Learning division is a challenge for many young mathematicians, but this presentation on divisibility rules can make it much easier. Seven different rules are clearly explained and modeled with the support of multiple examples. Consider...

There's a lot to remember when it comes to math concepts. Help scholars get a head-start to learning division with a reference page offering divisibility rules for the numbers two, three, four, five, six, eight, nine, and 10. 

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...

Proofs do not exist only in geometry. The video shows the class different ways that proofs appear in algebra. Pupils work through a variety of algebraic proofs involving the divisibility of an algebraic expression or whether it is even...

Prime or composite, that is the question. Teach your class how to find the answer with this step-by-step presentation that defines and provides examples of each type of number. When addressing larger numbers, divisibility rules are...

RJ had an awesome basketball season this year! Use division by double-digit numbers to calculate his scoring average in this instructional presentation. Starting with an explanation of the terms dividend, divisor,...

Take your class on a field trip to Fractalland where they'll learn all about number and shape patterns. Based on Disney's movie Alice in Wonderland, this resource takes young mathematicians on an adventure as they explore patterns in...

Give the class a prime example of using prime numbers. After reviewing prime factorization of numbers with the video, pupils use their knowledge to determine greatest common factors and least common multiples in the worksheet. The...

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.

Learning the algorithm for long division is no easy task, but this resource helps to break the process into manageable steps. Beginning with an explanation of basic division vocabulary, this presentation goes on to model long division...

Your fifth graders will appreciate the simple, direct explanations, examples, and practice exercises in this well-organized unit on fractions. Beginning with an introduction to fractions, the packet flows smoothly through the fraction...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Ready, set, go! Individuals practice converting rational numbers between fractions, decimals, and percents. A speed game has teams match the three forms of rational numbers on a number line.
