Unit Three Lesson 1Defining Success Using the coordinate plane to graphs vertices and derive the area formula

Unit three lesson 1 defining success using the coordinate plane to graph vertices and derive the area formula. 1Lesson 1-Section 1Plot vertices on the coordinate plane in all four quadrants. (M.6.G.3 )Determine the missing vertices of a shape using the other vertices of that shape. (M.6.G.3 ) Find the area of squares and rectangles from the coordinate graph and from their coordinate points. (M.6.G.3 , M.6.G.1 )

At the end of this lesson you should be able to plot vertices on the coordinate plane using all four quadrants to create various shapes. You will be able to find the missing vertices of a shape. You will be able to use the graph to find the area of the shapes you have created, and by doing this you will derive, or come up with, the area formula. 2Lesson 1Points A and B are plotted, plot points C and D to form a rectangle with a height of three units.

Find the area of rectangle ABCD.

A(-1,1) B(3,1) AB

By the end of lesson one you should be able to solve the following problem. You will be able to complete the quadrilateral on the coordinate plane, find its missing vertices, graph them on the coordinate plane to fit the specified dimensions and find the area of the shape you created. 3Lesson 1A(-1,1) B(3,1)

C( -1,4) D(3,4)

Quadrilateral ABCD has an area of 12 square units.ABCD

You will be able to graph points C and D to create the quadrilateral and will use the graph to calculate the area of 12 square units. In this lesson you will pull from prior knowledge and skills learned from previous units and apply them to new geometric concepts, such as area. 4
