Numbers! For a long time, I was stymied about how to begin. The first week is short in my school, only three days before Labor Day. Too short to begin in earnest... so what to do?
I teach numbers. Numbers are a great two day lesson. It's a self contained lesson -requiring no explanation of parts of speech, cases or genders. I know it's not the first unit in your textbook. It's not the first in mine either. Numbers give students confidence. They sound like the Spanish numbers they already know just slightly more exotic. They are listed in the back in the reference section. Flip the the back and get everybody counting and then ask them to add:
How many chairs in your room?
How many posters on the wall?
How many pairs of sneakers?
How many dwarves? (septem)
How many nazguls? (novem)
How many bears? (tres)
What if the bears met the dwarves? (decem)
What if One Direction met the bears and Justin Bieber?
(*Honesty, I forget but some of your students will know)
Then, on Day 2, play Latin battleship. Board is in the Hilara drive. It's just like regular battleship but students need to say the numbers in Latin to each other. Battleship takes about 30 minutes to play. After two days of numbers, your students will go home and count aloud in Latin to their parents or any adult they can get to listen to them.
