Writing Algebraic Expressions.OK, welcome to lesson 2. In this lesson you will learn how work with like terms. The key difference between middle and high school math is high school math requires students to understand variable expressions- i.
Of course you should expect basic algebra on the GED and knowing how to work with variables is critical. The starting point to mastering algebra is understanding how to work with variable terms and determining when terms are like and not like.
OK, we are ready to start the chapter on equations. The topic of equations could very well be one of the most important chapters of the course so really pay attention- you will need this for the GED! Distributive Property. Simplifying By Combining Like Terms.

EE Standard 6. Enduring Understanding Big Ideas : The order of operations and properties help us simplifying expressions Essential Questions: How do you know when an algebraic expression is in simplest form?
Starter: Accessing prior knowledge Which of these representations does not tell us to multiply? As they do, review the commutative, associative, identity, 0, and distributive properties. Have them get out and review their properties foldable from September, Lesson 7.
Sing the Properties Song attached to review. Lesson Segment 1: How do the order of operations and properties help me simplify algebraic expressions? In our language we often simplify expressions. For example, we could say, "Hi there. How are you doing? Or, we could say, "Hey, Sup? In mathematics we want to write expressions as simply as possible, but do not want to change their meaning or value.
We want the simplified expression to be equivalent to the original, longer expression. When we say "simplify the expression" we mean to make the expression more simple to understand or look at without changing the value of the expression. In the problems for 2 on the starter you used the properties to simplify the expressions. In problem 3, you used the order of operations to simplify the expression. As you ask the following questions to mobilize student knowledge from past lessons, have student record the problems on Smart Pals or on a paper.
When we say two expressions are equivalent what does that mean?
The equal sign tells us one expression is equivalent to the other or in other words, the expressions have the same value. If two expressions are equivalent, must they always look exactly the same? What makes you think so? How can we know whether two expressions are equivalent if they don't look alike? One way to verify that two expressions are equivalent, is to simplify each expression.
We use properties to simplify algebraic expressions. When we simplify an algebraic expression using properties, we can compare the original expression with the simplified expression to make sure they are equivalent. A simplified expression is always equivalent to the original. The way to compare the value of two algebraic expressions is to substitute values for the variable s and evaluate each as we did in our lesson a couple of days ago.
Lesson Segment 2: How do you know when an algebraic expression is in simplest form?The worksheets I developed were for certain days when I could find no resources on hand for what I wanted the students to master. These worksheets found their way into this book as well. So you can conclude that this booklet you are perusing is a compilation of ten years of supplemental writing.

Lesson Algebraic Expressions Problem set 1.Have students turn and talk about what sqrt 25 actually means. Most students will say that the answer is 5.
Push them to explain why. Then draw a picture of a square on the board and tell students that the area of the square is Have them determine the length of each side of the square. Explain to students that this is where the term "square root" comes from.
Have them determine the side length for a square with an area of Let students share their ideas and critique each other's reasoning MP3. Guide students towards the understanding that the length of the sides will need to be a little larger than 3 but will not be equal to 4. The next portion of the lesson will help students to make accurate approximations of square roots.
The idea is to first help students understand that radical expression are numbers too! By thinking about "nearby" radicals that simplify to whole numbers, students can get a decent approximation as to the quantity that a radical expression represents. This will be key in students interpreting the roots of quadratic functions that are in simplest radical form. Now that students are beginning to understand that you can take the square root of "non-perfect squares", we want to talk more about estimating.
I start with sqrt 8 and ask students to make an estimate for the value. Many students will say that the answer should be a little less than 3 around 2. Encourage students to explain their reasoning. The next example is sqrt Now I ask students to offer some ideas for this value once they realize it is between 3 and 4. I typically will get answers like 3.
I record all of these on the board and then ask students to think about which makes the most sense. I have them do a brief turn and talk to decide. As students discuss, I am listening for students who can verbalize that the answer should be 3.
We can have a similar conversation for sqrt In each case, encourage students to find the "actual" answer using the calculator to see how close they are able to get with their estimate.
Both of these slides will require a mostly "direct teaching" approach. Both techniques for simplifying radicals are skill based and require students to follow the appropriate steps. They can do this by typing the original expression and their simplified expression into the calculator and ensuring that the decimals match. This slide will allow students to practice the procedure they have just learned.
I intentionally crafted these questions to be slightly different and an extension from those the students have just seen. The idea is that students will attempt to write the expressions in simplest radical form using a common sense approach e. By using their calculator, they will know whether their attempt is correct or incorrect and they can revise their work accordingly MP1. Try not to be too helpful during this portion of the lesson. Encourage students to make a hypothesis about how to simplify the expression, test their hypothesis, and revise if needed.
I threw some unfamiliar forms of radical expressions 2, 3 in on purpose because I want student to think critically and logically about how they would simplify them MP1. Try not to be too helpful and encourage students to take risks and try to figure out how to simplify these expressions. The important point to drive home for students is that they have a calculator which will allow them to compare the decimal equivalents of the original expression and their simplification to check for accuracy!
If the decimal equivalents don't match, they can go back and try again. Encourage students to show work so that you can see their thinking. Because this is multiple choice, you will be able to grade these quickly and get good feedback on which students have grasped the day's lesson.
