# 4-1 evaluating and writing algebraic expressions

Expressions that are not poly expressions are standalone expressions. Standalone expressions are expressions of the forms above when determined not to be poly expressions, as well as all expressions of all other forms. Fluently add and subtract multi-digit whole numbers using the standard algorithm. Grade 4 Arkansas 4. Use this principle to recognize and generate equivalent fractions. Recognize that comparisons are valid only when the two fractions refer to the same whole. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole. Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation.

Add and subtract mixed numbers with like denominators, e.

Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e. Solve word problems involving multiplication of a fraction by a whole number, e. Between what two whole numbers does your answer lie? For example, rewrite 0. Recognize that comparisons are valid only when the two decimals refer to the same whole.

Represent verbal statements of multiplicative comparisons as multiplication equations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1 — is a multiple of a given one-digit number.

Determine whether a given whole number in the range 1 - is prime or composite. Identify apparent features of the pattern that were not explicit in the rule itself. Explain informally why the numbers will continue to alternate in this way. Grade 4 Arkansas 5. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond e.

Grade 5 Arkansas 5.Practice plugging in values to evaluate real-world algebraic expressions. These are introductory problems, so the expressions aren't too complicated.
