Instructional Strategies:
•
The student will identify and trace, describe, and sort plane geometric
figures (triangle, square, rectangle, and circle) according to number of
sides, vertices, and right angles.
•
Essential Understandings(for students)
All students should
•
Develop strategies to sort and/or group plane geometric figures and refine the
vocabulary used to explain their strategies.
Essential Knowledge and Skills (student objectives)
The student will use problem solving, mathematical communication, mathematical
reasoning, connections, and representations to
•
Describe a circle.
•
Trace triangles, squares, rectangles, and circles.
•
Describe triangles, squares, and rectangles by the number of sides, vertices, and right
angles.
•
Sort plane geometric figures into appropriate subsets (categories) based on characteristics
(number of sides, vertices, angles, curved, etc.).
•
Identify the name of the geometric figure when given information about the number of
sides, vertices, and right angles.
•
•
•
•
Suggested manipulatives: Materials such as clay, yarn,
paint, etc. with which to create shapes, Geoboards &
rubber bands, solid geometric shapes, pattern shape
blocks, overhead shapes, tangrams, dot& grid paper, etc.
Trace around three dimensional shapes to make a one
dimensional shape.
Play “Shape I-Spy” with students.
Make Shape riddle books.
Play “I have, who has” with shapes.
Sort pattern blocks by various attributes.

The student will construct, model, and describe objects in the environment
as geometric shapes (triangle, rectangle, square, and circle) and explain
the reasonableness of each choice.

All students should
•
Understand that geometric figures are integral parts of the environment.
•
Use familiarity with the figure, structure, and location to develop spatial reasoning.
Essential Knowledge and Skills (student objectives)
The student will use problem solving, mathematical communication, mathematical
reasoning, connections, and representations to
•
Construct plane geometric figures.
•
Identify models of representations of circles, squares, rectangles, and triangles in the
environment at school and home and tell why they represent those figures.
•
Describe representations of circles, squares, rectangles, and triangles in the environment
and explain the reasonableness of the choice.
