The Teachers Funeral By : Richard Peck
What I've read about so far is that Russel who is the main character his brother Lloyd, and their sister Tansy are out on the lookout for more kids to teach at the one room schoolhouse. They have reached the Tarbox family, and they are not nice at all. None of their kids are educated and their mama refuses to let them go to school, instead she wants them to do chores around the house. The next day while Tansy's getting ready for school one of the oldest Tarbox's (probably around 17) want to learn so he goes to school. But Tansy can't teach very well because she kind of has a crush on the Tarbox kid. Then they find a snake in Tansy's desk drawer and it is three feet long, so the Tarbox kid kills it and Tansy falls in love with him.
