DS6 is in 2nd and math accelerated to 3rd.

In math so far this year he has gone over fact extensions, parts-and-total number stories, the partial-sums addition method, three or more addends, measurement, and maximums, minimums, medians, and range, and will soon go over perimeter and area, circumference and diameter, multiplication number stories, divison with counters and in number stories, arrays and area, and multiplication triangles. They use (grrr) Everyday Math.

She thought she could, so she did.
