Locked In!

Episode Description: After successfully turning the POGS’ Prediction Calculator against itself, Max and Molly discover the system has evolved beyond its programming and is now consolidating power inside the iconic Atomium in Brussels, Belgium.

Episode Description: After gaining Aunt Murgatroyd’s reluctant approval to work with Mr. Conklin, Max and Molly face their biggest coordination challenge yet: shutting down five POG servers across time simultaneously. When Conklin proposes uploading a secret virus instead, the team must weigh the mathematical probabilities of Plan A versus Plan B. As each Problem Solver races against a 30-minute timer in different historical eras, they discover even the smartest strategy can be hacked.

Episode Description: While hiding out at an overnight sleepover at the London Science Museum, Max, Molly, Charlene, and Katrina search for the final hidden POG server. Along the way, they’re forced to work with Mr. Conklin, their old Math teacher and former troll, whose Math & pop culture skills may prove invaluable. But even after the Math is solved, shutting down the server proves trickier than expected.

Episode Description: With the Time Radio repaired, Max and Molly learn the location of the final POG server — hiding in plain sight at the London Science Museum. Joined by Charlene and Katrina, they must use algebra, fractions, and logical patterns to narrow their search and unlock a hidden server before time runs out. But when they realize they’re being followed, solving Math problems becomes more urgent than ever. Math Concepts:  Circumference, radius, diameter & Pi; Dividing by fractions (flip and multiply); Algebraic expressions and variables; Lattice multiplicationHistory/Geography Concepts: History of computing & calculation; Charles Babbage & the Difference Engine; Ada Lovelace & early programming; John Napier & Napier’s Bones (1617); Early calculators & mechanical computation

Episode Description: When the Time Radio malfunctions, Max and Molly accidentally jump to the wrong time and place — landing on a volcanic island moments before the historic Krakatoa eruption! To fix their device, they explore buoyancy, density, and the physics of springs using Hooke’s Law. With time literally running out, teamwork and Math become their only way home. Math Concepts: Density and buoyancy; Volume and displaced water; Unit comparison and real-world measurement; Hooke’s Law (F = –kx);History/Geography Concepts:  The Krakatoa volcanic eruption (1883); Indonesian geography (Sumatra, Java, Rakata Island); Early scientific observation of sound waves and pressure.

Episode Description: The day starts with Max trying to score goals on the soccer field – but ends with the Problem Solvers trying to meet their goal of finding the next server.  This takes them back to Ancient Greece and the legendary Colossus of Rhodes statue.   There the foursome of Max, Molly, Katrina and Charlene use unit conversions, time calculations, and problem-solving to outsmart history without changing it. But when a shadowy figure appears, they realize the POGs may be closer than ever. Math Concepts: Circumference and diameter of a circle; Using π (Pi) to calculate diameter from circumference; Unit conversion (feet to inches, cubits to inches/feet); Area comparison using real-world objects (soccer balls vs. goal size); Multiplication strategies (mental math using ×11); Time calculationsHistory/Geography Concepts:  The Colossus of Rhodes and the Seven Wonders of the Ancient World; Ancient Greece (Rhodes, 230 BCE); The Siege of Rhodes; Ancient measurement systems (cubits); Greek mythology (Helios, Oracle of Delphi)

Episode Description: The Problem Solvers follow a musical clue back to 17th-century Istanbul, where math, music, and history collide at the workshop of legendary cymbal maker Avedis Zildjian. Using solfège, fractions, percentages, and number patterns hidden inside familiar melodies, the team unlocks a musical combination protecting a POG server. But teamwork — and patience — are tested as they race to shut it down before moving on to the next threat.
