Pokemon Brilliant Diamond and Shining Pearl help kids practice and improve the following skills:

Working Memory: Recalling and retaining information in our minds while working.

In order to battle gym leaders, Team Galactic, and other trainers successfully, the player needs to remember the types of Pokemon they have and their strengths and weaknesses. All Pokemon have types they are strong and weak against. For example, if you are battling a rock type Pokemon, you need to use a water, grass, fighting, ground, or steel Pokemon. Otherwise the attacks will not be effective, leaving your Pokemon open to taking more damage than they are giving. Players need to keep this information in their head in real time as they are switching Pokemon in and out of battle depending on what rival Pokemon they are encountering. For players who need assistance, the game does let the player know which attacks are Super Effective and Not Very Effective so they can at least determine the extremes when sending their Pokemon out. 

Organization: Arranging and coordinating materials in order to complete a task.

Players also need to have a good understanding of what is in their inventory and how to best manage it before they begin their journey. The player will need many things in order to be successful such as potions, antidotes, PokeBalls, and other healing items. If the player does not organize their inventory before leaving a town, they may find that they encounter a fight where they are ill-equipped and do not have enough supplies to heal their Pokemon, capture a Pokemon they want, or revive a fainted party member. Much like checking your backpack before leaving for school at the beginning of the day, players should check their inventory before leaving a town to make sure they are stocked with the items they need the most.
