Metric Units - Mneumonics in Table (Extended) to Missing Prefix (Level 1)

This math topic focuses on understanding the metric system through the use of a mnemonic device. The mnemonic, "Terribly Gigantic Monsters Killed One Million Men Napping Peacefully," helps learners recall metric prefixes and their corresponding powers of ten. Students are tasked with identifying missing metric prefixes from a structured table across a set of problems. Each prefix represents different powers of ten, ranging from \(10^{12}\) (tera) to \(10^{-12}\) (pico). The exercises are designed to strengthen knowledge of metric units and reinforce memory about measurement units in the metric system.
