OK.1.1. Algebraic Reasoning: Patterns and Relationships - The student will use a variety of problem-solving approaches to model, describe and extend patterns.
1.1.4. Recognize and apply the commutative and identity properties of addition using models and manipulatives to develop computational skills (e.g., 2 + 4 = 4 + 2, 3 + 0 = 3).
OK.1.2. Number Sense and Operation - The student will read, write and model numbers and number relationships. The student will use models to construct basic addition and subtraction facts with whole numbers.
1.2.2. Number Operations
1.2.2.a. Develop and apply the concepts of addition and subtraction.
1.2.2.a.ii. Perform addition by joining sets of objects and subtraction by separating and by comparing sets of objects.
1.2.2.a.iii. Demonstrate fluency (i.e., memorize and apply) with basic addition facts to make a maximum sum of 10 and the associated subtraction facts (e.g., 7+3=10 and 10-3=7).
