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.1. Grade Level Indicator: Number and Number Systems: Compare and order whole numbers up to 10.
NNSO.10. Grade Level Indicator: Meaning of Operations: Model and represent addition as combining sets and counting on, and subtraction as take-away and comparison. For example:
NNSO.10.b. Count on (forward) and count back (backward) on a number line between 0 and 10.
NNSO.2. Grade Level Indicator: Number and Number Systems: Explain rules of counting, such as each object should be counted once and that order does not change the number.
NNSO.3. Grade Level Indicator: Number and Number Systems: Count to twenty; e.g., in play situations or while reading number books.
NNSO.4. Grade Level Indicator: Number and Number Systems: Determine 'how many' in sets (groups) of 10 or fewer objects.
NNSO.B. Recognize, classify, compare and order whole numbers.
NNSO.F. Count, using numerals and ordinal 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 Representations: Model a problem situation using physical materials.
