• 126.22. (c ) 7j  control structures
  
• 126.22. (c ) 8c  extend the learning environment
  

  Objectives
  

• Students will be able to trace through different types of control structures
  
• Students will be able to design a  program using control structures
  
• Students will be able to implement different control structures in a program
  

  Time Required
  

  1 week of 45 min class periods
  

  Materials Required
  

• Demonstration program
  
• Colored Index Cards
  
• Colored Chalk
  

  Procedure
  

• Have all the students stand up.
  
• Students will do 5 jumping jacks counting as they go.
  
• Write the algorithm for this
  
• Students will do 5 jumping jacks and do not say the number until they are finished.
  
• Write the algorithm for this
  
• Convert the algorithms into code.
  
• Compare and Contrast the algorithms- You may use a graphic organizer, venn diagram etc.
  
• Students will do jumping jacks for 1 minute
  
• Have each student tell how many they did
  
• Write the algorithm
  
• Convert the algorithm into code
  
• Compare the While loop with the For Loop
  
• Create a program that will display a line of information 10 times
  
• Now play ” who can code this program in ___ lines”
  
• Note: You are looking for the least amount of lines still following programming standards and readability.
  
• Tell the students to create a program the will print out 100 times I will not use the internet without teacher approval.
  
• See who comes up with the loop program
  
• Take practice loop problems and put them on colored index cards 5- 10 different problems on each color card
  
• Divide the class into groups – giving each a different color
  
• Hand the group a piece of colored chalk that matches their index cards
  
• The students as a group will solve the loop problems.
  

  Closure
  

• Students create a program that uses a loop.
  
• Have the students create a program that  prints out all the even numbers form 1 to 1000
  
• Have students create a crayon box with 16 crayons ( graphics mode)
  

  Evaluation 
  

  Chalk assignment:
  

  Students call you over when they are done with the loop problem if it is correct 10 points, subtract 1 point every time they call you over and it is incorrect. They get 10 chances.
  

  Extension Activity
  

  Students will code a program using loops. The level of the program can be modified due to ability.
  

• The American Flag with nested Loops.
  
• Draw a picket fence.
  
• Output the multiples of 3 from 10 to 1000.
