My student is older and we went with A Beka DVDs this year. She enjoys the daily classrooms and it works well for her. Today she just finished up lesson 127 today, so we are in the home stretch for this year. fyi...A Beka will have streaming at a discount next year for those who prefer it, but for me the DVDs in hand are perfect.
No curriculum is perfect for everyone;). I had dd watch both samples and we attended displays to view the books and video lessons. She prefers the A Beka and I'm comfortable with the TMs, overall program and results. Disclaimer, she has used ABeka successfully in the past without the DVDs making her transition easy. Ds...is not interested in any video lessons BJU or ABeka:001_huh:.
When mine were both using Calvert, the adjustment was a trial to say the least. My dd using the A Beka program leaves me free to work with my younger ds. Transitioning two different grades into any program is definately something to think about.
Do your research and look for what will work consistently day after day in your home. I truly have come to believe that it is the daily work that works best.
