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.

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...

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...

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....

Give a voice to even the most quiet learners! Post discussion questions in different locations (on the whiteboard or around the room on posters). Class members then either answer a question posed or comment on a peer's response. Instead...

Students examine the trade network in Old Babylonia. They analyze maps, explore various websites, develop a list of goods imported to and exported from Babylonia, and write an essay.

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...

First graders analyze politics by participating in a class rules lesson. In this democracy lesson, 1st graders identify several class and school rules they dislike and conduct discussions to examine if they should be changed or not....

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 explore the concepts of laws and customs in a community, examining the reasoning behind rules. Then then collaborate to write their own classroom code of conduct.

Learners discover details about Mexican Revolution era artists. In this Mexican Revolution instructional activity, students research the events and people of the time period. Learners then research the artists of the time and create...

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

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

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

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

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.

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 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.

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.

Sixth graders create note cards to divide multi-digit whole numbers by two-digit numbers and divide decimals that represent money by whole numbers in a simpler and faster fashion. They write the rules and examples of each on the cards...

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