It’s time to challenge young minds with Complex Arithmagons. This is a set of engaging math puzzles designed for learners aged 10–14. Each square in the arithmagon contains a number that is the sum of the two numbers in the adjacent circles. Using addition only, students must work logically to find the missing values in each puzzle.

These printables are ideal for:

• Strengthening mental addition and logical thinking

• Early finishers, math stations, or enrichment activities

• Building confidence with number relationships
