VT.7.6. Mathematical Understanding: Arithmetic, Number, and Operation Concepts: Students understand arithmetic in computation, and they select and use, in appropriate situations, mental arithmetic, pencil and paper, calculator, and computer.
MK:1. Demonstrates conceptual understanding of rational numbers with respect to whole numbers by connecting oral number words and numerals (up to and including two-digit numbers to 50) to the quantities they represent using physical models and representations and shows correct sequence of cardinal numbers.
MK:2. Demonstrates understanding of the relative magnitude of numbers from 0 to 50 by ordering whole numbers; by demonstrating one-one correspondence; and by showing the relationship between whole numbers (1 more, 1 less). Apply number parameters consistent with MK:1.
