  7. 3) If the story continued and you know how many grains of rice Rani receives on Day 30, how can you determine how many grains of rice she would receive on Day 31? • 4) How can you determine how many grains of rice she would receive on Day 35? • 5) How can you determine how many grains of rice she would receive on Day 40? Class discussion

  8. 6) If you know how many grains of rice she receives on a certain day, how can you determine how many grains of rice she will receive 2 days later? . . . 10 days later? • 7) Write a sentence that describes how many grains of rice Rani receives each day. • 8) What is the rate of change? Is this a common difference or a common ratio?

  9. 9) Use the words NOW and NEXT to write a rule to express the pattern. The NOW-NEXTform is the recursive process of getting from one number to the next number in the sequence. • 10) How do the numbers and calculations used in your NOW-NEXT rule express the pattern of change in the rice table (number of day, rice received)? • 11) Write a sentence that describes the total number of grains of rice Rani will receive through a certain number of days.

  10. 12) Test each of your equations to see if they generate the values in the table. Were your algebraic equations correct? If not, modify your equations and test them until you are certain they are correct. Record the changes you make so that you can explain to others how you arrived at your final equations.

  11. 13) Graph the first ten days of the rice reward on the graph to the right. Be sure to label your axes and title your graph. Is this a graph of a linear function or an exponential function?
