  1. Probability and Fractions By Mr. Bales

  2. Objective • By the end of this lesson, you will be able to describe probability in words and numbers. • Standard 4SDAP2.2 - Students will express outcomes of experimental probability situations verbally and numerically (e.g., 3 out of 4, or 3/4)

  3. Introduce • In this bowl, I have ten colored shapes. I have 7 blue, 2 red, and 1 yellow. • How likely is it that I will draw a yellow shape? • How likely is it that I will draw a white shape? • Fractions can be used to describe the probability of an outcome. • How many shapes are blue? • How many total shapes are in the bowl? • The probability of choosing a blue shape is 7/10.

  4. Probability as a Fraction • Find Probability • Use words and a fraction to describe the probability of rolling a six on a die. • One out of six numbers on a die is a six. Probability = number of favorable outcomes total possible outcomes Probability = number of 6’s total possibilities on die = 1/6 So, the probability of rolling a 6 on a die is 1 out of 6, or 1/6

  5. Activity • On your tables are three lunch bags with seven colored tiles in them. I will not tell you how many of each color there are, and you MAY NOT PEEK!! • On the board, you will see that the bags contain a cure for a specific celebrity that has taken ill. • It is your goal to find out which bag belongs to which celebrity. • Rules: • Start with one bag, and take turns in your group reaching in the bag and taking a shape out, noting its color on your whiteboard, and put it back in the bag. • Record the colors as they are picked on your whiteboard. • After each of you has drawn a tile or two from each bag, discuss the results. • Predict which sign you think matches the bag. • Record your final prediction for your group on the front whiteboard.
