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...

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 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...

Students play Divisibility Buzz to reinforce divisibility rule for three.

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 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 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...

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

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...

Students research the role played and contributions made by African American soldiers during World War I. They discuss the evolution of civil rights in America's history, and the progress that has been made in the last 100 years.

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...

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.

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...

This presentation is short and sweet! Seven concise slides detail the confusing punctuation mark and offer several examples. Bonus: Common mistakes and possible ways to correct those mistakes are also highlighted (like using a colon...

Students study the attributes of the 8 realms of Hawaiian vegetation. In this Hawaiian vegetation lesson, students read project cards to determine the elevation, rainfall, and organisms that live in each realm. They make a poster that...

For this global studies worksheet, students read the noted pages in their textbooks and then respond to 12 short answer questions about World War II, the Cold War, and economic divisions.

Students utilize an online database to conduct research and analyze the conditions for African-Americans before and after World War I. They consider the role of the 92nd and 93rd divisions in affecting social change.

Scholars learn how to write number theory proofs by viewing a video reviewing techniques for proofs on divisibility, parity, and consecutive integers. They then write proofs for a handful of conjectures on a worksheet.

Make fractions easier with a visual representation along a number line. There are eight fractions here for scholars to match to their corresponding number lines. Although this is a good idea, the formatting isn't ideal. Ask kids to...

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