Missing Cube
Missing-cube tasks combine matrix-like pattern completion with cube-face feature comparison, supporting spatial reasoning and working-memory maintenance. Parameters adjust to the level and the task.
Example
A generated instance. Parameters such as difficulty, size, and symbol set are adjustable.
Task focus
Each task format is associated with these cognitive categories:
attention
Ability to focus on relevant information and filter out distracting stimuli. Includes sustained, selective, and switching attention.
visual perception
Processing of visual information: recognition of shapes, colors, spatial relations, objects, and faces.
spatial cognition
Understanding and manipulation of spatial relations, orientation, mental rotation of objects.
Evidence-informed format
Missing-cube tasks combine matrix-like pattern completion with cube-face feature comparison, supporting spatial reasoning and working-memory maintenance.
Format basis: structured educational activity. Name: “Missing Cube”. Cognitive focus: attention, visual perception, and spatial cognition.
How to use it
- 1Open the exercise and adjust the difficulty to the student's current level — usually it is better to start slightly easier than feels right.
- 2Read the rules. They are short, usually 10–20 seconds.
- 3Use the generated task as structured educational material, with accuracy and clarity prioritized over speed.
- 4Compare the answer with the reference and leave a human-written comment if the task is assigned through the student cabinet.
Who it's for
- •Educators and tutors — as material for lessons, review, and home practice.
- •Speech, special-education, and development specialists — for children and adults; parameters adjust to the student's level.
- •Parents — to receive clear assignments and leave comments about completion.
Frequently asked
Can I see an example without an account?
Yes. This page shows an example of Missing Cube. An account may be required to create, edit, assign, or save the complete exercise.
What is the task focus of Missing Cube?
Primarily — attention, visual perception, and spatial cognition. The full list is in the section above, with short definitions for each function.
How long does one task take?
Most generated tasks are designed for short use in lessons, homework, or individual practice sets. The exact time depends on difficulty and student level.
Can I use Missing Cube with participants?
Yes. In BrainTrainings Academy, Missing Cube can be added to a worksheet set with difficulty controls, student assignment, completion time, and comments.
