Are you looking for online 1:1 instruction or tutoring?
WyzAnt
I teach many of my online clients using the WyzAnt online tutoring app. The WyzAnt interface allows for reliable video and audio conferencing, interactive typed chats, a shared whiteboard, and the ability to share files. Visit my WyzAnt profile.
Skype & Twiddla
Another option for online lessons involves using Skype for audio and video conferencing together with a nifty interactive white board called Twiddla. In those instances, I open a new whiteboard, then send students the link so they can join me there.
Are you looking for online courses for a K-12 student?
I also teach a few courses through a fantastic website called Outschool. For these, I use the Zoom interface, which also allows for video and audio conferencing, interactive typed chats, and a shared whiteboard, as well as the ability to share screens.
Right now on Outschool, I am offering multiple sections of Introduction to Latin Courses I-IX, Individualized Word Study (Phonics, Orthography, Morphology, Etymology), Individualized Structured Multisensory Literacy Instruction, and Vocabulary Building with Latin and Greek Roots and Affixes.
