1. Area of Squares, Rectangles, Parallelograms, and Triangles

2.  The area of a shape is the number of square units contained within it.  This shape has an area of 5 square units, or 5 units²

3.  Rectangles are made up of equal-sized rows of unit squares. Therefore, multiply how many squares are in each row by the number of rows.  Area of rectangle = length x width

6.  Squares are specific rectangles so their area is also calculated by length x width. However, since all sides are equal, we can say  Area of square = side x side = side²

9.  Parallelograms can be turned into rectangles so they also share the same area formula.  Make sure you use the base and the height, which are perpendicular (form right angles with each other).  Base = 5 m and height = 3 m because they form a right angle. The 4 m (called slant height) is not used at all.  Area = base x height = 5 m x 3 m = 15 m²

14.  A parallelogram can always be divided into two triangles with the same base and height.  Since base x height is the area of the full parallelogram and a triangle is only half of a parallelogram, multiply by ½  Area of a triangle = ½ x base x height

17. Direct Station  We will go through a Pearson lesson which focuses on finding the area of other shapes.  Remember, the way we found the total degrees in any polygon was to split it up into simpler shapes. Perhaps we can use a similar strategy for area.

18. Independent Station  You will complete an activity and game in order to review perimeter of rectangles and then complete a Google Form.  Make sure your sound is off!
