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...

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...

Subtraction does not work with the commutative property ... or does it? Confronted with a difficult problem, the narrator realizes that by writing the subtractions as adding a negative, he can rearrange the problem. Pupils learn that 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.

Review properties of real numbers in a real way. Viewers of a YouTube video match equations to properties of real numbers in an effort to review all the properties at once.

You'll never confuse the commutative and associative properties again. Scholars view a short YouTube video that shows how to rewrite expressions using the commutative and associative properties. It takes both addition and multiplication...

You'll probably learn properties properly after viewing a video that reviews the properties of real numbers, including the identity and inverse properties. Scholars watch a YouTube video that shows how to use the properties to evaluate...

Move vectors to determine their difference. Pupils use an interactive to visualize the opposite of a vector. They use the concept of adding vectors to subtract vectors by adding the opposite and, finally, view the differences of the...

Mathematical arrays can represent several different math skills, including counting groups, multiplication, and even area. In this specific task, learners are asked to identify the addition equations that are equal to a 3 x 4 array....

Help your class find patterns in polynomial multiplication. Pupils multiply a trinomial by a binomial using a graphic organizer. They respond to questions about patterns observed in polynomial multiplication before a discussion question...

Teach about properties properly. Individuals investigate the commutative and identity properties for both addition and multiplication. They see that the properties hold true for all values by using substitution to test out several examples.

Explore the definitions of algebraic properties through a hands-on activity. Individuals cut and paste examples and match them to the correct properties. After examining the provided examples, pupils create examples of their own.

Apply properties of operations to work with mixed numbers. The first lesson of two that works with properties of operations focuses on mixed numbers and converting opposites of sums. Pupils work with properties of operations to break...

A seven-question assessment determines how well your learners understand the procedures to add, subtract, multiply, and divide signed rational numbers. Pupils show their understanding through problem-solving situations. 

The ninth part in a 25-part series emphasizes the importance of using properties of operations in evaluating sums and differences of rational numbers. Pupils solve problems and provide justifications from one step to the next.

Connect the commutative property to commuting. The quick video shows how to use the commutative property to write sums and products in a different way. It provides examples to show that the property only works for addition and...

Should matrices be allowed to commute when they are being multiplied? Learners analyze this question to determine if the commutative property applies to matrices. They connect their exploration to transformations, vectors, and complex...

To commute or not to commute, that is the question. The 26th segment in a 32-segment lesson focuses on the effect of performing one transformation after another one. The pupils develop the procedure in order to multiply two 2 X 2...

Increase understanding of the algebraic properties and their importance. Scholars justify their steps as they simplify expressions and solve equations. They formalize their work as two-column proof.

Never forget a math term with a reference sheet highlighting vocabulary found in a third grade curriculum. Three pages offer nineteen words each with a detailed definition and picture representation. Terms include ten frame, the...

The number of basic algebraic properties can become overwhelming for learners. A lesson explains and gives examples for all the basic algebraic properties. The resource is perfect to use as a way for pupils to organize and study the...
