 * 1. Identify and select appropriate units to measure angles; i.e., degrees.**


 * 2. Identify paths between points on a grid or coordinate plane and compare the lengths of the paths; e.g., shortest path, paths of equal length.**


 * 3. Demonstrate and describe the differences between covering the faces(surface area) and filling the interior (volume) of three-dimensional objects.**


 * 4. Demonstrate understanding of the differences among linear units, square units and cubic units.**


 * 5. Make conversions within the same measurement system while performing computations.**
