Common Mistakes and Misconceptions
Students may encounter various mistakes and misconceptions while working through the practice problems in Lesson 1.3. These errors often arise due to a lack of understanding of the underlying concepts or careless mistakes. Identifying and addressing these common pitfalls is crucial for effective learning.
One common misconception is assuming that the order of operations applies only to algebraic expressions. However, the order of operations also applies to numerical expressions, which can lead to incorrect calculations. For example, a student may mistakenly calculate 3 + 4 × 5 as 23 instead of 27 because they incorrectly perform the multiplication before the addition.
Avoiding Mistakes in Order of Operations
To avoid mistakes in order of operations, it is essential to follow the correct sequence of operations: parentheses first, followed by exponents, multiplication and division (performed from left to right), and finally addition and subtraction (also performed from left to right).
Another common misconception is confusing the terms “expression” and “equation.” An expression is a mathematical phrase that represents a value, while an equation is a statement that two expressions are equal. Students may mistakenly treat expressions as equations and try to solve them for a variable, which can lead to incorrect results.
Distinguishing Expressions from Equations, Lesson 1.3 practice a answer key
To avoid confusion between expressions and equations, it is important to recognize that expressions do not contain an equals sign (=), while equations do. Expressions simply represent a value, while equations state that two values are equal.
