    Forgive me, but this mode of acceleration seems awfully excessive, especially with the new standards. I hope that this rush through standards isn’t at the expense of the students love or like for math, or conceptual understanding of math. I am also left to wonder of the preparation of the middle school and K-5 teachers. Are they prepared to teach high school courses? Do your K-5 and MS teachers have math degrees? Are they prepared to teach these new standards, which are already radically more rigorous? “Algebra 1″ and “Algebra 11″ are just the names of the courses. In our district, the standards that are in these courses are radically different and more rigorous than we had in the past.
    I am curious about your data… do many students who complete this mode of acceleration enter an elite university in a STEM field? or complete a degree in a STEM field? Lots of questions…

    Is P(7th grader) compound?
    I am curious to the answer to Steve’s question.

    I am a bit confused by the following terms, and I find disagreements in definitions in resources:
    1. uniform probability model vs. uniform distribution – are these the same?
    2. compound events vs. multi-stage events
    According to the NCTM Navigating through Probability 6-8 book, a compound event is “an event that consists of more than one outcome”. Two examples given are P(one heads and one tails) is compound because there two outcomes from the sample space for one heads and one tails, and P(rolling a prime number).
    However, in our textbook CCSS supplemental materials a compound event is defined as “an event that consists of two or more single events”. Is this describing a multi-stage event? i.e. flip a coin, spin a spinner.

    I am wondering how the term “compound event” is to be interpreted in SP.8? As more than one outcome, or more than one event (multi-stage)?

    Thank you very much for your help!
