Sample Space Teacher Resources
Lessons, worksheets and assessments that take students from listing simple outcomes to building tree diagrams and two-way tables for compound events. Designed for probability units across the middle and secondary years and aligned to the Australian Curriculum (v9.0) and US state standards.

What’s Included in the Resources for Sample Space?
🔥Curriculum Aligned
The sample space pack covers every representation students need: written lists, grid tables, tree diagrams and two-way tables. Each format is introduced with a worked example, then practised on familiar contexts like coin tosses, dice rolls, spinners and card draws so the structure clicks before the numbers do.

🌍 Differentiated for Students
Resources move from single-event sample spaces (rolling one die) to compound events (rolling two dice, drawing two cards), with tree diagrams and two-way tables doing the heavy lifting. Real contexts like sports tournaments, weather forecasts and game shows keep the maths grounded.
💡Incredible Teacher Resources
Extension questions include compound events with replacement and without replacement, two-way tables linking categorical data to probability, and tree diagrams with three stages. These prepare students for the probability strands that appear in senior maths courses.

Interactive Resources
Practice Questions
Differentiation is built in: scaffolded outcome lists for students new to probability, and extension problems that move into conditional probability, sample space restrictions and counting principles for stronger students preparing for senior probability work.
Structured Solutions
Differentiated Questions
Use the lesson plans, slides and worksheets to walk a class through one experiment at a time. Students list the sample space, count favourable outcomes, then calculate theoretical probability — the same loop that anchors every later probability topic.
Real-World Applications
Engaging Exercises
Hands-on tasks let students generate their own sample spaces by rolling, flipping and spinning. They then compare experimental results to the theoretical sample space, which makes the link between counting outcomes and predicting probability visible.

Lessons, slides and worksheets for every representation
From sample space to theoretical probability
Compound events, tree diagrams and two-way tables
The pack covers the four representations students need to fluently describe a sample space: written lists, grid tables, tree diagrams and two-way tables. Lessons start with single experiments — coin tosses, single dice rolls, single spins — so students see how each format records every possible outcome. Worked examples, guided practice and independent worksheets follow the same structure, so students can move between representations without losing the link to the underlying experiment.
Once students can list a sample space, the resources move to counting favourable outcomes and calculating theoretical probability as a fraction, decimal or percentage. Activities pair the sample space with experimental data so students compare predicted and observed results, then discuss why short experimental runs can deviate from theoretical probability. This is the foundation every later probability topic — compound events, conditional probability, expected value — builds on.
For compound events, students use tree diagrams to map two- and three-stage experiments (such as drawing two cards or flipping three coins) and two-way tables to handle independent events with two attributes. Extension tasks introduce sample spaces with and without replacement, restricted sample spaces and the start of conditional probability — preparing students for the probability strands that appear in senior maths courses, including VCE General/Methods and US AP Statistics.
