Factors and Multiples Worksheets for 4th Grade
Find factors and multiples of numbers and identify prime and composite.
About Factors and Multiples
Place value is the idea that a digit's value depends on its position within a number. The "3" in 30 is worth ten times more than the "3" in 3. This concept is the backbone of our entire number system and is essential for understanding how multi-digit numbers work.
Factors and multiples are the building blocks of number theory and essential for fraction work. Recognizing factor pairs makes simplifying fractions and finding common denominators much more efficient.

Tips for Parents & Teachers
Use physical bundles: group 10 pennies, straws, or blocks together and call them "one ten." Then show 3 tens and 4 ones to represent 34.
Play "build the number" — say a number and have your child show it with tens and ones using objects or drawings.
When your child sees a two-digit number, ask: "How many tens? How many ones?" until it becomes automatic.
Connect to money: a dime is worth 10 pennies, which is a perfect real-world model of tens and ones.
