The "bare bones" type of skills you are referring too are NOT taught in first grade. In our homeschool, first grade math starts with addition and subtraction. My kids are reading by first grade, though we do continue with phonics lessons. The same is true for local public schools as well. Children are adding and subtracting at the end of kinder and reading CVC words by March of their kinder year, or they are held back. The idea that colors and shapes are taught, even in review, in 1st grade is laughable. My kids are done with colors/shapes by their 3rd birthday.
