The student must be able to choose examples of shapes or objects that have been cut into halves and fourths. They must also be able to identify shapes or objects that have not been cut into halves and fourths and explain their reasoning.
a) Determine all of the rectangles that are partitioned into fourths, and explain how you determined if the rectangles were not partitioned into fourths.
b) Determine the shapes that have been divided in halves. Look at the ones you did not identify and explain why you did not identify them.

1.6 Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:
(H) identify examples and non-examples of halves and fourths
