4Use join inside a say block to show text and a variable together		DThe sprite shows a thought bubble with the text and it stays on the stage until another looks block changes it

Answer Key

Looks blocks: say and think

Section A: Quick Questions

A — say Hello!

B — say Hello! for 3 seconds

A — think Hmm...

B — say (join Score: (score))

A — The speech bubble disappears

Section B: Match the Pairs

say [Hello!] for 2 seconds → The sprite shows a speech bubble with Hello! and then the bubble disappears after 2 seconds

think [Hmm...] → The sprite shows a thought bubble with the text and it stays on the stage until another looks block changes it

Use the say block to give output to the user by showing a speech bubble with text → say [Welcome to my game!]

Use join inside a say block to show text and a variable together → say (join [Score: ] (score))

say (Score: score) → The text and the variable are not joined, so the block cannot show both. The join block is needed: say (join [Score: ] (score)).

say [Good luck!] for seconds → The number of seconds is missing. A number is needed, like say [Good luck!] for 2 seconds, so the block knows how long to show the bubble.

Section C: Definitions

say — The say block makes a sprite show a speech bubble with text, so the program can give output to the user. Say for 2 seconds hides it after a time. Use join to add a variable.

Section D: Fill in the Blanks

say "Hello!" for 2 seconds

think "I wonder..."

say (join "Score: " (score))

set score to 10
say (join "Score: " (score))

Section E: Spot the Error

B — The words are in the wrong order. The block must read: say [Hello!] for (2) seconds, with the number between 'for' and 'seconds'.

A — Say only shows a speech bubble. It does not wait for the user to type. The first line must be ask [Your name?] and wait so that answer has a value to join.

C — Putting the word score inside the text only shows the word 'score'. Use join with the variable: say (join [Score: ] (score)).

A — The time must be the number 2, not the word two. Round brackets around a word look like a variable. It should be say [Hello!] for (2) seconds.

B — [answer] is plain text, so the bubble would say the word 'answer'. The answer reporter goes in round brackets: (answer).
