Homework
Pseudocode
You will be given a home learning sheet to complete
for homework this term.
Complete challenge 2
Your teacher will explain what you need to do.
Due:
Understand how to use nested if
statements in your programming
1. Use nested if, elif, else
function
2. Correctly identify the flow of
data through a program
By the end of this lesson you will be
able to ....
ALL
(Level 4)
MOST
I know the difference between, and appropriately I can use if and
if, then and else statements.
(Level 5)
I can use a range of operators and expressions e.g. Boolean, and
applies them in the context of program control.
SOME
I can use nested selection statements.
