How we explain it

Children can open this short lesson before they practise.

  1. Read the title and the labels first.
  2. Check what each picture or bar stands for.
  3. Certain, likely, unlikely and impossible tell how likely something is.

Example: Each ⭐ stands for 2 votes. Cats have 3 ⭐. How many votes? Each ⭐ is 2 votes. 3 × 2 = 6. Answer: 6 votes
