Paperdolls are so much fun. But they can also teach you to recognise foundational concepts of computer science. In these exercises you’ll learn about two concepts: Boolean expressions and Selection.

Booleans

• On Mondays Ruby wears green and red clothes.
• On Tuesdays Ruby dresses up in clothes with polka dots or stripes on them.
• On Fridays Ruby wears clothes that are not black.
• On weekends – Now it’s your turn to decide Ruby’s dress-up rule!

Selection

• If it’s raining, Ruby wears [POINT AT THE RIGHT CLOTHES], else she wears [POINT AT THE RIGHT CLOTHES].

• If Ruby goes to the beach, she packs with her [POINT AT THE RIGHT CLOTHES], else she will do [COME UP WITH AN ACTIVITY] and wear [POINT AT THE RIGHT CLOTHES] .

*If it’s her birthday, Ruby wears [POINT AT THE RIGHT CLOTHES], else she wears [POINT AT THE RIGHT CLOTHES] .

More play ideas

• Design your own paper clothes, shoes, glasses, and the like. Then come up with a rule Ruby would approve.
• Cut and fold a closet for Ruby’s clothes. How many different ways can you sort the clothes?
• Build a paper version of Ruby’s room.
