My older 2 do a lot of their homeschooling online and independently now, and I tend to focus on my younger 2. I depend on my older ones to tell me if they are having problems in math or whatever. I learned by looking at grades that my oldest was having an issue in math. I said, “Well why didn’t you tell me?” It isn’t like I am not right there. I always ask if any help is needed and it is always no. She said, “I didn’t want to bother you”. The child is doing pre-calculus. If she needs help I can help her. I am literally in another room with the other two kids. What is the point of homeschooling if you are not getting good grades? My threat is you may as well go to public school if you have these grades. That tends to work. She has been doing better. Half way through the course now. My youngest loves science too. She has only 2 weeks worth of work left of her 36 week science course. She plows through it. She is studying about planets now. She was so upset when we were done studying about the human body. That was her favorite. She loves these youtube videos made by a science teacher in New Jersey. His name is Mike DeMaio. Here is one video as an example.
