Some things happen for certain, others maybe and some never.
There are three words for that: certain, possible and impossible.
There are balls in an urn (that is a bag).
You draw a ball without looking.
Example: There are full and empty balls in the urn.
I draw a full or an empty ball, that is certain (there are only those).
I draw a full ball, that is possible (there are full and empty ones).
I draw a spotted ball, that is impossible (none is spotted).

What does this exercise practice?
Learn to assess events using the terms certain, possible and impossible.
Common pitfalls
Children often mix up possible and certain. Certain means it cannot be otherwise. Possible means it might happen, but does not have to.
How to practice at home
Play with a die: is it possible to roll a 6 (yes), certain to roll a number (yes), possible to roll a 7 (no, impossible).
