Probability Progress Outcome (Relevant to Y4/5):
Understand: That some events are more likely to happen than others.
Know: Probability outcomes (theoretical and experimental) can be represented using lists, tables, tally charts, words (e.g., certain, likely, unlikely, impossible, equally likely), and numbers (fractions/decimals/percentages—focus on words and fractions for Y4/5).
Do: Investigate questions involving chance, compare and explain the likelihoods of outcomes for a simple situation, and match the results of chance-based investigations with statements.
