It is essential that these standards be addressed in contexts
that promote problem solving, reasoning, communication, making connections, and
designing and analyzing representations.Problem Solving Links
4.3 Measurement: Develop
an understanding of area and determine the areas of two-dimensional shapes.
4.3.1
Recognize area as an attribute of two-dimensional regions.
4.3.2
Determine area by finding the total number of same-sized units of area that
cover a shape without gaps or overlaps.
4.3.3
Recognize a square that is one unit on a side as the standard unit for
measuring area.
4.3.4
Determine the appropriate units, strategies, and tools to solving problems that
involve estimating or measuring area.
4.3.5
Connect area measure to the area model used to represent multiplication and use
this to justify the formula for area of a rectangle.
4.3.6
Find the areas of complex shapes that can be subdivided into rectangles.
4.3.7
Solve problems involving perimeters and areas of rectangles and squares.
4.3.8 Recognize that rectangles with the same area can have different perimeters and that rectangles with the same perimeter can have different areas.
