Complete the table and answer the questions below. Write an expression describing her earnings for working H hours. Show Step-by-step Solutions Problem Set 1.

The lesson may be adapted to meet the needs of your students by using the suggestions in the Extension section. Specific suggestions are provided to support students who may need additional practice in evaluating expressions, and the Expansion section provides additional challenges for students who are ready for a challenge beyond the requirements of the standard.

The lesson helps students understand the need for the order of operations. The lesson focuses on evaluating expressions with no grouping symbols. This prepares students for using the order of operations to evaluate expressions with multiple grouping symbols in Lesson 2. Distribute a copy of the A Lesson from Aunt Sally practice worksheet to all students.

About "Writing and evaluating expressions" Writing and Evaluating Expressions: In this section, we will learn, how to write a mathematical expression from a verbal description and evaluating expressions for the given values of the variables or unknowns.

Jeremiah has to find the value of these expressions: This will help us understand why Jeremiah and Aunt Sally get different answers. First, Jeremiah needs your help. Work together in pairs to find the value of these expressions. The second column will be used later. Do all students evaluate these expressions performing the operations strictly from left to right?

This is what we would expect. Students read left to right, so they tend to also want to perform the operations from left to right. Yet, some students may first perform the operation they perceive to be the easiest.

While you are observing, make note of any students who get these same answers. You may want to call on them to ask about the process they used when the class discussion of these solutions occurs later in the lesson.

Note, only write the values of the expressions Jeremiah and Aunt Sally computed, as noted in boldface. Do not write the processes shown in the table. They are provided for use in class discussion.

For each expression, work together in pairs again to understand how both Jeremiah and Aunt Sally got their solutions. To do so, follow these steps: Try to understand the solution you did not have.

Be prepared to share your thinking with the class. The purpose is to help students understand that performing the computations in different orders results in different solutions.

This activity will motivate the need for an order of operations that all agree on. Write each expression on the board.

Ask students to write the processes Jeremiah and Aunt Sally used for each expression on the board. Then ask students to explain the processes used by both Jeremiah and Aunt Sally.

Next, introduce students to the order of operations. This is a specific order used so everyone is sure to get the same value. Today we will use the order of operations to decide whether Jeremiah or Aunt Sally got the correct solutions for each expression.

As shown, it may be helpful to have students circle the operation they should perform at each step. Not all students will need to use circles, but it helps some students to focus on a single task during each step. There are no Parentheses or Exponents in this expression.Writing Expressions The most important part of writing expressions is to know that words for addition, subtraction, multiplication and division.

It is also important to know "turn around" words and words that indicate the use of parenthesis. Multiplication, division and remainder are said to be on the same level of precedence.

Addition and subtraction operations are evaluated next. If an expression contains several addition and subtraction operations, evaluation proceeds from left to right.

2. Multiplication of Algebraic Expressions. Many students confuse this idea and it's not surprising because sometimes the way we write math is not consistent. Division of Algebraic Expressions.
