Oklahoma Academic Standards
OK.4.N. Number & Operations (N)
4.N.1. Solve real-world and mathematical problems using multiplication and division.
4.N.1.2. Use an understanding of place value to multiply or divide a number by 10, 100 and 1,000.
4.N.1.3. Multiply 3-digit by 1-digit or a 2-digit by 2-digit whole numbers, using efficient and generalizable procedures and strategies, based on knowledge of place value, including but not limited to standard algorithms.
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).
