Hey all! I have a question about 2nd grade math standards. I was talking to a coworker who mentioned that she knows someone who teaches abroad, and their math is really just three primary skills for each grade level that are taught exclusively until mastery. Then the next year, they don't have to review and keep practicing; they already know it. So I'm curious if there would be a way to implement something similar with CCSS. I really only know 2nd grade and that's what I will hopefully be teaching next year, hence the title. 2nd Grade math covers a LOT - addition facts, basic subtraction, counting and skip counting within 1000 by 2s, 5s, and 10s, identifying and categorizing basic 2D and 3D shapes, collecting data, simple fractions (1/2, 1/3, and 1/4), and working with place value up to hundreds. This is by no means an exhaustive list, but these are the main overarching skills taught in 2nd grade, as the addition and subtraction ones also have standards involving solving word problems with one or more steps. My question is: if you were to put those into groups to really keep instruction focused to 3 or 4 main skills, how would that look? Is this even possible with common core? I like the focus that CC has on critical thinking skills, but what I've noticed is that it is a lot to learn in almost too short a time to really attain mastery of any particular standard.
