In this Grade 3 vocabulary lesson from Vocabulary from Classical Roots (Book 4), students explore the Latin roots mot (to move) and numer (number) to build understanding of eight words including motivate, motive, numerator, and numerous. Exercises guide students through synonyms, context-based fill-in-the-blank practice, and the adjective suffix -less using motionless as a model.
