The main focus of this unit is an intensive practice with word problems, as well as hands-on investigation experiences with geometry and perimeter.

Essential Questions:

• How can we determine the attributes of different polygons?
• How can we determine the perimeter of polygons?

Essential Understandings:

• Students will understand that polygons have different attributes.
• Students will understand the different strategies for finding perimeter.
• Students will understand that rectangles with the same perimeter can have different areas or that rectangles with the same area can have different perimeters.
• Students will understand data can be organized, presented, and interpreted in multiple ways for a variety of purposes.

Skills the students will learn:

• Compare polygons and their attributes.
• Apply their basic understanding of perimeter of real world contexts.
• Determine the perimeter of a figure when whole number side length measurements are unknown.
• Measure side lengths and calculate perimeters.
• Use all four operations to solve one- and two- step word problems.

Vocabulary/Concepts:

• Vocabulary- Quadrilaterals, Polygon, Regular Polygon, Perimeter, Area
• Different shapes have shared attributes.
• Strategies for finding the perimeter.

Websites:

• Which 2 Dimensional Shape is Described
• Compare Sides and Corners
• Classify Quadrilateral Shapes
