The Math Class

S2 E17: Frankie once again goes head-to-head with Brick's third grade teacher, Ms. Rinsky (guest star DORIS ROBERTS), when Brick gets a 'D' on his math test, and Frankie thinks bad teaching skills are to blame. But Frankie wonders whether or not she can make the grade when Ms. Rinsky makes her and Mike attend a class to test their own math skills. Meanwhile, Axl and Sue, while begrudgingly watching over their crusty, old aunts, mull over a plan to accompany Aunt Edie on a search for a time capsule she had buried years ago when she was young.
