Reallotment


 * Overview**: This unit is in the Geometry strand (measurement sub-strand). The goals of the unit are to give the students conceptual understanding of what it means to measure length, area, and volume and the retlationships that exist beteen them. They also begin to develop an understanding of how changes made to the length impact the perimeter and area of a figure.


 * Section A:** In this section, students explore the concept of area using figures on grids and various arrays.


 * Section B:** This section extends the content of section A and introduces more formal vocabulary.


 * Section C:** This section continues the students exploration with the concept of area with a focus on the use of appropriate units and tools to estimate and determine length and area. This section also builds the students abilty to use the metric and customary system to find length and area.


 * Section D:** In this section, the students explore the concept of perimeter and circumference. They explore how changes in one-dimension effect the perimeter and area of various figures. Students also explore how to determine the area and circumference of a circle by investigating and discovering the meaning of Pi.


 * Section E:** The activities in section E focus on developing a students understanding of volume and surface area. They work with packing crates and buildings to determine volume and surface area. They also learn the appropriate units to represent each.
