Grades 4 and 5 are where a child starts carrying more of the load alone: longer assignments, harder math, more decisions of their own. Allison has taught this exact age for ten years, and she runs a classroom where the standard is high and the help arrives before a child has to ask for it. Math curriculum design is her own field of work, so when your child meets the wall that fractions and long division put in front of every fourth grader, she can already see which step came loose.
