A picture Rajon Rondo tweeted of himself teaching algebra at Burke High School in Dorchester, Mass., this morning was more than a photo op. The Celtics point guard has skills, says the class instructor.

"I'd give him an A," math teacher Kehinde Oshodi told The Huffington Post. "He was putting me on the spot asking for more problems to solve."

Rondo spent about 20 minutes at the white board, and urged students to consider the entire structure of an equation rather than just diving in to solve it, Oshodi said.

The teacher also said that Rondo used some of his lesson to show a student who had correctly solved an equation a more efficient means of arriving at the answer.

"He was on point," the teacher said.
