The "Common Core"* math sheets make ME hate them. My son's third grade math sheets have him draw a picture, solve the problem using numbers, AND write an explanation of the problem and solution for EACH problem. Since we are not artistic and also enjoy handwriting difficulties, you can imagine our delight with these worksheets. /sarcasm
*Although many curriculums have absconded with the "Common Core" name, it is actually a set of standards and NOT a curriculum. It is much the same as ISO9000 is a set of standards, and your company's instructions are how you conform to those standards.
