Content Area: Math
Index: 4.2A Grade 2 CPI 2
Standard: 4.2 - Geometry and Measurement
Strand: A - Geometric Properties
Cumulative Progress Indicator: 2 - The student will use concrete objects, drawings, and computer graphics to identify, classify, and describe standard three-dimensional and two-dimensional shapes. · Vertex, edge, face, side · 3D figures – cube, rectangular prism, sphere, cone, cylinder, and pyramid · 2D figures – square, rectangle, circle, triangle · Relationships between three- and two-dimensional shapes (i.e., the face of a 3D shape is a 2D shape)
Grade: 2
Sample Activities:
· Students make shapes with their fingers and arms.
· Students listen to and look at the book The Shapes Game by Paul Rogers. Each page shows a different shape and many of the things in the world that have that shape. As each page is read, the children find other objects in the room that have the same shape.
· Students listen to and draw illustrations for the story The Greedy Triangle by Marilyn Burns.
· A good open-ended assessment for this critical indicator is to ask students to sort a collection of shapes into groups, explaining their reasoning. Some groups they might consider include "all right angles" or "four-siders." The teacher should encourage the students to invent appropriate group names and to use informal language to describe the properties, and should record the students' responses to look for progress over time.
· A more traditional, but still useful, assessment strategy is to ask students to sort pictures cut from magazines according to shape. This more focused task will generate information about the students' ability to recognize and differentiate among shapes.
· Students make class books shaped like a triangle, a rectangle, a square, and a circle. They fill each book with pictures of objects that have the shape of the book.
· Students turn a geometric shape into a picture. For example, a triangle might become a tower, a clown face, or the roof of a house.
