Easy Math for 3rd Grade

Learn to identify predecessors and successors by finding one less or one more, using number lines, and applying greater, smaller, more, and less.

Learn to compare two-digit numbers using greater than, less than, and equal to signs, focusing on tens and units, with number line insights and practical examples.

Explore table 100, a grid of the first 100 numbers arranged by tens and units, and learn to find missing numbers, identify ten groups, and practice number patterns.

Explore numbers up to 1000 by identifying three-digit numbers and decoding hundreds, tens, and units through place value charts, accounting frames, and graphical representations.

Identify the place value of digits in three-digit numbers. Write numbers as a sum of hundreds, tens, and units, and show them on a counting frame and place value chart.

Master comparing three-digit numbers by using place value, applying greater than, less than, and equal to signs, and following hundreds, tens, and ones rules with practice problems.

practice time-bound place-value tasks with three-digit numbers, including identifying smallest and largest three-digit numbers, odd and even numbers, decompositions, expanded form, and calculating predecessors and successors on a number line.

Practice self-checking place-value tasks by decomposing numbers into hundreds, tens, and ones, reading a tenths number line, and sorting numbers, with examples like 753, 316, 144, and 358.

Learn to round numbers to the nearest ten, hundred, or thousand using digits in ones, tens, and hundreds. Apply rules with examples and a number line.

Learn to add a one-digit number to a two-digit number by adding to a full ten, using 46 plus 4 as a guided example and applying place-value strategies.

Learn to add a two-digit number with a full ten by adding the ones digit to the ten, using place-value and tens-ones breakdown with examples like 33 plus 50.

Learn to subtract a two-digit number from another by breaking into tens and ones and borrowing when needed, with examples like 90 minus 23 and 70 minus 48.

master adding a three-digit number to a one-digit number using place value charts, decomposition into hundreds, tens, and ones, and carrying when ones sum to more than ten.

Explore subtracting a one-digit number from a three-digit number using decomposition into hundreds, tens, and ones, with borrowing and place value charts, vertical, and column methods.

Learn to add a three-digit number and a two-digit number by decomposing into hundreds, tens, and ones, and using place-value charts, horizontal, and column methods.

Master doubling and half by multiplying by two and dividing by two, with practical examples like apples, pages, and butterflies to show two times more or less.

Master multiplication by one and by zero, showing that any number multiplied by one remains the same and any number multiplied by zero equals zero, guided by the commutative property.

Master multiplication by three through skip counting, the three times table, and multiples, while recognizing product, factors, and the commutative property.

Learn to multiply and divide by ten, add or remove a zero, understand ten times and one tenth, and apply the order of operations.

Learn multiplication and division by six, practice the six times table, and solve word problems such as six eggs for each grandchild and six cookies per child.

Master multiplication and division by eight, learn commutative properties, explore eight's multiples and related word problems, and apply order of operations for practical calculations.

Explore multiplying and dividing by nine, learn the nine times table, commutative property, and digit patterns in tens and ones, with tricks and word problems.

Learn how a straight line extends infinitely and how points relate to it. Through two different points, one line forms; collinear and non collinear points describe arrangements.

Explore how a point on a line creates two rays, define rays as half-lines starting at a point and extending forever, and learn naming conventions like ap1 and ap2.

Practice identifying whether points belong to lines and drawing lines through points. Explore collinear versus non-collinear points and the infinite nature of lines.

Learn what makes an angle from two rays with a common endpoint, identify the vertex and sides, and name angles with three-letter notation or Greek letters.

Learn to identify straight angles at 180 degrees, right angles at 90 degrees, and acute and obtuse angles from 0–89 and 91–179 degrees.

Learn to measure angles using a protractor, identify the vertex and baseline, read degree measures on both scales, and recognize right angles as 90 degrees.

Learn to color fractions by dividing a whole into equal parts and using numerator and denominator to show how many parts to shade, with examples like 3/5 and 1/3.
