Number patterns help your kids learn divisibility and estimation rules. This activity aims to strengthen their math fact memorization skills by presenting several rules they are expected to memorize through practice.

Who knew the sum of a number's digits gives such interesting information? The 18th installment of a 21-part module has scholars investigate division by three and nine. After looking at several examples, they develop divisibility tests...

How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...

Learners examine the concept of finding the greatest common factor. They complete number of activities as they practice identifying prime and composite numbers. Pupils apply rules of divisibility and find the greatest common factor while...

Sixth graders strengthen their knowledge of the divisibility rules. Students access that mental math can be faster than the calculator for certain types of problems. Students can make generalizations and discover patterns in finding the...

Students inspect divisibility rules. For this divisibility rules lesson, students study the relationship between factorization and the divisibility rules for 2, 3, 5, 6, 9, and 10. Students read One Hundred Hungry Ants and A Remainder of...

Students discover the Sieve of Erathosthenes. They explore a method to find all the prime numbers in a group of numbers. Using models, students practice divisibility rules while examining the difference between prime and composite numbers.

Young learners apply divisibility rules to determine if a number is a factor of another number. They discuss what numbers are factors of another number and identify patterns using divisibility rules.

Sixth graders participate in a lesson that covers the Rules of Divisibility. They play a game for a warm-up before the direct instruction. Following the rules being covered they finish the lesson using an assignment included in the...

In this mathematics worksheet, 4th graders write the divisibility rule for each factor given. Then they practice the rules by dividing the numbers listed by each factor and place a check mark in the box if it is a factor of the number.

In this math worksheet, learners are given a reminder of what divisibility means. Students then answer 10 divisibility questions.

Students explore the concept of divisibility. In this divisibility lesson plan, students determine which numbers are divisible by another number.

For this math worksheet, middle schoolers examine the 20 numbers in order to test their divisibility. The rules of divisibility are given at the top of the page.

In this divisibility rules worksheet, students solve problems using the division rule for the number three. Examples and explanations are given prior to the exercise. This one-page worksheet contains approximately 20 problems.

Young scholars play Divisibility Buzz to reinforce divisibility rule for three.

Students examine the rules of divisibility for the numbers 2, 3, 5, 6, 9 and 10. They apply these rules to larger numbers.

Students become familiar with the importance of money now and the forms of money used in the past.  In this money lesson plan, students investigate the cour characteristics of money: portable, divisible, durable and...

Students become familiar with divisibility rules as they view a fun PowerPoint Presentation. Within this instructional activity, students are provided with a worksheet that explains the divisibility rules. Finally, students are given...

Ninth graders investigate divisibility rules.  In this middle school mathematics/Algebra I lesson, 9th graders explore the divisibility rules of 7, 11, and 13.  Students examine certain six-digit numbers that are divisible by...

Use the 20 Questions game to practice math vocabulary and number properties! Project a hundreds chart and hand one out to learners. Ideally, give them counters (beans would work well) to mark off the chart so you can play multiple times....

Sixth graders explore how to apply the commutative property and the rules of divisibility. They examine the difference between prime and composite numbers.

In this math worksheet, learners evaluate 15 expressions using the order of operations. Students then evaluate 4 more expressions with given numerical values for variables.

Patterns in math emerge from seemingly random places. Learners explore the patterns for factoring the sum and differences of perfect roots. Analyzing these patterns helps young mathematicians develop the polynomial identities.

Seventh graders practice applying the rules of divisibility.
