Answer Keys!

CC suggests you buy the WHITE Henle Latin Answer Key
This key only has answers to every other problem.

You can find other answer keys at these sources:

Seton Books $5
http://www.setonbooks.com/viewone.php?ToView=S-L1HS-12
(Definitely has some mistakes in it)

Memoria Press $20 per book
https://www.memoriapress.com/curriculum/latin/henle-latin-teacher-manual-units-1-5/
https://www.memoriapress.com/curriculum/latin/henle-latin-teacher-manual-units-vi-xiv/
(More accurate answer key, more expensive, but a GOOD Resource for Directors and Parents as it has a "chalk talk" for teaching and practicing the material.
