Practice Path

Start with the most visual game first and watch whether the student can complete the logic and thinking task reliably. Then move into faster or more strategic games.

Keep each practice block to 8 to 12 minutes. Short rounds preserve attention and make it easier for a teacher or parent to spot which problem types need written follow-up.
