Frankie comes up with a plan to stay on top of her kids' schedules; Brick's new teacher (Doris Roberts) accuses Frankie of being overprotective.

Frankie once again goes head to head with Brick's third grade teacher, Ms. Rinsky, when Brick gets a D on his math test and Frankie thinks poor teaching skills are to blame. But Frankie wonders whether or not she can make the grade when Ms. Rinsky requires that she and Mike attend a class to test their own math skills. Meanwhile, while begrudgingly watching over their crusty, old aunts, Axl and Sue mull over a plan to accompany Aunt Edie on a search for a time capsule she buried when she was young.

With only three days left until summer vacation, Frankie is ecstatic that she's made it through another school year with the family. But her happiness turns to panic when she and Mike learn that Brick needs to write a daily journal and turn it in to Ms. Rinsky or risk not moving up to the fourth grade; that Axl hasn't fulfilled his required 30 days of community service; and that, because of an error, Sue must prove that she never took a sick day from school in order to receive a perfect attendance award at her middle school graduation ceremony.
