There are just 3 Personal, Social and Emotional Development ELGs (this is considered a Prime learning area) and I would be surprised if the school aren't targeting activities to help your son achieve as they are considered so important.
You must understand these are life skills and not something you can teach in the way you seem to imagine.
The fact that a child isn't receptive and learning from example is a barrier to future learning. The Centre for Research in Early Childhood (CREC) identified dispositions and attitudes as a vital early indicator of success.
Prime areas of learning
Personal, social and emotional development involves helping children to develop a positive sense of themselves and others; to form positive relationships and develop respect for others; to develop social skills and learn how to manage their feelings; to understand appropriate behaviour in groups; and to have confidence in their own abilities.
ELG 06
Self-confidence and self-awareness:
Children are confident to try new activities,
and to say why they like some activities more than others. They are confident to speak in a familiar group, will talk about their ideas, and will choose the resources they need for their chosen activities. They say when they do or don’t need help.
Explanatory note:
The child makes choices within their environment and expresses their
preferences. The child tries new things, explores resources and tools, and shares their experiences
with others including adults, peers or within a group. The child plays independently expressing their
ideas and innovations and asks for support when needed.
ELG 07
Managing feelings and behaviour:
Children talk about how they and others show feelings, talk about their own and others’ behaviour, and its consequences, and know that some behaviour is unacceptable. They work as part of a group or class, and understand and follow rules. They adjust their behaviour to different
situations, and take changes of routine in their stride.
Explanatory note:
The child responds appropriately to experiences, communicating his or her
needs, views and feelings. The child is aware of the consequences of words and actions and adapts his or her behaviour accordingly. When playing as part of a group, the child takes turns and shares.
The child knows the expectations and routines of the setting, applies strategies to respond to changes of routine and offers explanations as to why these are necessary. The child is usually able to adjust his or her behaviour to reflect this understanding.
ELG 08
Making relationships:
Children play cooperatively, taking turns with others.
They take account of one another’s ideas about how to organise their
activity. They show sensitivity to others’ needs and feelings, and form positive relationships with adults and other children.
Explanatory note:
The child plays co-operatively in a group, sharing and taking turns. When
playing together with others, the child usually responds in a friendly and kind way, listening to other children’s ideas and points of view. The child interacts positively with other children and adults.
