Graph Points on a Coordinate Plane 6 NS

Graph Points on a Coordinate Plane… 6. NS. C. 6 b

Did you know you can draw a picture just by plotting points on the coordinate plane?

In this lesson you will review how to graph points by using a coordinate plane.

In this lesson you have learned how to graph points by using a coordinate plane.

Guided Practice 1. Which of the following points correctly shows where (-4, 2) would be plotted (assume a 1 unit scale)? y x

Guided Practice 2. Which of the following points correctly shows where (3, 0) would be plotted (assume a 1 unit scale)? y x

Extension Activities Draw a coordinate plane on a piece of paper. Make some cards with coordinates on them. Make sure to use coordinates that are in all 4 quadrants. Turn the cards face down. Pick one up. By using the signs, place it in the correct quadrant. Have a friend check your work.

Extension Activities Draw a coordinate plane and label it with a scale (or use existing). Draw a simple picture. Make sure the picture has points that are on a line and use straight lines to connect the points. Write down the coordinates to all the points. Give a friend the coordinates and have them plot the picture. Did it match yours?

Extension Activities With a friend, you’re going to play coordinate battleship. Each of you needs a coordinate grid with small ships drawn on it (use rectangles for ships). Make sure the ships have coordinates that are on a line. Take turns guessing coordinates of each other’s ships. If a guess is correct mark it off and tell the other person. Play continues until all the battleships are found.

Quick Quiz 1. Which of the following points correctly shows where (5, -1) would be plotted (assume a 1 unit scale)? A y B x C D

Quick Quiz 2. Which of the following points correctly shows where (0, -4) would be plotted (assume a 1 unit scale)? A y B D x C
