RI.M:N&O:1. NECAP - Grade Level Expectation: Number and Operation.
M:N&O:1:2. Demonstrates understanding of the relative magnitude of numbers from 0 to 100 by ordering whole numbers; by comparing whole numbers to each other or to benchmark whole numbers (5, 10, 25, 50, 75, 100); by demonstrating an understanding of the relation of inequality when comparing whole numbers by using '1 more', '1 less', '5 more', '5 less', '10 more', '10 less'; and by connecting number words (from 0 to 20) and numerals (from 0 to 100) to the quantities and positions that they represent using investigations, models, representations, or number lines.
M:N&O:1:3. Demonstrates conceptual understanding of mathematical operations involving addition and subtraction of whole numbers (from 0 to 30) by solving problems involving joining actions, separating actions, part-part whole relationships, and comparison situations; and addition of multiple one-digit whole numbers.
M:N&O:1:6. Mentally adds and subtracts whole numbers by naming the number that is one or two more or less than the original number; and adds and subtracts whole number facts to ten (e.g., 5 + 3 = 8; 8 - 5 = 3).
