The lesson plan starts out with a brain drain, which is a great way to get students to activate prior knowledge and build lasting connections. They tell everything they know about prime factorization, use their knowledge to...

How many prime numbers are there between 1 and 100? By using a prime time resource, your scholars should be able to answer this question. Using arrays, they determine if numbers are prime or composite, and then write a prime...

Show the class how to find the factors of numbers. They use a variety of strategies, including unifix cubes, to find the factors of a whole number. This resource includes clear procedure to follow. Included are an anticipatory set,...

Students work with prime numbers. In this prime factorization lesson, students review writing numbers in their prime factorization form and solve multiple problems.

Explore prime numbers. Learners use an interactive 100's chart to identify prime numbers, discuss a glossary of terms, use cards to list multiples of 2,3,4,5, and play a bingo game.

Sixth graders participate in a lesson that focuses on the concept of finding the prime factorization of a number. They write the answer using exponential notation. Students play a game of Bingo to keep engaged during the lesson.

Students research prime and composite numbers. With a partner, students use graph paper to draw rectangles of various sizes. They list the dimensions of rectangles and discuss how the dimensions relate to the factors of each number....

Young scholars explore the concept of prime factorization. In this prime factorization activity, students participate in an activity where they find the prime factorization and greatest common factor of a number derived from their name....

Learners create factor trees.  In this prime and composite lesson, students model fractions using tiles.  They create factor trees and identify prime and composite numbers.  Learners use grid paper and tiles to model...

Fifth and sixth graders explore prime numbers. They work with a partner to build rectangular arrays using twelve tiles. Factor pairs are noted and recorded on graph paper. Pupils construct rectangular arrays with a prime number and...

Seventh graders practice determining the prime factorization of composite numbers. They create Christmas factor trees for prime numbers greater than 100. They decorate their final products with markers, crayons, colored pencils, glitter...

Upper graders study fraction and mixed number division and also review fraction multiplication. In this fraction and mixed numbers instructional activity, learners work with the teacher in an oral problem solving method to multiply and...

Sixth graders use the prime factorization of numbers to find the greatest common factor and least common multiple. Working in small groups, they solve problems using the greatest common factor and least common multiple.

Young mathematicians discover trees organize more than just families — they help factor, too. The lesson begins with factor trees and develops slowly to factoring by grouping and special patterns. 

Prime and composite numbers are the focus of this mathematics lesson. In it, learners practice techniques for identifying these two types of numbers. They utilize the Inspiration program to complete a task that is clearly explained, and...

Pupils identify numbers as prime or composite and complete prime factorization of composite numbers.

Solving factor trees is a helpful way to introduce prime numbers. Your math class practices using this method along with two-column tables to find if a number is prime or not. They also learn other vocabulary, such as composite numbers,...

Uncover the relationship between factoring quadratics and higher degree polynomials. Learners develop their factoring skills through repetition. A comprehensive lesson begins with quadratics and shows how to use the same patterns to...

Fifth graders use prime factorization to identify prime and composite numbers. They use cubes to find factors. In groups, 5th graders draw rectangular arrays to discover prime numbers under 100.

Fifth graders review the concept of prime factorization. Then, they use the rules for divisibility and other notions to find the prime factorization of unfamiliar numbers. They solve problems in a whole class setting.

Young scholars use Venn diagrams to solve prime number and factorization problems. In this multiplication lesson, students watch a video and use a Venn Diagram to help them solve a pizza math activity that uses prime factorization. Young...

Students recognize the difference between a prime and a composite number.  For this prime and composite number lesson, students  use a factor tree model to show prime factorization. Students participate in a bingo activity....

Fourth graders investigate the concept of prime and composite numbers. Students study the visual representation for the numbers and use the pictures in order to develop designs for larger numbers. The goal of the activity is for them to...

Create Venn diagrams. Your class will discover the relationships between even and prime numbers. Next, they will compare that to the relationship between odd and composite numbers.
