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...

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...

It's not a short cut, just good old fashion number sense, but kids will love it. This presentation does a wonderful job describing the divisibility rules by showing how each one works, reviewing the rules as a collective and providing an...

Students inspect divisibility rules. In 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...

In this math instructional activity, students learn the divisibility rule for 9s-- if the sum of the digits in the dividend is a multiple of 9, there will be no remainder in the quotient. Students complete 27 division problems with a 4...

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...

In this division instructional activity, students find the divisibility of whole numbers. Students fill-in a chart of numbers indicating whether they are divisible by other numbers.

In this independent events probability worksheet, students solve 10 different problems that include determining the probability of certain events described. First, they determine the probability of selecting at random a number divisible...

In this divisibility rules worksheet, learners solve 18 different problems that include applying the divisibility rules to each. First, they identify the hypothesis and conclusion in logical deduction. Then, students determine 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.

Students play Divisibility Buzz to reinforce divisibility rule for three.

Seventh graders explore the concept of divisibility. In this divisibility lesson plan, 7th graders use divisibility rules to find factors of numbers. Students create foldables to illustrate divisibility rules.

Use Glencoe's randomly generated self-checking quiz to test your knowledge of divisibility patterns. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check It"...

A handy table of the rules of division is presented here. Examples are given for each of the rules, from the number 2 to the number 10. The site stresses that a list such as this isn't cheating, but rather a nice resource to have.
