Ms. Deanna Ninh


Dear Cheetah Parents and Families:

As most of you know, our school is experiencing positive change as some of our students transition to Onsite Learning while some will remain in Remote Learning. I want to thank you for supporting your child(ren), no matter your child's learning situation.  Please continue to stay connected with our teachers and support staff, so that we can help your student through these changes. 

Our Social Emotional Learning programs include wonderful services such as In-Class Lessons, small Friendship Groups, Cheetah Café and Café Tuesdays.  Cheetah Cafe is a Schoology Course, where "Cheetah Friends" can socialize, learn SEL concepts and discuss them with other students. Cafe Tuesdays is a weekly schoolwide Zoom session for all students - we meet on Tuesdays at 3:30! Each week is a different topic, but they're all designed to be social, fun and address SEL topics for Cheetah Friends. To learn more about these programs, please visit Cheetah Cafe in Schoology and talk with your child!

If you're seeking social emotional support, guidace or to chat about any questions or concerns you have - I am here for you!  Together, we can explore solutions that can help your child's continuing growth at Challenger. Your child's social, emotional and mental well being are a top priority for us. Below, are some ways you and your child can connect with me.  Please reach out in whatever way works best for you.  Let’s continue to work hard for an exciting, fun and creative school year!
