Start small. Keep your progress.

How the journey works

1. Use the optional starting check to find a useful first lesson.
2. Read the explanation and control the visual steps. Motion off leaves every step available manually.
3. Try the three practice questions for each lesson. Hints are allowed. Change an answer and check again to update the result.
4. Answer the six-question final check without hints. Explanations appear after submission; review any missed topic before trying the alternate set.
5. Write and save a reflection. Complete all three practice checks, reach at least 5 of 6 in the final check and save your reflection to finish the journey.

Completion describes this learning activity. It is not a school grade, a formal assessment or a certificate. Written proofs and projects benefit from teacher feedback.

Where your work is saved

Answers, progress and reflections are saved in this browser using local storage. They are separate from existing Grade 3 and Grade 4 school accounts, and do not sync across devices. No name, email or sign-in is needed.

Three spaces let learners keep separate work on the same browser. They are not private accounts: anyone using the same browser profile can open them. Use separate browser profiles for privacy and avoid personal details in reflections.

Private browsing, storage restrictions or clearing browser data may remove progress. If saving is unavailable, a warning appears and your work stays only in the open tab. Download your learning record before closing. The JSON download is a readable record, not an import or account backup.

Draft practice answers and reflections are saved as you change them. An unfinished final check stays only in the current tab. The latest 20 completed final-check attempts are retained.

If another tab changes the same space, reload its saved state before continuing. Clearing a chapter requires confirmation and affects only that chapter and space.

Print or use fewer animations

Download the A4 learner and solution packs from the chapter. The solutions are in a separate file. Without JavaScript, the written lessons and PDF links remain available. Motion off disables automatic step playback.

Corrections and feedback

Keep the lesson title, question text and the answer you expected when sharing feedback with your teacher or the site owner. Do not include a child's personal details.
