Y6 LF: Use lists and random

The computer’s first Christmas card!

Based on a poem by Edwin Morgan

1. Start with: reset
2. Make a list of words:
   1. make “words [“happy “merry “jolly “very]
3. Write the first part of the greeting:
   1. print [“Have “a]
4. Choose a random word from the list to print:
   1. print item random 4 :words
   2. This means “Print a random item from the list of words”  The 4 is because there are four words in the list so it chooses one from 1 to 4 in the list
5. Now make it print two words instead like this:
   1. print [item random 4 :words  item random 4 :words]
6. Put a repeat around the random words line:
   • repeat 10
   • [
   • ….
   • ]
7. Finish with:
   1. print “Christmas
8. Copy this code or make your own Christma[s picture,  You could use your snowflake code from last week.
   1. repeat 30
      [
      pu setxy random 200 random 200 pd
      repeat 18 [fd 30 rt 160]
      ]
9. *** Add more words to the list, eg berry, holly, bauble, tinsel…  and don’t forget to change the random number to the number of items in the list
10. *** Make a list of colours. Make your stars random colours.
11. *** make sure that the first word is an adjective and the second a noun by making two lists:  “adj and “nouns or “words1 and “words2
12. *** Think of another project that uses lists and/or the random function
