• We at Tumwater Hill are using resources from Sanford Harmony to support our community's social-emotional learning (SEL). Families have access to Sanford Harmony online resources as well. Here's a letter you can access from your child's TSD Google account that explains more information about Sanford Harmony. To access the online resources, go to the Sanford Harmony site. Click the button that says "Sign Up Now." On the next page, click "Register Now for Free!" You will create a free account. Once you have done so, click "Go Now!" under the Sanford Harmony section of the page. From here, you will have access to many SEL materials that you can use at home with your family.
