Experimental probability- bin it
If you’re looking for a nice task to introduce experimental probability, get pupils to throw scrunched up paper balls into the bin from a distance and recording their number of successes and misses. Pupils love this activity and you can get a lot of learning from it:
- demonstrating something that doesn’t have equally likely outcomes and so requires an experiment,
- relative frequency,
- expected number of outcomes (“What if they threw 500? How many would we expect them to get in?”),
- how increasing the number of trials makes the probabilities more reliable,
- probability of missing = 1 – probability of getting it in.
Do a girls vs boys comparison and you’ll have the class very engaged 🙂
