Ordering Likelihoods
Compare the likelihood of different events and order them from least to most likely — including situations with unequal outcomes such as a bag with more of one colour than another, or a spinner with sections of different sizes — and explain reasoning using informal language
Lesson
Set out your lesson
“Ordering Likelihoods means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Counters or paper models for the idea
- Pencil for recording
Extra for the adult
Worked example. Adult shows one clear example for Ordering Likelihoods, then the child tries a matching example with a reason.
Optional challenge. For Ordering Likelihoods, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Ordering Likelihoods, not mastery.

Check understanding
- Order four or more events from least likely to most likely and justify each placement
- Compare likelihoods when outcomes are not equally likely — e.g. 'Drawing red from a bag with 7 red and 3 blue is more likely than drawing blue'
- Explain why some events are closer to 'even chance' and others are closer to 'certain' or 'impossible'
“If a bag has 8 red counters and 2 blue ones, does your child understand that picking red is much more likely than picking blue — and can they put different events in order from least to most likely?”
