The Counting Principle In Class Worksheet and Homework Questions

Helped me during my classes. Fun and engaging to students. Thank you so much for this!

My students enjoy this to reinforce concepts we were studying in class. Thank you.

My students loved this resource! It easily fit into my lesson. Thank you for the resource!

It's a good resource that works well to establish sample space as a concept and to explain methods of both listing and reasoning out sample spaces. It did a really thorough job of explaining different types and can be used in both introductory classes and for permutations + combinations lessons. Teachers should be alerted that the answer key has some issues; due to repeated outcomes, such as "ham + turkey" being the same as "turkey + ham," the situations listing multiple meats or veggies should actually be divided by k! (k being the number chosen). That is, those should be using combinations, not permutations (which is what the key is using). For example, the "2 meats" situation should be divided by 2, while "3 veggies" should be divided by 6. This should not have any effect on the student sheets, which can be used as-is. This could also be explained away to younger students if one considers ham + turkey to be different from turkey + ham, such as "a veggie for the top, middle, and bottom in order" or "a hot meat and a cold meat," which would allow for the answer key to be correct. The students found it relevant to life and helpful for identifying where sample spaces come from.

Clearly written and easy to follow. I was so glad to see the answer sheet was added.

This is perfect just what I've been looking for to help our students!

This worked great!

awesome!
