Articulation of Individual Standard M:3 Multiple Meanings of the Operations. Introduction: Conceptual knowledge of the basic four operations (add, subtract, multiply, and divide) while Standard M:4 refers to the procedural knowledge of the algorithmic part of the operations. Kindergarten MK: 3 Demonstrates conceptual understanding of mathematical operations involving addition and subtraction by solving problems involving situations in which one adds to, takes from.First grade M1: 3 Demonstrates conceptual understanding of mathematical operations involving addition and subtraction by solving problems involving situations in which one adds to, takes from, puts together, and takes apart, or adds. Second grade M2: 3 Demonstrates conceptual understanding of mathematical operations involving addition and subtraction of whole numbers by solving problems involving joining actions, separating actions, part-part-whole relationships, and comparison situations; and addition of multiple one-digit whole numbers. (See Appendix A.) Third grade M3: 3 Demonstrates conceptual understanding of mathematical operations by describing or illustrating the inverse relationship between addition and subtraction of whole numbers; and the relationship between repeated addition and multiplication using models, number lines, or explanations. Fourth grade
M4: 3 Demonstrates conceptual understanding of
mathematical operations by describing or illustrating the relationship
between repeated subtraction and division (no remainders); the inverse
relationship Fifth grade M5: 3 Demonstrates conceptual understanding of mathematical operations by describing or illustrating the meaning of a remainder with respect to division of whole numbers using models, explanations, or solving problems. For
