3rd Grade Math Worksheets

What the 3rd Grade math worksheets cover

3rd Grade practice brings multiplication and division forward: facts checked by multiplying back, two-digit by one-digit multiplication with an estimate first, and fractions built from strips. Place value now includes rounding, and measurement adds weight, capacity and elapsed time.

Each set is deep enough to practice the same skill many times without repeating a page, and every sheet can be marked from its own key.

These are practice pages, not the lesson. Building Number Sense is the sequenced K–5 math curriculum on this site; these worksheets are where a child gets the repetitions afterwards.

What the 3rd Grade sheets practice, set by set

• Number Lines: Halves, thirds and fourths placed on number lines, and a line plot in quarter inches.
• Number of the Day: A three-digit number as hundreds, tens and ones, in a number bond, one and ten more or less, even or odd, in words, in base-ten blocks and on a number line.
• Place Value: Numbers to the thousands in a place-value chart, expanded form, and rounding to the nearest ten and hundred.
• Addition with Regrouping: Three-digit addition with regrouping; the answers unlock a coded message, and the child explains it in two sentences.
• When Ones Make a Ten: Making a ten to add, then two-digit sums in a place-value chart and a story problem.
• Break Apart a Ten: Three-digit subtraction that borrows across a zero, set out in a hundreds, tens and ones chart.
• Subtraction with Regrouping: Four-digit subtraction with borrowing, each answer checked by adding back.
• Understanding Multiplication: Equal groups counted into a multiplication sentence, groups drawn to match one, and a story problem.
• Multi-Digit Multiplication: A two-digit number times one digit, with an estimate written first.
• Divide and Check: Division facts from the times tables, each checked with its multiplication fact, and one problem to draw as equal groups.
• Fractions: Fractions named on strips, compared, and matched to equivalent fractions up to eighths.
• Elapsed Time: The time between two clocks, to the minute and across the hour, counted out on a time line.
• Measurement Units: Kitchen scales and measuring jugs to read in grams, kilograms and liters, and a table of unit conversions to finish.
• Measurement: Length, time to the minute, and bills and coins with change from two dollars.
• Data: Tally marks to count into totals, a bar graph to draw from them, questions to read off it and three sentences to write.
• Line Graphs: A line graph to read, then six points to plot and join, on scales of one and two.
• Pictographs: Picture graphs with keys of five and ten, to read and then to draw from a table.
• Geometry: Perimeter and area from side lengths, and a rectangle to draw from a given perimeter or area.
• Polygons and Classifying Shapes: Polygons sorted by their sides and right angles, and always, sometimes or never statements about squares and rectangles.
• Skip Counting: Patterns in the hundreds, a function machine whose rule multiplies, and the odd one out.
• Find the Unknown: Multiplication and division fact families, with the missing number in any place.
• Fix the Mistake: Four worked problems, one in each operation, each with a mistake to find, fix and explain.
• Core Skills: All four operations in a quick review, then larger sums and differences worked out in boxes.
• Quarter Check: A scored check: rounding to the nearest ten, four-digit adding and subtracting, multiplying by one digit and division facts.
• Word Problems: Two-step stories that pair multiplying or dividing with adding or subtracting.
• Interactive & Puzzles: Multiplication and division facts matched to their answers, then a skip-counting path.
• Solve and Color: Two-digit sums and differences and multiplication and division facts; the answers color a design.
