We had to make some changes last week, due to the Map testing schedules, and our Exam has been pushed back to Tuesday of this week. After our unit exam, we will begin our probability unit. In this unit, students will extend their work with ratios and proportional reasoning to consider the probability of a random event like spinning a spinner, rolling a die, or drawing randomly from a collection. To find probabilities, they will determine the number of possible outcomes for an event, and will represent probabilities as ratios using both experimental and theoretical models.
We will interpret a probability as the proportion of the time that an event occurs when a chance experiment is repeated many times, as they develop an understanding that a probability is a number between 0 and 1 that represents the likelihood that an event will occur. We will use probabilities and proportional reasoning to estimate and predict quantities based on the number of observations of an event. As they investigate chance processes, they will observe that, while probabilities can allow them to predict likelihoods, actual results may vary from their predictions. Comments are closed.
