Master 3rd Grade Math

Master number sense by learning place value, ordering numbers, and rounding and estimating, with expanded form and word form, plus video tutorials, quizzes, and a final exam.

Master 3rd grade math unit 1 place value features five tutorials, including an introduction, place value chart, finding value with fill-ins, reading numbers, with practice problems and a final quiz.

Learn to read large numbers by place value, identify digits in the billions, millions, thousands, and hundreds places, and locate ten thousands, ten millions, and hundred millions positions.

Identify missing place values in a place-value chart from billions to ones. Practice by filling blanks in your notebook and verifying with the original PDA printouts.

Practice reading numbers aloud, left to right, using the pause button to check your understanding and prepare for the upcoming quiz.

Learn to compare two numbers by lining up digits in a place-value chart and using the leftmost differing digit to decide which is bigger, across thousands, hundreds, tens, and ones.

Master two methods in unit 3 to convert numbers into expanded form and word form using a place value chart, with graph paper no longer needed.

Learn how to convert numbers into word form by naming each three-digit group: hundreds, thousands, millions, and billions, and write the number exactly as it sounds with correct commas.

Apply the rules to round two-digit numbers by underlining the tens place, circling the units digit, and setting digits to the right to zero, as shown with 37 to 40.

Master 3rd grade math teaches rounding numbers by underlining the target digit, circling the next digit, applying the 5 or greater rule, and turning digits to the right to zero.

Estimate by rounding to the biggest place value and solving, then apply to subtraction, addition, multiplication, and division.

Learn to add three or more numbers using two methods, carry from ones to tens and hundreds, and practice with problems to verify results.

Master 3rd grade math teaches you to subtract three digit numbers with regrouping, including borrowing from tens and hundreds and handling multiple regroupings, with guided practice via the PTF below.

Master subtraction with zeros by borrowing across hundreds, tens, and ones, using step-by-step examples and practice problems to build lifelong fluency.

Learn to subtract several numbers using two methods: subtract one by one or add the subtrahends first, with examples like 55-24-16 and 347-141-96.

Learn to find area by counting squares inside shapes, with examples yielding 12 and 9, and practice on two rectangles while learning a quick trick for large shapes.

Learn to find the area of irregular shapes by cutting into rectangles, counting squares, and adding areas; the lesson also introduces a subtraction method.

Compare two methods to find area when removing a piece of a shape, using subtraction of rectangle areas or rearranging shapes to count the remaining area.

In unit 4, learn three strategies to find the perimeter, contrasting it with area—the amount of stuff inside an object—and apply methods for each concept.

Find the perimeter of rectangles by counting around the shape or by adding two different sides and doubling the sum. Use the two equal sides concept and doubling to verify.

Calculate the perimeter of various shapes by adding all sides, from triangles to rambis and a house-shaped figure, and mark used sides to avoid double counting.

Practice chapter 2 video practice test to master adding and subtracting with regrouping and borrowing, and reinforce area and perimeter concepts.

Explore multiplication and division through units on multiplication facts, hundreds, division facts, and fractions. Each unit includes a quiz and a video practice test to prepare for the final exam.

Master 3rd grade math emphasizes mastering multiplication facts, teaching four ways to learn them—flashcards, practice tests by repeated writing, and a hands-on method—to build a strong math foundation early.

Use inexpensive flashcards to build math fact fluency by practicing each multiplication level from 1 to 10, then twos, removing mastered cards as pace improves, week by week.

Repeated writing helps students practice multiplication facts by writing equations like three times four equals twelve repeatedly, even if it's the only effective method for some learners.

Explore the hands-on method with songs and a friendship bracelet activity to teach multiplication, showing three times four equals twelve through four rows of three for memorable recall.

Practice multiplying by tens, hundreds, and thousands to strengthen grade 3 multiplication skills, preparing you for multiplying by hundreds in this unit.

Learn to multiply by hundreds using grouping, converting to repeated addition, and adding zeros to the product as you scale from 12 to 120, 1200, and 12000.

Learn how to multiply by hundreds using the standard algorithm, with place-value alignment and carry steps, plus practice problems like 40×3, 400×3, and 60×5.

Practice division by grouping objects with a hands-on method, splitting 20 blocks into 2 or 4 groups, and exploring remainder to solidify understanding.

Learn division facts with flashcards, starting by practicing with twos and fives, then threes, fours, sixes, and sevens, plus four learning methods including fact families and practice tests.

Master division facts through weekly practice tests and flashcards, with two weekly tests, two final tests, and parent-created exercises using the right numbers.

Explore how fractions work, what fractions are and how they look, then learn to create your own fractions and determine when fractions are equal in the third grade.

Explore fractions with examples like one half, two thirds, and three fourths. Learn that the numerator is the top part and the denominator the bottom part of a whole.

Turn pictures into fractions and back by counting shaded parts to identify numerators and denominators. Practice with squares and circles and convert examples like two fourths and five eighths.

Create number lines for fractions by drawing an arrow, adding zero, numbering marks to the denominator, converting to fractions, and marking the example fraction such as three fourths.

Explore using number lines to add and subtract fractions, visualizing distances on fractions like eighths and sevenths, and solving word problems by counting steps from a starting point.

Explore two types of patterns in third grade: number patterns and object patterns. Learn how objects repeat and how to identify math patterns in numbers.

Identify the math rules behind number patterns, apply plus two and minus five sequences, and practice solving for missing numbers in varied patterns.

Create a clock and learn to tell time, exploring how to move into the future and go into the past with time traveling as a fun, practical math lesson.

Master 3rd grade math teaches students to tell time by reading the hour hand between numbers and the minute hand counting by fives, with practice problems and clock diagrams.

Practice time-telling and adding minutes to future times using a clock or math, understanding hour changes when the minute hand crosses 12, with problems on arriving home and completing it.

Explore pictographs by using a key, counting cans, and interpreting a triangle-based pictograph where triangles equal five points in a 100-point game to find Caylee’s score.

Guide learners through the 2018 New York State third grade math exam walk-through, solving problems on multiplication, rounding, fractions, measurement, time, and area.
