There’s a Coordinate Graph For That

Scripture: Genesis 24

Learning Objectives:

  • Students will review the story of Isaac and Rebekah.
  • Students will learn Rebekah provided about 25 gallons of water for each of the servant’s camels.
  • Students will learn how to use coordinates to place points on a coordinate graph.
  • Students will participate in an activity helping them practice using coordinate pairs to create a coordinate graph..

Guiding Question: How does one use coordinate pairs to place points on a coordinate graph

Materials:graph paper, pencils

Procedure: Review the story of Abraham focusing especially when he sent his servant to find a wife for Isaac. Explain how Rebekah gave each of the servants camels about 25 gallons of water. Show the students how Rebekah could have demonstrated the amount of water she needed for various numbers of camels by using the data to create a coordinate graph. Demonstrate how to place points on a coordinate graph for her situation. (The points to plot would be [1,25] [2,50] [3,75] [4,100] etc.) Give students graph paper and other points to plot. Have them practice plotting various points on the graph.

Additional Questions:

  • How does one plot points with coordinate pairs containing a negative number?

Supplemental Activity: Have more advanced students repeat the activity using all four quadrants of a coordinate graph. Teach them how to plot points with a coordinate pair containing one or more negative numbers. Have students practice plotting a variety of points in each of the four quadrants.
