Six Holes of Arachnipod Crossing

In this Cyberchase activity, learners use the numbers one through six to solve a puzzle. Learners are challenged to arrange spiders, numbered one through six, on a triangle so that each side of the triangle adds up to nine. This puzzle was featured in "The Hacker's Challenge" episode. During this episode the CyberSquad had to solve the puzzle to get through the Arachnipod Crossing. Learners can also use the blank spiders to make a new puzzle.
