Sorting and classifying shapes
Sort a group of shapes by one attribute: count each kind, or circle every shape that matches.
Experimental and theoretical probability
Use a table of results from a spinner, die or coin to compare what should happen with what did happen.
About this worksheet
Each experiment shows a table of results. Students write the theoretical probability (what should happen if every outcome is equally likely), the experimental probability (what actually happened out of all the tries) and how many times they would expect an outcome.
The results are close to the expected numbers but never exactly equal for the outcome that is asked about, so the two probabilities always differ a little. Fractions are written in simplest form.
