3.11b

3.11  Measurement. The student directly compares the attributes of length, area, weight/mass, and capacity, and uses comparative language to solve problems and answer questions. The student selects and uses standard units to describe length, area, capacity/volume, and weight/mass.

2.9a  Identify concrete models that approximate standard units of length	3.11b  use standard units to find the perimeter of a shape	4.1a  Estimate and use measurement tools to determine length (including perimeter), area, capacity, and weight/mass using standard units metric and customary
Use standard units to find the perimeter of a shape Use:  to employ for some purpose; put into service; make use of Find:  to locate, attain, or obtain by search or effort; to discover or ascertain through observation, experience, or study

Activities:

• Model with color tiles or grid paper creating a shape, discussing the standard unit of measure
• Draw a line around the perimeter of the shape, labeling each side then totaling the perimeter
• Use color tiles to create figures that represent a given perimeter. 
• Use poster graph paper to create models that represent a perimeter that is discerned by rolling a dice, drawing a card (Eliminate the 1 and 2), or spinning a spinner

• Measure various polygons using inches and centimeters
• Record each side of the shape to find the total perimeter
• Compare and order the total perimeters of the polygons
• Categorize polygons according to the total perimeter withing a range--graph the perimeter of ranges
• Given a polygon with missing information, find the missing info to find the total perimeter

Anchor Activities:

• Use geoboards to create a shape and find the perimeter
• Create polygons using the color tiles or on graph paper and find the perimeter
