    A generated instance. Parameters such as difficulty, size, and symbol set are adjustable.

    Task focus

    Each task format is associated with these cognitive categories:

    arithmetic abilities

    Performing mathematical operations, understanding numbers and quantitative relations.

    attention

    Ability to focus on relevant information and filter out distracting stimuli. Includes sustained, selective, and switching attention.

    processing speed

    Pace of perceiving, analyzing, and responding to incoming information.

    Evidence-informed format

    The number-snake maze uses boustrophedon numbering and 2-opt path shuffling to combine mental arithmetic with attentional and working-memory load.

    How to use it

    1. 1Open the exercise and adjust the difficulty to the student's current level — usually it is better to start slightly easier than feels right.
    2. 2Read the rules. They are short, usually 10–20 seconds.
    3. 3Use the generated task as structured educational material, with accuracy and clarity prioritized over speed.
    4. 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.
