They may have previously waited till 3rd grade but then went into more depth about them. Many schools teach phonics first and then reading comprehension, however other schools teach a lot of reading comprehension and acting first and then work on phonics and fluidity. Some schools have a geography class whereas most public schools don't have geography graduation requirements. Etc. etc.
My kid had fractions in first grade, before Curriculum 2.0 (which is Montgomery County's Common Core curriculum). Singapore Math has fractions in first grade.
And here is the Common Core standard related to fractions, for first grade math:
"Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares."
Do you think that first-graders learning about halves and quarters is a recent and specific change?
