In Kindergarten,  students focus on oral language development through interactive read aloud, content knowledge building, morning meeting and play.  Phonological awareness skills and phonics are taught daily to help students acquire foundational literacy skills necessary for beginning reading.  General content knowledge and vocabulary are developed through thematic units using  the Amplify Core Knowledge Language Arts resource. Beginning writing skills are included as part of phonics and Amplify CKLA.  Letter formation is also emphasized in Kindergarten.  Small groups both extend and reinforce necessary skills for all students.

In mathematics, Kindergarten students begin to develop important foundational numeracy skills.  They build these skills  through repeated practice with counting objects and by learning how to represent, read, and write numbers through 20.  Students develop a sense of 5 and 10 and build fluency of relationships within 10.  Students at this age model and solve story problems through 10 using both addition and subtraction.  Children also explore concepts such as geometry as they learn attributes of shapes and patterns using their bodies and objects in the classroom.  We want students to see the beauty and wonder of numbers and recognize that math is all around us!

The PYP trans-disciplinary framework offers kindergartners  authentic opportunities to focus on key developmental abilities. Teachers create learning experiences and environments that meet the needs of our youngest learners.  Play is a central focus of this approach that allows children to develop language, knowledge and the approaches to learning.
