OK.4.N. Number & Operations (N)
4.N.1. Solve real-world and mathematical problems using multiplication and division.
4.N.1.7. Determine the unknown addend or factor in equivalent and non-equivalent expressions. (e.g., 5 + 6 = 4 + ☐, 3 x 8 < 3 x ☐).
OK.4.A. Algebraic Reasoning & Algebra (A)
4.A.2. Use multiplication and division with unknowns to create number sentences representing a given problem situation.
4.A.2.1. Use number sense, properties of multiplication and the relationship between multiplication and division to solve problems and find values for the unknowns represented by letters and symbols that make number sentences true.
4.A.2.2. Solve for unknowns in problems by solving open sentences (equations) and other problems involving addition, subtraction, multiplication, or division with whole numbers. Use real-world situations to represent number sentences and vice versa.
