Place value and decimals
Students extend place value into the decimals, reading and writing numbers down to the thousandths. They compare decimals, round them, and notice what happens when a number is multiplied or divided by ten.
This is the year math stretches into decimals and fractions as full working numbers. Students read and compare decimals to the thousandths place, then add, subtract, multiply, and divide them. Fractions with unlike denominators get added and subtracted, and students start multiplying and dividing fractions in real situations like recipes or sharing. By spring, they can find the volume of a box by multiplying length by width by height.
Students extend place value into the decimals, reading and writing numbers down to the thousandths. They compare decimals, round them, and notice what happens when a number is multiplied or divided by ten.
Students multiply large numbers using the standard method and divide with two-digit divisors. They also add, subtract, multiply, and divide decimals, explaining their thinking with drawings or written steps.
Students add and subtract fractions and mixed numbers with different denominators. They use equivalent fractions to rewrite the problem, then check whether the answer makes sense.
Students multiply fractions by whole numbers and by other fractions, often using a rectangle to picture the answer. They also start dividing with unit fractions, like sharing one-third of a pan of brownies among four people.
Students find the volume of boxes by counting unit cubes and using length times width times height. They also convert units within the same system, like inches to feet, and use line plots to answer questions about measurements.
Students plot points on a grid using ordered pairs and use the grid to solve real problems, like tracking a plant's growth over time. They also sort shapes by their properties, seeing how a square fits inside the family of rectangles.
Students write math phrases like (4 + 3) x 2 using parentheses and operations, then explain what those expressions mean in plain words. They don't solve for a final answer, just build and read the math sentence itself.
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 correctly.
Students write math expressions like (8 + 4) x 3 to show a calculation in shorthand, and read expressions to describe what they mean without solving them.
Students look at two number patterns side by side, find a rule for each one, and describe how the patterns relate to each other.
Students follow two number rules to build two separate sequences, then compare matching terms to spot a relationship. They plot those pairs as points on a grid.

Students learn how each position in a number is worth ten times the position to its right. They use that relationship to read, write, and compare numbers up to the billions and down to the thousandths.
Each spot in a number is worth 10 times more than the spot to its right. So the 4 in 400 is worth ten 40s, and ten times smaller than the 4 in 4,000.
Students learn why multiplying by 10, 100, or 1,000 shifts digits to the left and dividing shifts them to the right. They also practice writing those round numbers using exponents, like 10 to the third power instead of 1,000.
Students read and write decimal numbers down to the thousandths place, like 3.047, and compare two decimals to decide which is larger or smaller.
Students read and write decimal numbers like 347.392 in three ways: as a standard number, in words, and broken into each digit's value (3 hundreds + 4 tens + 7 ones + 3 tenths, and so on).
Students compare two decimal numbers out to the thousandths place and write which is greater, lesser, or equal using the symbols >, <, and =. The comparison is based on what each digit's position actually means.
Students round decimal numbers to a chosen place, like the nearest tenth or hundredth. They use what they know about place value to decide whether to round up or down.
Students add, subtract, multiply, and divide large whole numbers and decimals like $3.75 or 12.50. The work builds the number sense students need before algebra.
Students multiply large whole numbers the way most adults learned in school, stacking the numbers and working through each digit step by step, without needing a calculator.
Students divide large numbers (up to four digits) by a two-digit number and show how they got the answer using a drawing, a grid, or an equation. The work makes the reasoning visible, not just the result.
Students add, subtract, multiply, and divide decimal numbers like 3.75 or 12.4, then explain in writing why their method works. They use place value and sketches or models to show their thinking.

Students practice switching between units in the same system, like turning centimeters into meters or pounds into ounces, then use those conversions to solve real-world problems with more than one step.
Students read and build graphs and line plots using data that includes fractions. They answer questions about what the data shows, like finding differences or totals between values.
Students collect measurements in fractions, plot them on a number line, then use that chart to answer questions by adding or subtracting the fractional values shown.
Students learn what volume means and practice measuring it. They connect volume to multiplication and addition by figuring out how many unit cubes fill a box or other solid shape.
Volume measures how much space a three-dimensional solid takes up. Students learn to think of volume as the number of small unit cubes that fit inside a box or other solid shape.
A unit cube is a perfect cube with sides 1 unit long. Students use it as the basic building block for measuring volume, the same way they use a single square to measure area.
Students learn that volume is just a count of how many small cubes fit inside a 3-D shape, with no gaps and no overlaps. If 24 cubes fill a box, the box has a volume of 24 cubic units.
Students count the small cubes packed inside a 3-D shape to find its volume. They use standard cubes measured in centimeters, inches, or feet, and sometimes cubes of other sizes.

Students plot points on a grid using two numbers, one for how far across and one for how far up. They use that skill to read maps, track data, and solve math problems.
Students learn to plot points on a grid using two numbers, like (3, 5). The first number shows how far to move across, the second shows how far to move up.
Students plot points on a grid to show real-world information, like distance traveled over time, then explain what the location of each point means in that situation.
Students sort flat shapes like squares, rectangles, and triangles into groups by looking at their sides, angles, and corners. A square counts as a rectangle because it shares the same properties.
Shapes that belong to a group share every rule of that group. A square follows all the rules for rectangles, which follow all the rules for parallelograms, and so on up the ladder.
Shapes can belong to more than one category at once. Students sort figures like squares, rectangles, and rhombuses by their properties, learning that a square is also a rectangle, and a rectangle is also a parallelogram.

Students add and subtract fractions with different denominators by first converting them to a common denominator. Think of it as cutting two different-sized slices into equal pieces so they can be compared and combined.
Adding fractions is straightforward when the bottom numbers match. Students learn to rewrite fractions so they share a common bottom number, then add or subtract, including problems that mix whole numbers and fractions.
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 a familiar fraction like 1/2 or 1.
Students use what they already know about multiplication and division to work with fractions, including multiplying a fraction by a whole number or another fraction and dividing fractions into equal parts.
A fraction is just a division problem written in a different form. Students learn that 3/4 means 3 divided by 4, then use that idea to solve word problems where the answer comes out as a fraction or mixed number.
Multiplying a fraction by another fraction or a whole number. Students learn that taking a fraction "of" something, like 2/3 of 4, is the same as multiplying, and they find the result using area models or number lines.
Multiplying a fraction by a whole number means splitting that whole number into equal groups and taking only some of them. For example, 2/3 of 12 means dividing 12 into 3 equal groups, then counting 2 of those groups.
Students find the area of a rectangle whose sides are fractions by multiplying those two fractions together. They also check that answer by filling the rectangle with small equal squares and counting them up.
Multiplying a number doesn't always mean getting something bigger. Students learn to predict whether a product will be larger or smaller than the starting number based on what they're multiplying by.
Multiplying a number by a fraction less than 1 makes the result smaller than what you started with. Students figure this out by looking at the fraction, not by doing the full calculation.
Multiplying by a fraction bigger than 1 makes a number grow; multiplying by a fraction smaller than 1 makes it shrink. Students explain why this happens, not just accept it as a rule.

Dividing a fraction like 1/2 by a whole number, or a whole number by a fraction like 1/3, and finding what that answer means. Students use drawings or number lines to show why the math works.
Dividing a fraction by a whole number means splitting that fraction into even smaller pieces. Students figure out, for example, how much of a pizza each person gets when one-third is shared among four people.
Dividing a whole number by a fraction means figuring out how many fraction-sized pieces fit into it. Students solve problems like "how many one-third pieces fit in 4?" and calculate the exact answer.
Students use drawings and equations to solve everyday problems that involve dividing a fraction by a whole number or a whole number by a fraction, such as splitting half a pizza among 3 people or finding how many quarter-miles fit in 3 miles.

Students should add, subtract, multiply, and divide fractions, multiply large whole numbers, and work with decimals out to the thousandths place. They should also find the volume of a box, plot points on a grid, and solve word problems that take more than one step.
Cooking is the easiest way in. Halving a recipe, doubling it, or asking how many quarter cups fit in two cups gives real practice with adding, multiplying, and dividing fractions. Ten minutes in the kitchen beats a worksheet.
Use money and a ruler. Ask what 0.1, 0.01, and 0.001 of a dollar would be, or compare 0.4 and 0.40 on a ruler. Seeing that the place to the right is ten times smaller makes the rules feel less random.
A common path is place value and decimals first, then fraction addition and subtraction, then fraction multiplication and division, then volume and the coordinate plane. Saving fraction division for later in the year gives students more time with fraction meaning before the trickiest operation.
Fraction division and decimal place value are the two big ones. Students often memorize a rule without a picture, then forget it by spring. Plan extra time for visual models with both, and revisit them in warm-ups all year.
Yes. The standard algorithm for multi-digit multiplication and long division both fall apart when basic facts are shaky. Five minutes of fact practice a few nights a week pays off in every other topic this year.
Students should find the volume of a rectangular box using length times width times height, explain why that works by picturing unit cubes inside, and add the volumes of two boxes stuck together. Word problems about fish tanks or moving boxes are a good check.
They can solve a multi-step word problem with fractions or decimals and explain their reasoning, not just the answer. They can also plot points on a grid and compare decimals out to the thousandths without guessing.
Students learn to plot points in the first quadrant and read what those points mean in a real situation, like time and distance on a walk. At home, graph paper and a simple table of values is enough to practice.
