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...

Mathematicians walk through the problem-solving process with a nine-minute video that focuses on adding mixed numbers with like and unlike denominators. The host points out and discusses how to use the stacked form, carry, regroup, and...

Get 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...

Properly 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.

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....

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...

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...

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.

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...

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...

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...

Students 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...
