G.2 - Geometry

This text resource illustrates the Standards Map for the Grade 2 Geometry domain in the Common Core State Standards.

Standards

Common Core Mathematics: G.2

In Grade 2, instructional time should focus on four critical areas: (1) extending understanding of base-ten notation; (2) building fluency with addition and subtraction; (3) using standard units of measure; and (4) describing and analyzing shapes.

Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

A. Circles and rectangles can be partitioned into equal shares and described.	A.1 What are equal shares? How can circles and rectangles be partitioned? A.2 How can the equal parts of partitioned circles and rectangles be described? A.3 What results when equal shares of a shape are decomposed into more equal parts?
