Assist your child with projects (but let your child do the work.)
Know the profiles and attitudes and use the vocabulary with your child when it fits the situation.
Encourage your child to ask questions. Model both how to ask questions and how to find the answers.
Nurture your child's curiosity. Talk frequently, go to museums, go to libraries, encourage your child to try new things.
Ask questions about your child and her/his day at school. Specific questions elicit more detailed answers. (i.e. "What did you learn in mathematics today?"; "What are you doing in your unit of inquiry?"; "What are you working on in Language?")
Ask follow-up questions. (i.e. "Oh, it's been ages since I learned fractions! Can you show me what you learned today after dinner?")
Recognize your child when he/she shows one or more of the IB/PYP profiles. Your approval is a powerful way to reinforce the elements of the learner profile.
Encourage your child to read books that are related to the current unit of inquiry being covered in school.
Help your child to become a better thinker by allowing him/her to solve problems and make decisions on his/her own.
