Oklahoma Academic Standards
OK.4.N. Number & Operations (N)
4.N.1. Solve real-world and mathematical problems using multiplication and division.
4.N.1.5. Solve multi-step real-world and mathematical problems requiring the use of addition, subtraction, and multiplication of multi-digit whole numbers. Use various strategies, including the relationship between operations, the use of appropriate technology, and the context of the problem to assess the reasonableness of results.
4.N.1.6. Use strategies and algorithms based on knowledge of place value, equality and properties of operations to divide 3-digit dividend by 1-digit whole number divisors. (e.g., mental strategies, standard algorithms, partial quotients, repeated subtraction, the commutative, associative, and distributive properties).
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.
