Answer:
I would first try to tell them how to solve for something and then I would try to reward them for doing or solving if they are correct. How this system will work is because of the reward, the reward will be something that the student likes, and the reward will act as the felling of pride and joy they will get as hard work, even if it is unhealthy, they still earn it for doing and solving the problem because they tried hard. If that doesn't work, then you should try to find a video of how to solve or read something in a fun, and educational video. A fun video can be anything, whether it's a song, a tutorial, or anything, a fun video is just like recess, kids learn and try hard, and sometimes though, kids forget some minor details and how they remember and add in information, is by having a break, or in other words, fun and recess and by having fun, kids will learn about 50% more knowledge and will have a much successful learning journey. Kids will often like fun environments, but because kids, younger kids mostly have a fun environment in their minds, it is best to use all of these techniques to improve their learning process, and young minds.
