Welcome to

This website was created to assist both students and parents in Mr. Ritter's classroom.  Below you can learn a little about me and find information about my classroom rules, my grading policy, and the high school's calculator and test policies.

Homework assignments can be found on the calendar by clicking on the individual class pages to the left.

A Little About Me 


I grew up in Bethlehem and have lived in the Lehigh Valley my entire life. I married my wife, Sarah, in 2006, and we welcomed our son, Ryan, in 2009. We currently have two pets, a rescued rottweiler-shepherd mix named Baxter and a cat that showed up on our doorstep one night, Mittens. Other than spending time with my wife and son, I enjoy golfing. I competed in track & field in high school and college where I held two high school records (long jump and 200 meters) and one collegiate record (4x200m relay), but I found that golf is more fun at this point in my life! I was a track and field coach at Salisbury High School for 8 years and the JV golf coach at Emmaus for 6 years before deciding to take time away to embrace the world of parenthood. Since 2015 I am coaching youth soccer.

Some assorted favorites of mine include: the New England Patriots; the Penn State Nittany Lions; Arsenal FC; playing fantasy sports; watching NFL football, PTI, Homeland, Game of Thrones, and the Big Bang Theory; golfing; playing poker; chess; Playstation (online too); listening to music; and traveling. Currently, I have set foot in 11 countries and 30 states with the goal of someday setting foot in all 50. Disneyland/World are my favorite vacation destinations!


Classroom Rules and Procedures


Be Respectful. Students' classroom behavior and comments should show respect for fellow students and teacher. (This means no inappropriate language.)

Be Prepared. Bring your covered textbook, notebook, writing utensil (preferably pencil), homework and calculator for EVERY class unless instructed otherwise.

Be On Time. If you are going to be late, make sure you get a pass. All lates will be reported. Remain in your seats until you are dismissed. The bell does not rule!

Be Efficient. Use your class time wisely. When I allot time for you to work on assignments, I expect you to do so. This gives you an opportunity to ask questions.

Be Honest. Cheating is a serious offense and will not be tolerated. Also, copying of homework is a form cheating and all parties will be punished accordingly.

ALL school rules apply!


Grading Policy

 An essential element of learning math is practicing problems. Homework will be assigned regularly and will be checked for points. It is extremely important that homework is completed each time it is assigned. Homework is usually worth 2 points, but can be worth more for larger assignments. There is NO credit for late homework!

Quizzes will vary in point value. Quizzes will almost always be announced.

Tests will be given throughout each marking period with point values greater than quizzes. You will be given advanced notice for all tests.

In addition to the aforementioned, I also give a 30-point class preparedness grade. Points can be lost for things such as not participating, books not being covered, arriving late, unexcused absences, etc.

Extra credit and bonus points will be given throughout the year. Students should take advantage of the chances when they arise.

Except for Algebra I CP, grading is based on a point system. All points earned throughout the marking period from homework, quizzes, tests, etc. will be totaled. To find your grade, divide your total points by the total points possible.

Per East Penn policy, Algebra I CP grades will be weighted as follows: 50% Tests, 10% Study Island, 10% Homework, 30% everything else (quizzes, participation, projects, etc...).

EHS Calculator and Test Policies


All mathematics courses at Emmaus High School allow the use of calculators on a daily basis. There are three basic kinds of calculators on the market:

  • Four function ( +, -, x, ¸,=)
  • Scientific (sin, cos, tan, ln, log, exp, , 1/x, nPr, nCra b/c)
  • Graphing (statistics, matrices, graphing)

Four function calculators are primarily used in elementary school. Scientific calculators are satisfactory for students taking Algebras I and II, Geometry (all levels), and Math Analysis. Graphing calculators are used in many classes occasionally, but Algebra III/Trig, AP Statistics and Calculus involve their regular use. The AP Calculus and AP Statistics courses are designed with graphing calculators as an integral part of the curriculum. The TI-83, TI-83 plus, or TI-84 is recommended for AP Statistics and AP Calculus.

Although the TI-89 and graphing calculators with Computer Algebra Systems (CAS) are allowed on SATs and portions of the AP Calculus exam, they may not be used in testing environments in Emmaus high school math courses or on Keystones Exams. Our courses emphasize developing algebra skills and understanding in preparation for many colleges’ math and science courses that do not allow calculator use.

We expect students to purchase their own calculator as a needed school supply along with pencils, notebooks, and a backpack. Students become more familiar with calculators when they consistently use the same type at school and home.

The math department will issue a calculator (as they do textbooks) to any student who cannot purchase one for financial reasons. 


All unit tests and common assessments may not be taken home by students. Any student/parent may request to see a test in the presence of the student’s teacher or in the Guidance Office at a mutually agreed upon time. The use of calculators for tests is at the discretion of the teacher based on the material being tested.
