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...

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...

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,...

Rules are meant to be broken ... but not integer multiplication and division rules. Learners use chips to model integer multiplication and division. The results of the activity help them develop integer rules for these operations.

Partners create integer multiplication word problems and swap them to solve, followed by altering the problem to use rational numbers. By working with word problems involving multiplication and division of rational numbers, pupils...

Encourage at-home assistance with a reference sheet designed to provide parents and guardians with the information they need to help their child divide fractions. Three pages offer detailed descriptions and labeled examples.    

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...

The 12th segment in a 25-segment series looks at the division of integers and how the signs of the dividend and divisor affect the sign of the quotient. Pupils start with multiplication and division facts of whole numbers and create the...

Eliminate young mathematicians' confusion over performing operations with integers using this set of classroom displays. Providing learners with simple, easy-to-follow rules, this resource will have students fluently adding,...

Create a human fraction to learn about division of exponents. Scholars develop the rule for division of exponents by being part of a human fraction to explore and justify the rule. They also consider zero exponents and negative exponents.

Are exponent rules different if the exponents are negative? Using the definition of negative exponents and the rules of exponents, the resource shows that the rules of exponents hold independent of the sign of the exponent. Practice...

Make the complicated look relatively simple. The video shows how multiplication of algebraic fractions is easier when they factor the numerators and denominators. Pupils see which factors will cancel, or divide out, easier when writing...

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...

Ours is to wonder why, not just to invert and multiply. The seventh installment of a 21-part module uses fraction models to help pupils understand why the invert-and-multiply strategy for dividing fractions works. They then work on some...

It just multiplies out. The lesson provides the rules for operations with exponents and keeps them as positive integers in the lesson. Videos explain the rules for the operations with exponents while working out examples. 

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...

There's nothing negative about this mini-unit on integers! Engaging young mathematicians in a series of hands-on activities and collaborative learning opportunities, this resource offers an excellent way to introduce your class...

Young mathematicians construct their own understanding of integers with an inquiry-based math instructional activity. Using colored chips to represent positive and negative numbers, children model a series of addition and...

It's the classic please excuse my dear aunt sally strategy to remembering the order of operations. Young mathematicians practice to develop an understanding of the order of operations. Examples and practice problems include...

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,...

What assumptions are made in order to solve equations? An instructional slideshow provides an overview and guided examples of how properties of equality can be used to justify each step in solving equations.
