Grade 2 - Comparing Numbers Unit
The Comparing Numbers Unit involves understanding the relative position and magnitude of whole numbers, and their relationships within the numeration system. Students will answer questions such as—
- Which number is greatest? Least? How do you know? How can you use symbols to show these relationships?
- How can you order these numbers from least to greatest? How can you prove you are correct?
- How can you use a number line to show the relationships between these numbers?
Math Concepts and Skills:
The student compares whole numbers and understands place value relationships.
The student:
- uses place value to compare and order numbers up to 1,200 and describes the comparison using words, numbers, and symbols (>, <, or =).
- assigns the position of a specific whole number on a number line and identifies the number that corresponds to a given point on a number line.
