We've started to swing back towards visual and geometrical models with common core/new math.
But I have a big collection of math textbooks from all over the world, and math 6, pre-algebra and algebra texts in the US have far less geometrical content and pictures than the non-US equivalents that I have. I also think that the increased emphasis on getting students through standardized tests ended up dedicating a lot of class time towards rote with short term benefits.
