    CLASS DOJO is now available.  On it, I have posted supplimental information, guidelines, and therapeutic activities in the areas of sensory calming, fine motor activities, Theraputty exercises, and handwriting. Many of you have accepted my e-vite to join Class Dojo. Please feel free to  contact me with any questions, and continue to send photos of your child's work. Remember to record all OT activities on your child's work log.

    Thank you for your continued support.

    Stay safe and be well.

    With best regards,

  • 3/13/2020     Dear OT Families,

    Attached above please find various occupational therapy related activities for your child to do during this extended school closure.  I will be posting daily assignments which you can find under  "Assignments."  Detailed instructions for the assignments can be found under "Classroom Expectations."  Thank you for your continued support during this time. Please contact me if you have questions or concerns at my school email:   I am available Monday - Friday 8:30 am - noon.

    Please know that our school pets are safe and being cared for during this interim period. The ducks and turtle are at my friend’s farm. The fish tank ecosystems were deemed to be self-sufficient, and the custodians will be feeding the fish. The ducks and turtle will return to WHS-29.
