This is the year math stretches into fractions and decimals as real working numbers. Students add and subtract fractions with different bottom numbers, multiply and divide fractions in word problems, and do the same with decimals down to the hundredths. They also start finding the volume of boxes and plotting points on a grid. By spring, students can solve a recipe problem that mixes thirds and halves, and explain their answer.
Students see how each digit in a number is ten times the one to its right. They read and compare decimals out to thousandths and notice what happens to the decimal point when they multiply or divide by ten, a hundred, or a thousand.
Students multiply larger numbers and divide with two-digit divisors. They also add, subtract, multiply, and divide decimals to the hundredths place, using drawings and place value to check that answers make sense.
Students work with fractions that have different bottom numbers, like one half plus one third. They use number lines and pictures to find common ground between the fractions and solve word problems with mixed numbers.
Students multiply a fraction by a whole number or by another fraction, and they start to divide with unit fractions like one fourth. They also learn that multiplying by a number less than one makes the result smaller.
Students measure the space inside boxes by counting unit cubes and connect that to length times width times height. They also convert between units like inches and feet, and plot measurements on line plots to answer questions.
Students plot points on a grid using ordered pairs and use the grid to solve real situations, like tracking a plant's growth. They also sort shapes like rectangles, rhombuses, and squares by the properties they share.
Parentheses, brackets, and braces tell students which part of a math problem to solve first. Students practice reading and solving expressions that use these grouping symbols.
Students write math expressions like 2 x (8+7) to record a calculation in symbols, and read an expression to describe what it means without solving it. They can say "3 x (18932 + 921) is three times as large" without doing the arithmetic.
Students follow two different counting rules to build two number sequences, then look for a pattern connecting them. They pair up matching numbers from each sequence and plot those pairs as points on a grid.

Each position in a number is worth 10 times more than the spot to its right. So the 4 in 4,000 is worth ten times the 4 in 400.
Students figure out why multiplying by 10, 100, or 1,000 shifts digits to the left and dividing shifts them right. They also learn to write powers of 10 using exponents, like 10 with a small raised 3 meaning 1,000.
Reading and writing decimals like 3.047 or 12.568, then comparing which is larger or smaller. Students work with numbers that extend three places past the decimal point.
Students round decimal numbers to a chosen place, like the nearest tenth or whole number, and use that rounded value to make a reasonable estimate. The focus is on knowing which digit to look at and why.
Multiplying large numbers together, like 347 times 28, using a reliable method students can work through without a calculator. The focus is on getting the right answer efficiently, not just one way of doing it.
Students divide large numbers (up to four digits) by a two-digit number, using what they know about place value and multiplication to work through the problem in parts.
Students add, subtract, multiply, and divide numbers with decimal points, like $1.25 or $3.40. They use models or place-value thinking to work through the math, then explain in writing why their method works.

Students add and subtract fractions that have different bottom numbers, like 1/2 plus 1/3, by rewriting them so the bottom numbers match. They show their work using number lines or diagrams.
Students solve story problems that add or subtract fractions with different bottom numbers, like 1/2 plus 1/3. They also check whether their answer makes sense by comparing it to simple fractions they already know.
Students learn that a fraction is just a division problem written differently: 5 divided by 3 is the same as 5/3. They solve word problems where sharing whole numbers leads to fraction or mixed-number answers, then check whether the answer makes sense.
Multiplying a fraction by another fraction or a whole number. Students find a part of a part, like figuring out what half of three-quarters actually is, and practice doing it accurately across different kinds of problems.
Multiplying by a fraction smaller than 1 shrinks a number. Multiplying by a number larger than 1 grows it. Students predict whether an answer will be bigger or smaller than the starting number, just by looking at what they're multiplying by.
Students multiply fractions and mixed numbers to solve real problems, like finding the area of a room or scaling a recipe. They also check whether their answer makes sense before moving on.
Dividing a fraction like 1/2 by a whole number, or a whole number by a fraction like 1/3. Students use pictures and number sentences to show what happens when you split a fraction into equal parts or share a whole number into fractional pieces.

Volume measures how much space a solid shape takes up. Students learn to think of volume as layers of unit cubes packed inside a box or other 3-D shape, building toward measuring and calculating it.
Students count how many small cubes fit inside a 3-D shape to measure its volume. Those cubes can be standard sizes like cubic centimeters or cubic inches, or any same-size block that fills the space without gaps.
Students find the volume of boxes and other rectangular shapes by multiplying length, width, and height. They also break apart irregular shapes into smaller pieces, find each piece's volume, and add the results together.

Students learn to read and plot points on a grid using two numbers in parentheses, like (3, 4). The first number shows how far to move left or right, and the second shows how far to move up or down from the center.
Students plot points on a grid to show real-world data, like tracking distance over time, then explain what each point's location actually means in that situation.
A square is a rectangle because it has all the same properties, plus more. Students learn that shapes in a larger group share rules with every smaller group inside it.
Shapes can belong to more than one category at once. Students sort figures like squares, rectangles, and parallelograms by their properties, placing each shape inside a larger family it belongs to.

Students come up with a question they actually want to answer, such as whether taller kids tend to run faster. Then they refine that question until it can be answered by collecting and comparing real data.
Students learn how to gather data using tools like spreadsheets or apps, then figure out what to do when something looks wrong or a piece of information is missing.
Students look at charts, graphs, and tables to decide which ones clearly back up an answer to a question. They compare two or more displays and judge which one shows the data honestly and is easiest to understand.
Students look at data they collected, describe what it shows, and explain how two groups differ. They write a statement that answers the question their investigation set out to answer.

Students work with fractions in a serious way, including adding, subtracting, multiplying, and dividing them. They also learn decimals out to the thousandths place, multiply and divide larger numbers, and start graphing points on a coordinate grid. Volume of boxes and shapes shows up too.
Cooking is the easiest way in. Ask students to double a recipe that uses 3/4 cup or to figure out how much is left after using 1/2 of 2/3 of a bag. Talking through the answer matters more than getting it fast.
Fractions get harder this year, so frustration is normal. Slow down and draw pictures: a pizza cut into pieces, a rectangle split into strips, a number line between 0 and 1. Seeing the fraction usually unsticks the thinking.
Most teachers start with adding and subtracting unlike denominators, then move into multiplying fractions, then dividing with unit fractions. Decimals to the thousandths often sit alongside this work so place value stays fresh. Save volume and the coordinate plane for later in the year.
Dividing a whole number by a unit fraction and dividing a unit fraction by a whole number trip up most students. Multiplying a fraction by a fraction is also rough because the product gets smaller, which feels wrong. Plan extra time and visual models for both.
Yes. Multiplication and division facts get used constantly when finding common denominators, multiplying decimals, and dividing larger numbers. Five minutes of fact practice a few times a week keeps the harder work from stalling.
Volume is how much space fits inside a box or solid shape, measured in cubes. Students count unit cubes and then learn to multiply length by width by height. Stacking blocks or measuring a cereal box at home makes the idea click.
By spring, students should add, subtract, multiply, and divide fractions with confidence, work with decimals to the thousandths, and explain their reasoning with a model or equation. If those pieces are solid, ratios and early algebra next year will land much better.
Students learn to plot points using two numbers, like (3, 4), on a grid with an x-axis and a y-axis. They use it to graph patterns and answer real questions, such as tracking distance over time. Graph paper at home is a cheap way to practice.
