For such children, my previous practice was: the formula didn't explain too much to TA, and the explanation of TA might not be understood, so I copied it directly, at least 50 times; Every time you go to cram school, you can bring a snack or a small gift (just one or two yuan), saying that you will be rewarded after learning today's content. Remember not to have the same thing every time. Try to play with TA first. Generally speaking, the topic is given three times. Try to guide TA to think. When TA comes up with the answer under your guidance, TA will be very happy and will further stimulate TA's desire to learn. After I did this, the effect was still obvious. At least that baby will get high marks in the math exam next month. Good luck!
