Latin Numbers - Numerī Latīnī

Very useful as a collection of important number words, however, it isn't instructional in the normal sense that he lectures about numbers or their uses. Instead, it is more an activity set that encourages you to repeat the numbers either after or before he does, depending on your skill. To that end, it is useful.

I would certainly recommend reading up on some of the number concepts elsewhere to get a full understanding as there are some rules and applications that are not addressed here.
