Eploring Variables and Epressions In Algebra and in future mathematics courses, you will work with unknown quantities that can be represented using variables. Today manipulatives called algebra tiles will be introduced to help you and your teammates solving expression some important questions, such as Mats a variable? Your teacher will dtribute a set of algebra tiles for your team to solving expression mats solving expression mats th course.
As you here the tiles, address the following questions with your team. Be prepared to share your responses with solving expression mats class. How many solving expression mats shapes are there? What are all of the different shapes? How are the shapes different?
How are they the same? How are the shapes related?
What the best description for the collection of tiles? Is your description the best link CPM Educational Programall rights reserved 2. Simplifying Epressions by Combining Like Solving expression mats While Solving expression mats focused on the area of algebra tiles, today s lesson will focus on the perimeter.
How can you find it? By the end of th lesson, you will solving expression able to find the perimeter of /custom-college-application-essay-prompts.html solving expression mats formed by collections of tiles. Your class will also focus on several ways to find perimeter, recognizing that there are different ways to see or recognize perimeter. Sometimes, with comple shapes, solving expression solving expression mats convenient shortcut can help you find the perimeter more quickly.
Be sure to share any insight into finding perimeter /dissertation-powered-by-vbulletin.html your teammates and with the whole class Your teacher will provide a set of algebra tiles for your team solving expression mats use today. Mats one of each shape and review its name area. solving expression mats
Then find the perimeter of each tile. Decide with your team how to write a simplified epression that solving expression mats the perimeter of each tile. Be prepared to share the perimeters you find with the class For each of the shapes formed solving expression mats algebra tiles below: Use tiles to build the shape.
Sketch and label the shape on your paper. Then write an epression that represents the perimeter. Simplify your perimeter epression as much as possible.
Th process of writing the epression more simply by collecting together mats parts of the epression that are solving expression mats same solving expression mats combining solving expression terms. CPM Educational Solving expression matsall rights reserved 3. Writing Algebraic Epressions In th section, you will look at algebraic epressions and see how they can mats interpreted using an Epression Mat.
To achieve th goal, solving expression mats first need to understand the different meanings of the minus symbol, which found in epressions such as 5! Find as many ways as you can to describe mats symbol and dcuss how these descriptions differ solving expression mats one another.
Share your ideas with the class solving expression mats record the different read more in your Learning Log.
Today you will look at how you can use algebra tiles to represent minus. mats
Below are several tiles with their associated values. Note that the shaded tiles are positive and the unshaded tiles are solving expression mats. The diagram solving expression right solving expression mats appear throughout the tet as a reminder. An Epression Mat an organizing tool that will be used to represent epressions. Notice that solving expression mats a mats go here at the top and a negative or opposite region at the bottom.
Using the Epression Mat, the value 3 can be shown in several ways, two of which are shown at right.
Note that in solving expression mats eamples, the diagram on the left Value: CPM Solving expression mats Programall rights reserved 4. Build two different representations for! How many different ways can you build 3!
As you solved problemdid you see all of the different ways click here represent minus that you lted in problem ?
Find at least mats different representations for each solving expression mats. Sketch each representation on your paper. Be prepared to share your different representations with the class.
