Max and Molly arrive for the first day at their new school named after H.G. Wells—only to discover things may not be what they seem. A mysterious new classmate and a message from Aunt Murgatroyd kick off a new mission involving time travel and an undercover threat. Their assignment: travel back to 1842 to meet Ada Lovelace and stop a shadowy group (The Power-Hunger P.O.G.S.) from misusing the first computer algorithm.

Math Concepts: Percentages and proportions (e.g., identifying .083% of students as possible spies); Exponents and squaring numbers (e.g., 2×2, 4×4, 16×16); Logical thinking and conditional statements (If/Then logic) Algorithm basics; Pattern recognition

History/Geography Concepts: Ada Lovelace and Charles Babbage’s Analytical Engine; The origins of computer programming in 19th-century London; The idea of "moles" (spies) infiltrating organizations; H.G. Wells as a historical figure and author of The Time Machine
