Seventh graders learn to put a number on chance, from 0 for impossible to 1 for certain, and to calculate the probability of simple events like a coin flip or a dice roll.
Students will be able to…
From weather forecasts to board games, we constantly judge how likely something is. How can we turn 'maybe' into a precise number?
Project this and answer each question about how likely events are — read the explanation after each one.
Tap any phase to open the teacher moves and student actions.
A forecast says 70% chance of rain. What does that number actually mean?
Students answer questions about chance.
Students find probabilities of simple events.
Students build a spinner to match probabilities.
Students reflect on the probability scale.
Aligned to the Common Core State Standards for Mathematics.
Understand that the probability of an event is a number between 0 and 1 expressing likelihood.
Approximate the probability of a chance event by collecting data and observing long-run relative frequency.
Develop a probability model and use it to find probabilities of events.
Model with mathematics.
