(4) Algebraic reasoning. The student applies mathematical process standards to develop concepts of expressions and equations. The student is expected to:
- (A) identify prime and composite numbers;
- (B) represent and solve multi-step problems involving the four operations with whole numbers using equations with a letter standing for the unknown quantity;
- (C) generate a numerical pattern when given a rule in the form y = ax or y = x + a and graph;
- (D) recognize the difference between additive and multiplicative numerical patterns given in a table or graph;
- (E) describe the meaning of parentheses and brackets in a numeric expression;
- (F) simplify numerical expressions that do not involve exponents, including up to two levels of grouping;
- (G) use concrete objects and pictorial models to develop the formulas for the volume of a rectangular prism, including the special form for a cube (V = l x w x h, V = s x s x s, and V = Bh); and
- (H) represent and solve problems related to perimeter and/or area and related to volume.
