MAFS.4.OA.1.a

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.
Subject Area: Mathematics
Grade: 4
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.
