• Develops understanding for odd and even numbers.
• Demonstrates an understanding of the fractions 1/2, 1/3, 1/4 as part of wholes.
• Recognizes the effect of an operation on whole numbers using addition and subtraction.
• Recognizes, understands, and solves different types of subtraction situations.
• Matches addition and subtraction notations to situations they could represent.
• Maintains automaticity with combinations of 10.
• Knows with automaticity addition facts to 20 and subtraction facts to 10.
