I am also trying to make a decision regarding delaying math. I am very intrigued by Benezet's work, but I plan to use mainly Waldorf. I'm wondering if math is taught in the whole to parts, practical way that Waldorf approaches it if it might be better to go ahead and start slowly. My teaching materials say something like learning math teaches concentration and diligence. Maybe this would be the point of starting something earlier rather than waiting until it is easier later? Or could these habits be aquired another way without the risk of ruining her mental math skills? I haven't "taught" any math yet. My daughter is almost 6 and can multiply, divide, estimate measurement and work with fractions all from practical experience. She would fail a standardized test because she has no idea what those things look like on paper, but orally give her a recipe to triple or ask her how much each ticket is if the whole family based on what bill I gave the teller and how much I got back and watch her go. The question is would math instruction enhance this early learning or squash it? And if I don't do the Waldorf math blocks, what will we do instead? I think the math blocks are there in part to give a break from language arts so I'd want the replacement block to serve that function.
