7.SP.C.5
1.2.1
Understand that the probability of a chance event is a number
between 0 and 1 that expresses the likelihood of the event
occurring. Larger numbers indicate greater likelihood. A
probability near 0 indicates an unlikely event, a probability around
1/2 indicates an event that is neither unlikely nor likely, and a
probability near 1 indicates a likely event.
7.SP.C.6
Approximate the probability of a chance event by collecting data
on the chance process that produces it and observing its long-run
relative frequency, and predict the approximate relative frequency
given the probability. For example, when rolling a number cube
600 times, predict that a 3 or 6 would be rolled roughly 200 times,
but probably not exactly 200 times.
7.SP.C.6
1.2.2
Approximate the probability of a chance event by collecting data
on the chance process that produces it and observing its long-run
relative frequency, and predict the approximate relative frequency
given the probability. For example, when rolling a number cube
600 times, predict that a 3 or 6 would be rolled roughly 200 times,
but probably not exactly 200 times.
7.SP.C.7b
Develop a probability model and use it to find probabilities of
events. Compare probabilities from a model to observed
frequencies; if the agreement is not good, explain possible sources
of the discrepancy.
Develop a probability model (which may not be uniform) by
observing frequencies in data generated from a chance process.
For example, find the approximate probability that a spinning
penny will land heads up or that a tossed paper cup will land openend down. Do the outcomes for the spinning penny appear to be
equally likely based on the observed frequencies?

regards to approximations of
probability and
reasonableness. (1-55)
7.SP.C.6 again focuses on
reasonableness and
approximations of probability
so questioning should reflect
these ideas. (1-66)
Having students observe
frequencies to build a nonuniform probability model
should be emphasized
throughout the lesson, as it is
reflective in 7.SP.C.7b.

of fractions and links them to
percentages. This idea will
need to be linked to
probability and is an

Big idea for students is:
although a compound event is
made up of two events
occurring, its probability is
written with one fraction in
relation to the new sample
space.
None
Find probabilities of compound events using organized lists,
tables, tree diagrams, and simulation.
Understand that, just as with simple events, the probability of a
compound event is the fraction of outcomes in the sample space
for which the compound event occurs.
