Alicia’s goal is to teach to the uniqueness of the child in an authentic and meaningful way while integrating with the PYP curriculum.  Students will focus on integrating the Units of Inquiry with a variety of literature from both fiction and non-fiction texts to acquire reading and writing skills. Students will also learn how to incorporate the “Writing Traits” into their writing.  In addition to valuable reading and writing knowledge, they will practice listening and oral skills by presenting their writing pieces to others, working in small groups and participating in class. Alicia’s teaching style includes a variety of instructional strategies such as modeling, differentiated small group instruction, the use of student rubrics, peer and teacher conferences, and inquiry based model practices.
