Determine whether an equation is true or false by using comparative relational thinking. For example, without adding 60 and 24, determine whether the equation 60 + 24 = 57 + 27 is true or false.

### General Information

Subject Area: Mathematics
Domain-Subdomain: Operations and Algebraic Thinking
Cluster: Level 3: Strategic Thinking & Complex Reasoning
Cluster: Use the four operations with whole numbers to solve problems. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

#### Formative Assessments

 Name Description True and False Multiplication Equations Students are asked to determine if each of two equations is true without performing any operations. True and False Division Equations Students are asked to determine if each of two equations is true by comparing mathematical expressions and without actually carrying out the indicated calculations. Determining If an Equation Is True Students are asked to determine if each of two equations involving subtraction is true by comparing mathematical expressions and without actually carrying out the calculations. Are the Equations True? Students are asked to determine if each of two equations is true without performing any operations.

#### Lesson Plans

 Name Description Can You Compare and Find the Missing Number In an Equation? Students will be able to compare and solve equations using comparative relational thinking. This lesson only addresses addition, not the other operations. Solving these equations will require the students to mentally evaluate to determine if it is true or false. The students will also determine the unknown number in some equations. Is my equation TRUE or FALSE? In this lesson, students will determine if equations are true or false and justify their reasoning using relational thinking.
