We had such a fantastic day at our annual Winter Crafts. A big THANK YOU to the volunteers who helped make this day happen.

❄️✂️ Winter crafts in full swing at Chinook!

Our students had so much fun creating and exploring with the help of our amazing volunteers. These moments of creativity,
connection, and joy are what make our school special.

Thank you to everyone who came in to support our classrooms. We truly appreciate you! 💙

Love seeing our students enjoy their outside time!

Students have been enjoying the snow and fresh air during outside time ❄️

Thank you, families, for sending students with warm coats, boots, hats, gloves, and snowpants so they can play safely 💙
