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...

Learners identify the properties and use them to solve word problems. They solve 13 problems. This is an unusually good worksheet!

Show the class how to find the factors of numbers. They use a variety of strategies, including unifix cubes, to find the factors of a whole number. This resource includes clear procedure to follow. Included are an anticipatory set,...

New ReviewGet in one last practice. Pupils work through 12 problems and a performance task to review the topics in Unit 1. The problems cover analyzing and modeling with graphs, algebraic properties of equality, and adding, subtracting, and...

New ReviewProperly apply properties to arrive at equivalent expressions. Pupils review the main properties of equivalence with the guidance from the video. They take the knowledge from the video and apply the properties within the instruction and...

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. For 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 activity 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.
