 # Bull’s Eye Math

## Bull’s Eye Math

CRA Description :
Students are asked to use their knowledge of circles, area of circles, and sectors to calculate probabilities found in games that involve circular targets and to design a target.
Subjects:
Mathematics
Geometry
Mathematical Models with Applications
Key Concepts and Terms:
Area
Concentric Circles
Diameter
Geometric Probability
Radius
Sector
Prior Knowledge:
Students should understand the concept of geometric probability. Students should be able to find the area of a circle and parts of a circle such as regions created by concentric circles and sectors.

### Bull's Eye Math

This is a great activity for my geometry students. Many of my students are avid hunters, so anything related to hunting or archery is a huge bonus. The presentation of this information allows the students to relate the material into a format that they can appreciate. Since the majority of my students are hunters, and have a good understanding on the bulls-eye, I won't need to modify this assignment much (if at all).

### It's great when our lessons

It's great when our lessons actually relate to our students' lives.  I hadn't thought of this angle with the hunters in the classroom.  Awesome.

### Bull's Eye Math

Introduction of probability is a key feature of this lesson.  Beginning in 2015-2016 Geometry will include a Probability strand which expand the knowledge of students to context other than Geometric Probability, which makes this a valuable lesson for the coming academic year.
Conics are moving from Algebra II - an algebraic view of circles will move to Geometry, and the remainder will move to Precalculus.  This lesson would be applicable for that strand, also.

### I didn't realize probablilty

I didn't realize probablilty was moving into Geometry next year.  Thanks for that information!

### Resembles an AQR lesson.

In AQR we are doing a unit on probability in games and will be having a game playing day next week to gather experimental probability since we calculated theoretical probability last week. I would like to keep this in mind for next year to add as an additional example in that unit.
