I work with students that range from year 1 to year 12, approx 30 with various Special Needs and esl. Because of the range in year levels and subjects covered it is impossible to find time to make my own resources for many of the lessons. Lesson Planet has become a realiable source to gain information and ideas.

For this divisibility rules worksheet, students review the rule and several examples for divisibility by 3. Students then complete 20 problems circling yes or no if the numbers are divisible by 3.
In this divisibility rules learning exercise, students review the rule for divisibility by 2 and then make a list of numbers from 20 to 50 that are divisible by 2. Students then mark an 'x' for the numbers that are divisible by 2. Students review the rule for divisibility by 5 and make a list of numbers between 40 and 100 that are divisible by 5. Students finish by completing the table determining if the numbers are divisible by 2 or 5.
In these divisibility rules worksheets, students memorize the divisibility rules for 2, 3, 4, 5, 6, 9, and 10 given in the chart. Students then use the rules to find the divisibility for the given numbers. Students circle the answers to the 15 numbers.
In this prime factorization and divisibility rules worksheet, students find the prime factorization for numbers and explore the divisibility rules for 2, 3, 4, 5, 6, ,9, and 10 in fifty-one problems. The solutions are not provided.
If your class has watched the Khan Academy video on recognizing divisibility, they will have a good foundation for this video on finding factors. Sal demonstrates how to find factors of a number by using the divisibility rules and systematically testing each number that could be a factor. This video is complete and clear and would complement a lesson nicely.
Rules of divisibility are presented in this excellent PowerPoint. There are 28 slides that give the divisibility rules from numbers one through eleven. Additionally, there are several interactive multiple choice questions for students to complete. There is also a 15-question assignment at the end of the PowerPoint Presentation. Very nice!
Ninth graders investigate divisibility rules. For 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 7, 11, and 13.
For this divisibility worksheet, students research the prices for 5 different computers then determine if each price is divisible by 2, 3, 4, 5 and 6. Students add a shipping charge of $22.75 to each price and then determine divisibility by 2, 3, 4, 5 and 6. Students reflect on using divisibility rules in their lives.
Use this decoding lesson in your special education class. With a SMART board file and worksheet, the lesson guides 6th graders through dividing two and three-syllable words using the Orton Gillingham syllable division rules (which are listed within the lesson plan). The lesson is designed for a class with a ratio of 6:1:1.
A great resource for any math teacher covering multiples, factors or square roots; this worksheet walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually increase in their level of difficulty and abstraction. Problem solving. multiple choice and word problems are intermixed with mathematical rules, definitions and fun facts to create a thorough and engaging activity. This worksheet also includes a brief extension section
