A good ability to concentrate makes it easier for children to engage in an activity for a longer period of time. Some children find it difficult to concentrate even for a few minutes. They are restless, easily distracted, or show little perseverance. To promote concentration, it is helpful if children does not spend too much time in front of the television or playing computer games. Lack of sleep and insufficient physical exercise also contribute to poor attention. Sufficient exercise in the fresh air and playing board games can improve children's concentration. Children love card games such as Black Peter. Black Peter is a simple card game that is suitable for children aged 4 and up. The aim is to collect as many pairs of cards with the same motif as possible. The single card with Black Peter is the losing card. First, shuffle all the cards well and deal them evenly to all players. Then, each player sorts out all the pairs of pictures. The child begins and draws a card from the other player. If the card matches a pair, the child names the picture and puts the pair aside. The child then draws another card. Once the child cannot form another pair, it is the next player's turn. The player who lays down all their cards first wins the game. As with all preschool games, it is advisable to give your child a sense of achievement. Therefore, give your child the opportunity to win the game so that they continue to enjoy playing.
