# 4th Grade Common Core: 4.OA.4

Common Core Identifier: 4.OA.4 / Grade: 4
Curriculum: Operations And Algebraic Thinking: Gain Familiarity With Factors And Multiples.
Detail: Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.

Introduction to finding prime and composite numbers
On these M.B. worksheets, students will differentiate between prime and composite numbers, calculate measurements of adjacent angles, convert standard measurements, and subtract fractions with unlike denominators.
This file contains 15 least common multiple activity cards. Use them for learning centers, peer review, exit slips, classroom scavenger hunts, or on your Smartboard's document camera.
Use the Sieve of Eratosthenes to find prime numbers. The sieve is simply a hundreds chart. Students check off multiples of 2, 3, 5, and 7. Every number that is not checked off is a prime number.
Review number patterns, pounds to ounces conversions, angle types, fractions on a number line, division with remainders, and equivalent fractions.
Sort factors of numbers on Venn diagrams.
More review of 2-digit by 1-digit multiplication, multi-step story problems, acute/right/obtuse angles, subtraction across zero, and liter/milliliter conversions.
In the tenth week of Math Buzz, students will use order of operations to evaluate expressions, calculate .1 and 10x a given number, find the volume of a cube, and subtract mixed numbers with unlike denominators.
This file contains 15 task cards for reviewing Greatest Common Factor. Use these cards for peer review, classroom scavenger hunts, exit slips, or learning centers.
This 120 chart highlights prime numbers in orange.
Challenge your 4th graders to solve math problems related to: multi-step word problems, decomposing fractions, prime and composite numbers, seconds to minutes conversions, and geometry.
This is similar to the other Venn diagram worksheet except it includes more complex versions of Venn diagrams.
Color the prime numbers red and the composite numbers blue.
In this set, we have more word problems, symmetry challenges, comparing fractions, part-part-whole models, acute/right/obtuse angle identification, factor pairs, and a line plot.
On these five printable daily review worksheets, students will practice calculating greatest common factor (GCF), expressing decimal numbers in expanded form, solving word problems classifying triangles (acute/right/obtuse and isosceles/scalene/equilateral), and operations with decimals.
On this Carroll diagram, students sort numbers by odd and even. The also sort by: multiples of 3, multiples of 5, and multiples of 7.
In the seventh set, students will solve input and output tables, practice rounding, geometry, comparing numbers, perimeter, and much more.
On these printable worksheets, your fifth graders will review parallel/intersecting/perpendicular lines, long division (without remainders), estimating basic operations, factors, area models, and word problems.
On this printable, students will list multiples of numbers. Then there are two short answer questions.
Part 1: List the first five multiples of the given numbers. Part 2: Circle the multiples of the given number.
This file contains the next 5 days of 4th grade math review. Problems assess the following skills: number patterns, fractions on a number line, 3-digit by 1-digit multiplication, prime/composite numbers, inches to feet conversions, and more.
Place the numbers in the correct place on the Venn diagrams. (For example: There's a Venn diagram with "Multiples of 3" and "Multiples of 2." Students place the given numbers in the correct place on the Venn.)
This set has more perimeter, area, and volume problems. There are also a few problems on multiplying and dividing fractions. Students will complete a factor tree. Each worksheet also has a word problem to solve.
In this file for Math Buzz, Week 8, your students will review standard form and expanded form, place value, input and output tables, area, geometry, and rounding.
Draw an angle with a protractor, add three fractions together and simplify, solve word problems, rewrite phrases as algebraic expressions, convert mixed numbers to fractions, tell whether numbers are prime or composite, and solve long division problems with 4-digit dividends.
