## Objective

Students will be able to solve probability problems.

#### Big Idea

Students get a chance to put it all together – can they make sample spaces and calculate probabilities….we will see!

## Launch

10 minutes

OpenerAs students enter the room, they will immediately pick up and begin working on the opener – Instructional Strategy - Process for openers.  This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is mathematical practice 3.

Learning Target: After completion of the opener, I will address the day’s learning targets to the students.  In today’s lesson, the intended target is, “I know that probability is a number between 0 and 1; I can determine the probability of simple and compound events; I can use experimental probability to make predictions; I understand that experimental probability gets closer to theoretical probability as more trials are completed.”  Students will jot the learning targets down in their agendas (our version of a student planner, there is a place to write the learning target for every day).

Probability Review Explore Narrative This review requires students to create sample spaces (MP 4, 5), work together and reason through problems (MP 1 and 3), and be precise (MP 6).  Some students will be able to determine compound probability without the use of models, as they have recognized the repeated reasoning that takes place in the problems (MP 7).

## Summarize

2 minutes

As a summary to this lesson, I am going to open the floor for a class discussion on any questions students may have regarding probability and the test on the following day.  I want to ease their minds, and lead them in the right direction for studying!
