OH.NNSO. Number, Number Sense and Operations: Students demonstrate number sense, including an understanding of number systems and operations and how they relate to one another. Students compute fluently and make reasonable estimates using paper and pencil, technology-supported and mental methods.
NNSO.10. Grade Level Indicator: Meaning of Operations: Recognize that a quotient may be larger than the dividend when the divisor is a fraction.
NNSO.11. Grade Level Indicator: Computation and Estimation: Perform fraction and decimal computations and justify their solutions; e.g., using manipulatives, diagrams, mathematical reasoning.
NNSO.12. Grade Level Indicator: Computation and Estimation: Develop and analyze algorithms for computing with fractions and decimals, and demonstrate fluency in their use.
NNSO.8. Grade Level Indicator: Meaning of Operations: Represent multiplication and division situations involving fractions and decimals with models and visual representations.
NNSO.H. Use and analyze the steps in standard and non-standard algorithms for computing with fractions, decimals and integers.
NNSO.I. Use a variety of strategies, including proportional reasoning, to estimate, compute, solve and explain solutions to problems involving integers, fractions, decimals and percents.
