The rule from each lesson
IdeaThe rule
WordsEach block becomes one line of plain words. The lines keep the block order. An indent shows what is inside a repeat.
NamesNaming a group does not change which blocks run. It changes how many lines you read.
NumbersA named block can take a number. The same lines run each time, on the number you hand in.
ReadingRead the steps in order. A set line replaces the old number in the box.
Exact textA person forgives a small slip. A machine reads exactly what is typed.

What is pseudocode?

  • A language a machine runs
  • The same steps, written in plain words
  • A list of block colours

A program has a repeat block with one block inside it. It also has one block after the repeat. How many lines?

  • 2
  • 3
  • 4

What does an indent show in pseudocode?

  • That a line is more important
  • What is inside a repeat
  • That a line runs twice as fast

The line "Draw a dot." sits indented under "Repeat 3 times:". How many dots are drawn?

  • 1
  • 3
  • 4

A group of 3 blocks is used 4 times. It is written out. How many lines?

  • 3
  • 7
  • 12

The same group is named. The definition has 4 lines. There are 4 calls. How many lines?

  • 4
  • 8
  • 12

A group of 3 blocks is used 2 times. What does naming it save?

  • 2 lines
  • Nothing
  • 6 lines

A group is used 6 times. Written out or named, which runs fewer blocks?

  • Named
  • Written out
  • Neither. The same blocks run.

What is a parameter?

  • The name of a block
  • A box on a block that takes the number handed in
  • A block that repeats

A named block draws a row of n dots. It is called with 4, then with 2. How many dots in all?

  • 2
  • 4
  • 6

A block is called with 5, then 6, then 4. How many definitions are there?

  • One
  • Two
  • Three

The count starts at 0. Steps: set count to 2, draw a dot, draw a dot. Each dot adds 1. What is the count at the end?

  • 2
  • 4
  • 0

The count starts at 0. Steps: draw a dot, draw a dot, set count to 1. What is the count at the end?

  • 1
  • 2
  • 3

A machine knows "set_count(0)". It is given "Set_count(0)". What happens?

  • It runs, since a capital S is close enough
  • It may refuse it. A capital S is a different letter.
  • It changes the S for you

How are a block program and a text program related?

  • They are different programs
  • They can say the same steps. Text is stricter to type.
  • Blocks skip some steps
