Unit 5 Identifying, Composing, and Partitioning Shapes Grade 1 Math 


Description: Students think about attributes of shapes and
practice composing and decomposing geometric shapes. This provides important
“internalization time” for students between two intense numberbased units to
build their confidence before they return to place value and operations.

Enduring Understandings: ·
Twodimensional
and threedimensional shapes can be identified based on defining attributes
of the shape. ·
Twodimensional and threedimensional shapes
can be used to compose new shapes. ·
Students
will decompose twodimensional and threedimensional shapes to create new
shapes, with a focus on decomposing circles and rectangles into halves and
fourths. 
Essential Questions: ·
How can I tell about shapes? ·
Where can shapes be found in my world? ·
How can I sort and tell about shapes? ·
How are shapes alike? Different? ·
How can I use twodimensional and
threedimensional shapes to compose new shapes?
