Religion Curriculum
  
Part 1.  Philosophy of Religion:
God’s Word is the only source of knowledge for salvation.  It is God’s desire that “all are to be saved” (I Timothy 2:4) and that His Word be taught to all creatures (Matthew 28:19).  It is, therefore, the primary responsibility of St. John’s Lutheran School to teach God’s Word in its truth and purity.
 
Part 2.  Exit goals for graduation:
It is our prayer that our religion curriculum reaches the following goals for each child.
 

1. The child realizes that he is a sinner and needs God’s love.
2. The child realizes that God, in His love for sinful man, sent His Son as Savior.
3. The child realizes that God’s Word, as contained in Holy Scripture, is the only source of Christian truth.
4. The child learns that he has the sole responsibility of practicing his Christian faith in the world.
5. The child learns how to pray and for what to pray.
6. The child is prepared for communicant membership in the congregation.

Introduction and RationalePhilip’s
 
The study of mathematics is important to help students recognize the orderly way God created our world and how in that same way he allows numbers to work perfectly together as calculations are performed. Knowledge of mathematics is essential to be a productive citizen. St. John's is committed to offering students a high-quality mathematics education so they are prepared to be leaders in the church, school, and community.
The study of mathematics also provides every student with the opportunity to choose among the full range of future career paths. Mathematics trains the mind to be analytic - providing the foundation for intelligent and precise thinking.
To compete successfully in the worldwide economy, students must have a high degree of comprehension in mathematics. More than that, however, mathematics is critical for all students, not only those who will have careers that demand advanced mathematical preparation, but all citizens who will be living in the twenty-first century. These standards are based on the premise that all students are capable of learning rigorous mathematics and learning it well. Proficiency in most of mathematics is not an innate characteristic; it is achieved through persistence, effort, and practice.

The standards focus on essential content for all students and prepare students for the study of advanced mathematics, science and technical careers, and postsecondary study in all content areas. All students are required to grapple with solving problems; develop abstract, analytic thinking skills; learn to deal effectively and comfortably with variables and equations; and use mathematical notation effectively to model situations. The goal in mathematics education is for students to:

• Develop fluency in basic computational skills.
• Develop an understanding of mathematical concepts.
• Become mathematical problem solvers who can recognize and solve routine problems readily and can find ways to reach a solution or goal where no routine path is apparent.
• Communicate precisely about quantities, logical relationships, and unknown values through the use of signs, symbols, models, graphs, and mathematical terms.
• Reason mathematically by gathering data, analyzing evidence, and building arguments to support or refute hypotheses.
• Make connections among mathematical ideas and between mathematics and other disciplines.
•  

The standards identify what all students should know and be able to do at each grade level. The standards emphasize computational and procedural skills, conceptual understanding, and problem solving. These three components of mathematics instruction and learning are not separate from each other; instead, they are intertwined and mutually reinforcing.

a.Evaluate the reasonableness of the solution in the context of the original situation.

b.Note the method of deriving the solution and demonstrate a conceptual understanding of the derivation by solving similar problems.

c.Develop generalizations of the results obtained and the strategies used and apply them to new problem situations.

Grade Eight        
By grade eight, students' mathematical sensitivity should be sharpened. Students need to start perceiving logical subtleties and appreciate the need for sound mathematical arguments before making conclusions. As students progress in the study of mathematics, they learn to distinguish between inductive and deductive reasoning; understand the meaning of logical implication; test general assertions; realize that one counterexample is enough to show that a general assertion is false; understand conceptually that although a general assertion is true in a few cases, it is not true in all cases; distinguish between something being proven and a mere plausibility argument; and identify logical errors in chains of reasoning.
Mathematical reasoning and conceptual understanding are not separate from content; they are intrinsic to the mathematical discipline students master at more advanced levels. Students use their God-given, logical minds to examine these things and to develop an appreciation for how God created our world in such an orderly way. They also recognize how God allows us to use numbers to perform various calculations and appreciate how numbers work.
 
Algebra
 

1. Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable:
   1. Students use properties of numbers to demonstrate whether assertions are true or false.

 

2. Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root, and raising to a fractional power. They understand and use the rules of exponents.
3. Students solve equations and inequalities involving absolute values.
4. Students simplify expressions before solving linear equations and inequalities in one variable, such as 3(2x-5) + 4(x-2) = 12.
5. Students solve multistep problems, including word problems, involving linear equations and linear inequalities in one variable and provide justification for each step.
6. Students graph a linear equation and compute the x- and y-intercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).
7. Students verify that a point lies on a line, given an equation of the line. Students are able to derive linear equations by using the point-slope formula.

24. Students use and know simple aspects of a logical argument:
    1. Students explain the difference between inductive and deductive reasoning and identify and provide examples of each.
    2. Students identify the hypothesis and conclusion in logical deduction.
    3. Students use counterexamples to show that an assertion is false and recognize that a single counterexample is sufficient to refute an assertion.
25. Students use properties of the number system to judge the validity of results, to justify each step of a procedure, and to prove or disprove statements:
    1. Students use properties of numbers to construct simple, valid arguments (direct and indirect) for, or formulate counterexamples to, claimed assertions.
    2. Students judge the validity of an argument according to whether the properties of the real number system and the order of operations have been applied correctly at each step.
