Writing pseudocode is helpful when we are creating computer programs.
 This is because:

• Pseudocode tells us whether a conditional statement is true or false.

• Pseudocode allows us to run our programs multiple times in a row.

• Pseudocode can only be used when programming in Scratch, but not in other programming languages

• Pseudocode lets us write out step-by-step descriptions to help us figure out how to make our programs do what we want them to do.
