My niece's school are also celebrating Linggo ng Wika. They are a very small school in Malanang yet they are able to give coaches gifts for all the activity coaches. But of course, it is because the parents donated a hefty sum for the activity itself. If not for the parent's donations, there wouldn't be any lively production as well as all the other events within the celebration.
I guess it is always the parents who can make or break any school activity. Without the support of parents, especially on the financial aspect, activities wouldn't really be successful.
