Self Review 

Your next task is to make sure you really understand what is happening. Look at any you got wrong and try to work out why. Perhaps discuss with your partner.

Go to Scratch

You will find all the code at https://scratch.mit.edu/projects/370353055/   Run a section of code by clicking on the top instruction. Investigate how it works. Scroll up to find more. Then have a go at modifying them and making your own sentences. Challenge – Can you add more sentences and change the time depending on the number of words said?

Key Question

Why might it be better to use “Say” rather than “Say for 2 seconds”? Is there a difference? Discuss this with a partner.

  • Are all the blocks connected?
  • Are the numbers in the right order?
  • is it saying the same thing but for a different number of seconds?

#3. Which program do you think will work best?

  • Are the words in a sensible order?
  • if there is no pause (wait) then it will skip to the next word straight away.
  • Does it make sense to have punctuation by itself at the end?
