UNDERSTANDING THE STANDARD
- A spirit of
investigation and experimentation should permeate probability instruction,
where students are actively engaged in investigations and have opportunities to
use manipulatives.
- Investigation of experimental probability is continued through informal activities, such as dropping a two-colored counter (usually a chip that has a different color on each side), using a multicolored spinner (a circular spinner that is divided equally into two, three, four, six or eight parts where each part is filled with a different color), using spinners with numbers, or rolling random number cubes.
- Probability is the chance of an event occurring.
- An event is a possible outcome in probability. Simple events include the possible outcomes when tossing a coin (heads or tails), when rolling a random number cube or when spinning a spinner.
ESSENTIALS
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to
- Conduct
probability experiments using multicolored spinners, colored tiles, or number
cubes and use the data from the experiments to predict outcomes if the
experiment is repeated.
- Record the
results of probability experiments, using tables, charts, and tally marks.
- Interpret the results of probability experiments.
- Predict which of two events is more or less likely to occur if an experiment is repeated.
