You want your child to learn the importance of planning & sequencing. Not bad, what and where would you start with? Observe how well he is doing in school and whether he is able to write down his thoughts in a logical sequence or not?
What you need to know:
If your kid is doing so, then well done! He has already taken his first step towards learning- planning and sequencing. Expressing his own thoughts logically and in a sequence is his first lesson of planning. Encourage him to write down what he feels, plan his day in advance, pack his bag at night before the next day at school, then only will he understand the importance of planning.
