SPACE ACADEMY · TRY, THINK, PLAY
Read original figures, distinguish their properties and use the conditions shown in a diagram.
Just a quick try. Not saved; no game rewards.

Scan the nose cone and the fins and count every triangle.
Count each triangle by part: 1 nose cone and 4 fins (1 + 4 = 5), giving 5 triangles in all.

Find how many corners each type of solid has, multiply by its count, and add the two totals.
Each cube has 8 corners (5 x 8 = 40) and each cuboid has 8 corners (1 x 8 = 8), giving 48 corners in all.

Add the heights of all columns first, then subtract that total from twelve.
First add the column heights from left to right: 3 + 2 + 2 + 2 = 9 cubes. Then subtract from 12: 12 - 9 = 3 more cubes needed.
A game mission has 8 untimed questions. Only the game saves choices and hints. A finished mission earns one launch charge and participation towards the Probe bus in Outer Planet Voyager. The chapter goal is 8 different questions in finished sets; hints and wrong answers count as participation, not mastery. Some craft systems link more than one chapter.
Foundations: read a representation and practise the underlying idea.
Paper-style reasoning: connect clues, interpret a diagram or work backwards.
Higher-order practice: link conditions, test statements and avoid a tempting wrong method.
Levels change representations, clues and conditions, not just the numbers. These are practice formats, not validated exam-equivalent difficulty.
Learning reports distinguish hinted answers from independent first choices. They consider up to 20 recent different, unhinted questions per skill and level, and wait for at least five before suggesting extra practice. Repeating the same question does not add evidence. Reports are practice evidence, not IQ scores, diagnoses, ranks or predictions of competition results.
Ask the learner to explain a drawing or check with objects too. Choose Explore or an earlier chapter when a step feels too large.
The grade topics use SOF IMO Class 2 published topic syllabus as their primary reference. The SOF sample and CREST previous-year paper below informed representations and reasoning demands. Providers have different topic boundaries; their syllabi are not interchangeable.
Questions, diagrams, picture choices, hints and explanations are original Otterly work, not copied paper questions or publisher artwork. No Olympiad provider is affiliated with or endorses Space Academy. This is not complete exam preparation; follow classroom teaching and check the current official syllabus too. Independent educator review is still needed for difficulty and breadth.
Content and coverage notes. To report a confusing question, describe the grade, chapter, level and question on the contact page. Do not send children’s personal information.
Game progress stays only in this browser, in three anonymous explorer slots. Clearing site data or closing a private session may remove it. Download a private backup from Help & saves; there is no cloud sync. The game checks saves before play and stops on save failures rather than pretending progress was saved.
These page examples never change a saved game. Game links carry question settings, not a learner’s answers. There are no names, school details, public profiles, chat, analytics or advertising SDKs in the game. Grown-up guidance · Privacy
