Great post above. Practice this summer in showing all of the steps. Sometimes assuming you know something and jumping over the steps leads to errors. Enough practice and she can mentally go through the steps. I remember in college having essay type exams for math and science courses. The method was more important than the final number. She’ll get the correct answer with the correct logic by going step by step. Perhaps she could check out her last year’s textbook from her school to review material not as thoroughly learned.
