Book #9 This booklet will focus on ONLY the items in Bold Black [ ) Teachers: To assure that the above standards are understood, always remind, ask and show your students: What is the formula for finding the area of a rectangle? 2.Multiplication can be used to determine the area of a rectangle How can you divide the area of a complex shape into small rectangles to detetermine the area of the whole shape? Teacher Information... Teacher Information... 4 th Grade all standards in (Justify area measure with model, find areas of complex shapes)will be assessed in : Understanding of area and determining the areas of two dimensional shapes Recognize area as an attribute of two-dimensional regions Determine area by finding the total number of same-sized units of area that cover a a shape without gaps or overlaps Recognize a square that is one unit on a side as the standard unit for measuring area Determine the appropriate units, strategies, and tools to solving problems that involve estimating or measuring areas Connect area measure to the area model used to represent multiplication and use this to justify the formula for area of a rectangle Find the areas of complex shapes that can be subdivided into rectangles Solve problems involving perimeters and areas of rectangles and squares Recognize that rectangles with the same area can have different perimeters and that can have different areas Connect area measure to the area model used to represent multiplication and use this to justify the formula for area of a rectangle Find the areas of complex shapes that can be subdivided into rectangles.
