If you are looking for a fun and easy way to introduce your student to Latin, you might enjoy this free Beginners’ Latin Tutorial.
Through 12 interactive, online lessons the student works from conjugating verbs through adverb usage. Practice sentences, interactive activities and a checklist at the end of each lesson help the student evaluate their understanding before moving on. No prior Latin knowledge is required.
For added interactive value, consider having your child keep a Latin notebook as he works through the course — outlining the material, copying examples, and keeping a section for exercises.
