Operations and Algebraic Thinking PK.OA
Understand addition as adding to and understand subtraction as taking from.
1. Demonstrate an understanding of addition and subtraction by using objects, fingers, and responding to practical situations (e.g., If we have 3 apples and add two more, how many apples do we have all together?).
Understand simple patterns.
2. Duplicate and extend (e.g., What comes next?) simple patterns using concrete objects.
