This document introduces Boolean logic and how it can be used to make decisions in computer programming. The lesson aims to explore using true/false logic to make decisions. An example is given of using "if/then" statements to decide whether to take an umbrella based on weather conditions. Boolean logic allows combining true/false conditions with AND, OR, and NOT to make complex decisions. The goal is to use these concepts to create instructions for a computer to choose what to bring outside based on the weather.

3. Using logic to
make decisions
from conditions

4. Lesson aim
explore true / false logic to
make decisions

5. End goal
show understaning by using
logic in computer
programming techniques

6. Example:
Weather conditions

then _____________

8. if _____________
then _____________
Can you think of an example?

9. if raining
then takeUmbrella

10. if raining
then takeUmbrella

11. if raining

12. if raining
then takeUmbrella

13. if raining
then takeUmbrella

14. if raining
then
else

15. Boolean values are
TRUE or FALSE

16. raining

then scorePoints

26. if
ANDeatsPowerPellet
then killsGhost
touchingGhost

27. if NOT touchingGhost
then continueGame
else loseLife

28. We can use
AND & OR & NOT
with TRUE or FALSE
conditions
to make complex decisions

29. Class activity:
What's it like outside?

30. Ingredients:
Green – conditions
Blue – actions
Orange – decision control

31. Goal:
Create instructions for a
computer to choose what to
take outside based on the
weather

32. Recap

33. Use Bolean
logic to
make decisions
in programs

34. Boolean values
are TRUE or FALSE

35. You can combine
them with AND & OR
Use NOT to reverse
them
