This math assessment workbook offers focused practice on writing, interpreting, and solving simple algebraic expressions and equations. Students translate words into symbolic form. Other problems ask learners to substitute given values into fractions, such as 2r/4, when the value of r is 6. One-step equations involving addition and subtraction, as well as multiplication and division, appear throughout, so pupils repeatedly apply inverse operations to isolate the variable. The problems include interpreting mathematical language into algebraic expressions and solving equations for unknowns. Additionally, some problems require students to connect expressions or operations with their corresponding verbal descriptions through matching exercises. The common core skills for this unit include understanding and applying the concepts of variables and expressions, solving one-step equations and inequalities, and performing operations with whole numbers, fractions, and decimals.
