Example from family of 4:
You read 5 chapters alone: 1 person x 5 chapters = 5
Your spouse read 5 chapters alone: 1 person x 5 chapters = 5
Your oldest child read 3 chapters to you: 2 people x 3 chapters = 6
You and your spouse read 4 chapters together: 2 people x 4 chapters = 8
You read 3 chapters to the whole family: 4 people x 3 chapters = 12
Total chapters read: 5 + 5 + 6 + 8 + 12 = 36 total chapters
(You don’t have to submit the whole family at one time but try not to double submit.)
