Lesson 3 Concept Development

Problem 1: Construct a coordinate plane.

Problem 2: Use coordinate pairs to name and plot points.

1. Use the grid below, to complete the following tasks.

b. Construct a perpendicular y-axis that passes through points C and F.

c. Label the origin as 0.

d. The x-coordinate of B is 5 2/3. Label the whole numbers along the x-axis.

e. The y-coordinate of C is 5 1/3. Label the whole numbers.

2. For all of the following problems, consider the points through on the previous page.

a. Identify all of the points that have an x-coordinate of 3 1/2.

b. Identify all of the points that have a y-coordinate of 2 2/3.

c. Which point is 3 1/2 units above the x-axis and 2 2/3 units to the right of the y-axis? Name the point and give its coordinate pair.

d. Which point is located 5 1/3 units from the y-axis?

Lesson 4 Homework

Your homework is to play at least one game of Battleship with a friend or family member. You can use the directions from class to teach your opponent. You and your opponent should record your guesses, hits, and misses on the sheet as you did in class.

When you have finished your game, answer these questions.

1. When you guess a point that is a hit, how do you decide which points to guess next?

2. How could you change the coordinate plane to make the game easier or more challenging?

3. Which strategies worked best for you when playing this game?
