Impossible, possible or certain worksheets

Chance starts with three words. These free printable worksheets show a bag with four to six shapes in it and ask about picking one without looking. Count what is there, then circle impossible, possible or certain. An answer key is included.

Impossible, possible or certain
Impossible, possible or certain worksheet — Bags of 4 to 6 shapes, free printable with answer key

The answer key prints on a separate page.

What's on this sheet

The three words come straight out of the picture. If the bag holds no circles, picking a circle is impossible. If every shape in the bag is a square, picking a square is certain. If there is at least one circle among other shapes, picking a circle is possible, and it stays possible with one circle or with four.

Why this sheet works

That last point is the one worth talking about. A bag with one circle and five squares feels like "no," and a child's first answer is often impossible. It is not, because that one circle could come out. The numbers are small on purpose, so the page is about what the words mean and not about counting. The maker can also draw each question as a spinner.

How this one works

Pick one without looking. A circle is

3 squares and 3 stars
impossible
  1. Count what is there: 3 squares and 3 stars, 6 in all.
  2. There is no circle at all, so it is impossible.
