Education for 2 Tanzanian Children

In our daughter's class there are two students who will not be able to continue their education unless they receive financial support for next academic year.  One lost his father last year and his mother can't afford next year's school fees.  The second has 2 working parents who receive a discount from the school, but even so, can't pay the remaining fees.  I'm trying to raise money to keep them both in the school for next year (and beyond).
