Class 6 Computer Science — Making decisions in programs

Test whether a condition is true, and work out which branch of an if-otherwise step a program takes.

Name: ________________________

  1. 1.A program says: if the number is equal to 6, print "Six"; otherwise print "Not six". The number is 8. What does the program print?

  2. 2.A program says: if the number is less than 5, print "Low"; otherwise print "High". The number is 5. What does the program print?

  3. 3.A program says: if the mark is at least 40, print "Pass"; otherwise print "Fail". The mark is 39. What does the program print?

  4. 4.Is 7 more than 10?

    • a) Sometimes
    • b) Yes
    • c) There is no way to tell
    • d) No

  5. 5.A program tests a number and takes one of its two branches. In a single run, how many of the two words does it print?

    • a) One
    • b) Two
    • c) It changes each time
    • d) None

  6. 6.Sort each of these statements by whether it is true or false.

    Groups: True · False

    • 5 is less than 2
    • 8 is more than 3
    • 4 is more than 4
    • 9 is more than 2
    • 10 is less than 10
    • 7 is equal to 7

  7. 7.A program says: if the number is more than 10, print "Big"; otherwise print "Small". The number is 7. What does the program print?

  8. 8.A program says: if the mark is at least 40, print "Pass"; otherwise print "Fail". The mark is 40. What does the program print?

Answer key — Class 6 Computer Science — Making decisions in programs

  1. 1. Not six
  2. 2. High
  3. 3. Fail
  4. 4. d) No
  5. 5. a) One
  6. 6. 8 is more than 3 → True; 5 is less than 2 → False; 7 is equal to 7 → True; 10 is less than 10 → False; 4 is more than 4 → False; 9 is more than 2 → True
  7. 7. Small
  8. 8. Pass
