CCSS.MATH.CONTENT.4.NF.B.3.A-Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
CCSS.MATH.CONTENT.4.NF.B.3.B-Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
Historical Significance: “Probability is likely to have been started by Blaise Pascal (1623-1662) and Pierre de Fermat (1601-1665) primarily by games of chance.” (Chakravarthy) It was developed even further by the French and Russian schools.

We see probability in our everyday life, and we use it in decision making. It helps us to better understand the world around us. It is found in health and medicine, in business, economics, education, sports and engineering.

It is used at the local grocery store as they keep their shelves stocked. It is also used as your Mom figures out how much she needs to make for dinner. Probability whether we know it or not is a large part of our lives.

Today we will be learning about a statistic called probability. Probability is "the likelihood that something will happen." I'll write this on the board for you to reference. Let's take a look at this die. We're going to talk about how many numbers are on this die. Now let's talk about the probability of how likely it is we will roll a certain number. Lets practice this with a few numbers. The probability of rolling any number on a die is 1/6 since there are 6 numbers on a die. We'll be using this "Roll the Die" worksheet. Everyone will get one and a die.

You will be completing the table on this worksheet. The chance of rolling each number on a die is 1/6. Use tally marks to record how many times it takes you to roll each number once. Write each number as a fraction out of the total number of times you rolled for numbers 1-6. Now, that everyone is finished, raise your hands if you would like to share the amount of times you rolled the die for each number, and your total number of rolls.

I'm now giving you Heads or Tails worksheet for you to complete on your own using the die.
