New ReviewSubtraction 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...

New ReviewFor 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.

Add a great resource to a unit on addition properties. Scholars watch a short YouTube video to learn about the addition properties of real numbers. They see, through examples, how they can apply properties to rewrite addition expressions...

Only three choices exist here—commutative, associative, or distributive. Through an informative video, viewers learn about the commutative, associative, and distributive properties. Given several numerical equations, they identify which...

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....

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.

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...

Explore properties of addition as they relate to matrices. Using graphical representations of vector matrices, scholars test the commutative and associative properties of addition. They determine if the properties are consistent for...

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...

Support first grade math vocabulary with a reference page divided into three sections—the vocabulary word, its definition, and a picture representation. Terms include number bonds, arrow notation, commutative property and more! 

Using their knowledge of the associative and commutative properties of addition, class members work with fact families to create two addition and two subtraction problems with three given numbers. 

Sixteen number families test young mathematicians' knowledge of the commutative and associative property of addition. Pupils list four problems—two addition and two subtraction—related to a given set of three numbers.

Associative property of addition, exponents, and variables are a few of the terms that a set of flash cards includes and are designed to support math vocabulary instruction. Cards offer a a bold-faced font as well as a thorough...

When Gauss's teacher asked the class to find the sum of the numbers from 1 to 100, he quickly realized a relationship and discovered a formula that made finding the answer easy. Share this video with young mathematicians after posing the...

Hands-on learning in math is essential to all learners, especially youngsters. In a math learning activity, young mathematicians use dominoes in order to discover the commutative property of addition. Fact families and doubles facts can...

Three tables, prepared for learners to write notes about the properties of real numbers, are squeezed onto one printable. The addition and multiplication of real numbers are the focus of the notes.

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...

So you have an expression of positive and negative numbers and you want to add and subtract them. Do you do the operations in order that they are written? Do you combine some? Do you move them around? Do you change their signs? The...

These fact families need to be completed. Scholars use addition and subtraction to complete four number sentences for each set of three numbers. The sentences are all part of the number set's fact family, and demonstrate the commutative...

Learners complete a math worksheet. They go over five "topsy turvey" (commutative property of addition) examples as a class and determine how many fish are in the fishbowl. They write the number sentence and then rewrite the sentence...

A cute little frog helps learners hop from number to number on the number line as they count on to add. They use the commutative property of addition to add the same numbers two different ways. A cute, simple, and potentially helpful...
