Probability Teacher Resources
Lesson plans, worksheets, slides, and assessments for the formal probability strand, from Years/Grades 5 to 10. The resources cover theoretical and experimental probability, sample spaces, Venn diagrams, two-way tables, probability trees, and compound events — so you can teach the whole middle and senior probability sequence without spending the weekend pulling materials together.

What's inside the probability resources?
🔥Curriculum Aligned
Aligned to the formal probability strand.

🌍 Differentiated for Students
Theoretical and experimental probability, side by side.
💡Incredible Teacher Resources
Lesson plans and worksheets carry lower-floor and higher-ceiling tasks for the same concept. Students who need more reps on simple sample spaces get them; students ready for tree diagrams, two-way tables, and conditional probability can push ahead in the same lesson.

Structured Solutions
Differentiated Questions
Each resource maps to the Australian Curriculum v9.0 strand for probability (and reads cleanly against US state standards), with year-band tags so you can find the right level in a couple of clicks. The sequencing follows the standard middle-to-senior path: experimental probability and relative frequency first, then sample spaces, then compound and conditional events.
Real-World Applications
Engaging Exercises
Worksheets and lessons pair theoretical probability (what should happen) with experimental probability (what did happen) on the same task, so students can see the gap and discuss why long-run frequency converges. Spinners, dice, two-coin tosses, and short class-data investigations are built into the activities.

What's covered across the probability resources
Years/Grades 5 and 6: probability scales and simple sample spaces
Years/Grades 7 and 8: theoretical and experimental probability
Years/Grades 9 and 10: compound events, tree diagrams, and conditional probability
The upper-primary resources move students from chance language into formal probability — fractions, decimals and percentages on a 0 to 1 scale; listing sample spaces for one-stage events; and comparing observed frequencies to expected outcomes from short experiments. Lesson plans include the discussion prompts and the spinner, dice and coin investigations students need to see the link between theory and data.
Middle-secondary resources sit at the heart of the strand — theoretical probability for equally likely outcomes, experimental probability and relative frequency, sample spaces for two-stage events, and an introduction to two-way tables and Venn diagrams for not-mutually-exclusive events. Worksheets give structured practice with answer keys, and the assessments include short, justify-your-reasoning items.
Senior-secondary resources cover the full apparatus students need before stage 6 / AP-level probability: independent and dependent events, with-replacement and without-replacement tree diagrams, conditional probability from two-way tables and Venn diagrams, and language for mutually exclusive and complementary events. Project-based tasks and longer assessments push students to set up the problem correctly, justify the model, and check answers against the experimental data.
