AREA AND PERIMETER
Students will know and be able to:o Determine the area of a rectangular shape by exploring the concept of covering a region with “unit squares”, which could include square tiles or shading on grid or graph paper.
o Count the square units to find the area in metric, customary, or non-standard square units. o Tile a rectangle, then multiply the side lengths to show it is the same. For example, to find the area one could count the squares or multiply 3x4=12. o Multiply side lengths to find areas of rectangles with whole number side lengths. o Solve real world and mathematical problems. (For example, Drew wants to tile the bathroom floor, which is 6 square feet by 8 square feet. How many square tiles will he need?) o Apply knowledge of the distributive property. For example, finding the area of two smaller parts of a figure can be used to find the total area of a figure. o Use the term rectilinear figure to describe a polygon that has all right sides. o Decompose (break apart) a rectilinear figure into non-overlapping rectangles to find its total area by adding the area of each non-overlapping section together. o Solve problems about perimeter, or the distance around a shape. o Find the perimeter of polygons by counting units on grid paper, as well as measuring with inch and centimeter rulers. o Find an unknown side length of a figure given a specific perimeter. o Find rectangles with the same perimeter and different areas, or with the same area and different perimeters. o Discuss and identify the relationship between area and perimeter. For example, a rectangle with a perimeter of 12 could be three different shapes and areas. |
