Unit at a Glance
In Kindergarten, students identified shapes and described them
according to attributes, such as number of sides, color, and
size. They recognized figures by appearance and compared them
to a known example of a shape. They also described relative
positions of shapes using terms such as above, below, in front of,
and so on. In grade 1, these concepts are extended. Students
understand that regardless of a shape’s position, color, or size, the
number of sides determines the identity of the shape which also
corresponds to the number of angles and vertices. Students at
this level are given ample opportunities to observe and compare
the attributes of different shapes. Learning the language of
geometry becomes essential to students understanding how to
classify two- and three-dimensional figures.
In Kindergarten, students named, modeled, and analyzed two- and
three-dimensional shapes. Students also used simple shapes to
make larger shapes. In grade 1, students begin their study of
geometry by building and drawing shapes according to defining
attributes. Students compose a wider variety of two-dimensional
shapes into more complex shapes than they did in Kindergarten.
This geometry unit focuses on two-dimensional shapes and the
relationships between them. Students observe, describe,
compare, classify, represent, and compose and decompose 2-D
shapes. Students learn to use geometric language to describe and
identify important features of familiar 2-D shapes. As they sort and
describe groups of shapes, they begin to distinguish specific
attributes of triangles and quadrilaterals. As a final project,
students create paper quilts by repeating combinations of
triangles and squares. The Shapes software is introduced as a tool
for extending and deepening this work. This tool is designed for K–
2 students to explore how different shapes go together,
experiment with different sorts of geometric transformations
