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.12. Grade Level Indicator: Computation and Estimation: Analyze and solve multi-step problems involving addition, subtraction, multiplication and division using an organized approach, and verify and interpret results with respect to the original problem.
NNSO.13. Grade Level Indicator: Computation and Estimation: Use a variety of methods and appropriate tools for computing with whole numbers; e.g., mental math, paper and pencil, and calculator.
NNSO.K. Analyze and solve multi-step problems involving addition, subtraction, multiplication and division of whole numbers.
NNSO.L. Use a variety of methods and appropriate tools (mental math, paper and pencil, calculators) for computing with whole numbers.
OH.PFA. Patterns, Functions and Algebra: Students use patterns, relations and functions to model, represent and analyze problem situations that involve variable quantities. Students analyze, model and solve problems using various representations such as tables, graphs and equations.
PFA.4. Grade Level Indicator: Use Algebraic Representation: Use rules and variables to describe patterns and other relationships.
PFA.5. Grade Level Indicator: Use Algebraic Representation: Represent mathematical relationships with equations or inequalities.
PFA.C. Write and solve open sentences and explain strategies.
PFA.D. Represent an unknown quantity as a variable using a symbol, including letters.
PFA.E. Use variables to create and solve equations representing problem situations.
