Probability that clicks — Years 4 to 10
Probability is one of the most intuitive topics in maths — it is about how likely things are — but the notation can hide the simple idea underneath. Claritute keeps the idea in front.
Free for 7 days, then $25/month.
Understanding probability
Students usually grasp "likely" and "unlikely" easily; where they slip is turning that into fractions, listing all the outcomes (the sample space), and handling two-step events. Claritute builds each of these with clear diagrams and tables.
Lessons run from the language of chance in primary, through theoretical and experimental probability, to two-step and compound events in high school. Aligned to the NSW Stage 2–5 chance and probability outcomes.

Why families choose Claritute
Find the missing block — fast
A short diagnostic pinpoints exactly which earlier skill is causing the trouble, then builds the plan around it. Foundations first; confidence follows.
Then it’s their turn — every time
Every concept is drawn, not described — 800+ original diagrams — and each worked example hands the pen back with a matching question and a self-check.
Built and taught by Angelo Hanna
Every lesson is written, checked and taught by a registered NSW teacher and mapped to the NSW K–10 syllabus — so home lines up with school. Not scraped, not outsourced.

Frequently asked questions
When does probability start in NSW?
It begins in primary as "chance" (around Years 4–6) and develops into formal probability through high school, including two-step events in Stage 5. Claritute covers the whole progression.
What is the difference between theoretical and experimental probability?
Theoretical probability is what should happen based on the outcomes (a fair coin is 1/2 heads); experimental probability is what actually happens when you try it. Claritute teaches both and how they relate.
Is there a free trial?
Yes — 7 days free with full access. After that it is $25 a month for the whole Years 3–10 library.
