What does baking cupcakes have to do with multiplication? Watch this video and find out as your class learns that multiplication is the repeated addition of equal groups. Properties of multiplication are also introduced with...

Zoe from the StudyJams! crew brings the properties of addition to life by clearly explaining the meaning of the associative, commutative, and identity properties as she collects photos for an album. Listen to the included karaoke song...

Help your class discover the commutative property of addition with this exploration of the addition table. By folding and coloring the table, a symmetry is found that directs learners to an understanding of this crucial mathematical...

Given different parallelograms, geometers make conjectures about their properties. They then work in small groups to prove (or disprove) their conjectures. The activity provides many opportunities for making conjectures and critiquing...

Preteens create a foldable in order to review the properties of operations. They apply their knowledge to write equivalent equations using stock market scenarios. A neat homework page is provided that has four expressions to be...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps - though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

The beginning of a new set of SAT practice problems from The Official SAT Study Guide involves sequences, distribution, combinations, and geometric figures. Sal makes sure to provide thorough explanations to each problem, while...

Fact families are an excellent way to connect math operations for beginners to addition and subtraction. Use the examples here to review this concept before scholars try these on their own. For each, they examine two related number...

Addition becomes much simpler once scholars understand its properties. They examine the commutative property through five equation pairs. For each, the addends have been switched and scholars must fill one in. The next six problems give...

Paper folding, flu spreading in a school, bacteria growth, and continuously compounded interest all provide excellent models to study exponential functions. This is a comprehensive resource that looks at many different aspects of these...

Some polynomials, when multiplied, result in a special product. Sal uses the distributive property to demonstrate the multiplication process. He then explains why some polynomials cannot be completely simplified.

Here is the third video in the seven-part series focused on defining the properties of exponents. Sal defines and applies the power rule in order to simplify an exponential equation.

Using the identity property of 0, Sal evaluates the expression 0+y+ (-7). He uses multiple colors and number lines, while providing a complete explanation of his thinking process.

In video four of the seven-part series on properties of exponents, Sal simplifies a complex exponential expression to show how to apply both the quotient property and power rule.

Sal simplifies a complex exponential equation to demonstrate and apply the quotient rule. This is the second video in a seven-part series.

An interactive made up of five questions challenges mathematicians to divide integers and reflect on division properties. A moveable anchor aids in problem-solving. Question types include multiple-choice, true or false, and discussion. 

An interactive boosts mathematicians' knowledge of subtracting integers using a horizontal number line by way of multiple-choice, true or false, and discussion questions. 

There's got to be a better way. Scholars learn that the distributive property does work with subtraction and not just addition. Using that fact, the video shows how to find the product of two numbers by rewriting a complicated number as...

For a change, order does not matter. A short video provides a definition of the commutative property of addition. Pupils develop an understanding that—unlike some operations—order does not matter for addition problems.

Groupings are the way to go! The short video provides a description of the associative property of addition and gives an example. Learners view how to write the property using variables.

What properties of equality also work for congruence? Part of basic geometry playlist, the video relates algebraic properties to their counterparts of congruence. Learners see how the properties mean the same whether with equality or...

Why does the equal sign look that way? The resource explains the reason several of the math symbols look the way they do. Using a few specific examples, the video points out that some symbols are rooted in their meanings and others are...

How does all this math fit together? The resource creates a graphical view of the extent of mathematics. The map shows the pure and applied sides of studying mathematics and breaks them down into their many disciplines.
