I recommend sitting at your table. Prepare like you are preparing a lesson for a church class. Use videos, tell stories, draw picture. Have your kids teach parts.
I have had many family home evening lessons crash and burn. So far the 3 weeks have been 10 x better. Spirit is stronger. I fasted and have prayed much for success. Some kids struggle during lessons and it seems to rotate through kids but it’s been a huge blessing to our family.
