinking to both real-life situations and math problems at the fourth-grade level.

Common Questions
  • What math should students know by the end of the year?

    Students should multiply and divide larger numbers, add and subtract fractions with the same bottom number, and solve word problems with more than one step. They should also measure with rulers, read graphs, and recognize shapes by their angles and sides.

  • How can families help with multiplication at home?

    Practice times tables in short bursts, five minutes at a time, until facts up to 12 come quickly. Use real situations like setting the table for 6 people with 3 utensils each, or counting tiles on the floor in rows.

  • What does it mean to work with fractions this year?

    Students compare fractions like 3/4 and 2/3, add fractions with the same bottom number, and see fractions in measuring cups, rulers, and pizza slices. At home, cooking and cutting food into equal parts gives plenty of practice.

  • How should multiplication and division be sequenced across the year?

    Start with fluency of basic facts, then move to multiplying two-digit by one-digit numbers using area models and place value. Save long division and multi-step word problems for the second half, once fact recall is solid.

  • Which skills usually need the most reteaching?

    Fraction comparison and multi-step word problems tend to need a second pass. Students often confuse the size of fractions when bottom numbers differ, and they miss steps in word problems when they rush past the question being asked.

  • My child gets stuck on word problems. What helps?

    Have students read the problem twice and say what it is asking in their own words before picking numbers. Drawing a quick picture or bar model often unlocks the next step, even for problems that look hard at first.

  • How do I plan measurement and geometry without losing time on number work?

    Weave measurement into number units when possible, such as multiplying to find area or adding fractions on a ruler. Save a focused geometry block for angles, lines, and shape classification later in the year.

  • How do I know students are ready for next year?

    Ready students can multiply a three-digit number by a one-digit number, add fractions with the same bottom number, and solve a two-step word problem without prompting. They can also explain their thinking, not just give an answer.
