Writing grants is a great way to fund projects and programs. To date, I have brought in over $30,000 in grant funding to my elementary building. The grant highlighted in this post is from Facebook's Altoona Data Center Community Action Grant. I have received this grant three times, and this year's is for $14,700 to fund technology which will be used in our kindergarten classrooms.
If you're unsure where to begin, I encourage you to look at educational organizations you are part of, or the literacy focused blog post I wrote a while back.
If you would like support or wish to learn more about projects I have funded, don't hesitate to reach out.
Note: If you're in a school district, you will want to check whether there is a grant funding process or checklist you need to follow.
