Reflection: Intervention and Extension Simple Events - What is the probability of drawing a king from a deck of cards? - Section 2: Explore


I had a few students who really struggled to set up the ratio for simple events.  It seems to simple...but it wasn't for some!  To help with this issue, I had those particular students write out every possible outcome from every question.  For example, if we were talking about rolling a die, I had them write out the 1, 2, 3, 4, 5, and 6.  After that, I had them circle the favorable outcomes - so if we were talking about even numbers, they went back and circled 2, 4, and 6.  Then, I had them set up the ratio by counting up their circles and placing that number over the total number of things they had written down.  Though it took those students much longer to complete a problem, they were solving them accurately :)

Simple Events - What is the probability of drawing a king from a deck of cards?

Unit 9: Probability
Lesson 1 of 6

Objective: Students will be able to identify probability as being a number between 0 and 1, with 0 being impossible and 1 being certain, and calculate probability for simple events.

Big Idea: Want to win the life-sized teddy bear at the fair? After this lesson students will be able to calculate the probability of winning the bear!
