Write an algebraic expression that represents the area of the flag

Some pairs will have the same expression but they are unlikely to come up with the same scenario. At the end of the day they had 4 rolls and 3 pieces left. They produced 5 rolls less 2 pieces that day. Since it represents a number, you treat it just like you do a number when you do various mathematical operations involving variables.

The test will be one tool that will help determine how well students understood the material. When they receive their feedback from other students they may choose to make changes before saving their work.

A good witch by the name of Mrs. The test is a document that is loaded either on their e-mate computers or accessible from the computer lab. Value of an Expression When you are asked to find the value of an expression, that means you are looking for the result that you get when you evaluate the expression.

For example, the area of a rectangle is length times width. This allows the teacher a chance to access their work later to add comments and questions and to assess for understanding.

The remainder of the test will be checked for correct answers. How much did they sell of their new flavor? Make sure they can explain their answers.

The first two questions will be assessed using a rubric. Students access the test, type their answers in, print the test when they are finished and then hand it in. The store started the day with 5 crates of bananas less 1 bunch. The students must explain what the variable represents, write the algebraic expressions, perform the operation and state what the solution means for each problem.

Again this allows the teacher a chance to access their work to add comments and questions and to assess for understanding. Students will use an on-line assessment to give them feedback on their understanding. You are allowed to pick out a video game console for you and for some of your friends.

This is the scenario: Well, not every rectangle is going to have the same length and width, so we can use an algebraic expression with variables to represent the area and then plug in the appropriate numbers to evaluate it. Have students explain each part of the problem and what the solution represents.

The test focuses on the essential questions of the unit and asks students to demonstrate their new skills in working with algebraic expressions. Glanzer wants to reward you for your acts of generosity. Have students beam their scenario to two other pairs of students.

Pose the following question: At the beginning of the year the custodian noted that we had boxes plus 22 rolls of toilet paper. They produced 4 rolls and 5 pieces of buttered popcorn flavored candy during the day. If a given rectangle has a length of 4 and width of 3, we would evaluate the expression by replacing l with 4 and w with 3 and multiplying to get a value of 4 times 3 or Remind students that it may be a good idea to take notes in their Discovery Journals as they shop.

Try this subtraction problem together: So keep in mind that vary means to change - a variable allows an expression to take on different values, depending on the situation. You will be given the websites from which to shop. The students will participate in a virtual shopping trip for their friends.

Each pair should then read through the other scenarios and type comments or questions about the scenario and beam them back to the original creators. Documentation can be kept on a PDA. Glanzer will not tell you how many friends you can include.

Students must be familiar with the Hot Dog Stand software prior to this activity. The Candy Shop has 6 rolls of mint candy plus 4 pieces when the store opens.mi-centre.comtEE.B.6 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

Write an expression to show the total area of the 3 fields in terms of their side length s.

2. Evaluate your expression to find the total area of the fields if they each measure mile on a side. A. It takes Ben 40 minutes to mow each field on the farm.

1. Write an algebraic expression to represent the time that Ben spends mowing f fields. 2. The expression 9 + x represents a value that can change. If x is 2, then the expression 9 + x has a value of If x is 6, then the expression has a value of So 9 + x is an algebraic expression.

In the next few examples, we will be working solely with algebraic expressions. Example 2: Write each phrase as an algebraic expression. 1 Solving Linear Equations Solving Simple Equations An equation is a statement that two expressions are equal.

A linear equation in one 2. Make a Plan Use a verbal model to write an equation that represents the problem. = −.

Grade 6 » Expressions & Equations

Use algebraic expressions to solve the following problems: 3. Create a story that could mean the same as the expression 2x – 1. Make sure to state what the variable is representing. 4. Write an expression that would mean the same as having 4 full rolls of strawberry candy plus 3 more pieces.

5. Variables and expressions instructional activity are explored by using algebra tiles to model each algebraic expression. Middle schoolers will then write a numerical expression to represent each phrase and complete two test prep questions for variables and expressions.
