NE.MA 1.1. Students will communicate number sense concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.

MA 1.1.1. Number System: Students will demonstrate, represent, and show relationships among whole numbers within the base-ten number system.

MA 1.1.1.a. Count, read, and write numbers 0 - 100

MA 1.1.1.i. Compare and order whole numbers 0 - 100

MA 1.1.1.j. Demonstrate relative position of whole numbers 0 - 100 (e.g., 52 is between 50 and 60; 83 is greater than 77)

MA 1.1.2. Operations: Students will demonstrate the meaning of addition and subtraction with whole numbers.

MA 1.1.2.a. Use objects, drawings, words, and symbols to explain addition as a joining action
