Reason with shapes and their attributes (Standards 1-3).

Standard 1.G.3

Partition circles and rectangles into two and four equal shares; describe the shares using the words halves, fourths, and quarters; and use the phrases half of, fourth of, and quarter of. Describe the whole as two or four of the shares. Understand that, for these examples, decomposing into more equal shares creates smaller shares.

• Equal Shares
  This purpose of this task is for students to understand how to partition shapes into equal pieces.
• Geometry (1.G) - First Grade Core Guide
  The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for First Grade Mathematics - Geometry (1.G)
• Grade 1 Unit 6: Understanding Shapes and Fractions (Georgia Standards)
  In this unit, students will study and compose two- and three-dimensional figures, identify basic figures within two- and three-dimensional figures, compare, contrast, and/or classify geometric shapes using position, shape, size, number of sides, and number of angles, solve simple problems, including those involving spatial relationships, investigate and predict the results of putting together and taking apart two- and three-dimensional shapes, create mental images of geometric shapes using spatial memory and spatial visualization, relate, identify, partition, and label fractions (halves, fourths) as equal parts of whole objects and apply terms such as half of, quarter of, to describe equal shares.
