Is grant funds from a charitable trust used for K-12 expenses recorded as income, or recorded another way?

We received some money as members of an educational association that received a grant from a foundation to help area homeschoolers with education related expenses.  I'm assuming this needs to be recorded as income, but I wasn't sure since reception of the money requires it be spent on education related and it was.  

If it should be recorded as income, is it just under Less Common Income--Miscellaneous Income?  

I did not receive any sort of official tax form regarding the distribution, simply a letter stating the full amount distributed to the association and then the check itself.
