Welcome

On this blog my students will be introduced to ways of using math and other skills taught in the classroom that show them how you are able to apply them in everyday life. Everyday life for me is archery a sport that I have educated myself about and have had great passion to try and introduce it to students. Archery is not something new by any means but is something that is being reintroduced to newcomers now more than ever. This blog will also discuss the NASP program and its benefits in the schools. And hopefully by the throughout this blog you will grow to have love for archery and see the impact that is has still today.

Helpful Tips Before You Blog

When blogging there are a few reminders that you should remember before you hit that post button. Those that will be allowed to view this blog are only Sparta High School students in my class. I want you to remember that those you will be responding to are your peers and with that being said I want you to respond how you feel but in a way that is respectful to others and their opinions. The other main thing to remember is that you need to use your own work and thoughts and not copy and paste or in essence steal. You also want to remember not to use items that are copyrighted. In simple terms I want my students to use the golden rule treat others as you would want to be treated.

Calculating arrow Front of Center (FOC)


This formula is used by all types of archers from hunters, target, and 3-d archers to help figure if the arrow flight is where it should be. There are different opinions on the where it should be take this formula and diagram to aid you in testing several different arrows at different FOC. Decide which one would be the best arrow for using at long distances. Then post your finding and why you feel that percentage is the best.

1) Measure the length of the shaft from the throat of the nock to the end of the shaft, excluding the insert; this is length “L”

2) Using a sharp edge, balance the arrow (including the point) and mark the balance point

3) Measure the distance from the throat of the nock to the balance point; this is length “B”

4) Input B and L into the following formula:FOC%=(B/L-0.5)*100
