Using the diagram above and (your notes) their knowledge of algebraic expressions, the students will be expected to find the following: What is the linear expression that represents the length of the north side of the classroom?

Open Ended

If x = 4, what would be the length of the north side of the classroom?

Multiple Choice

The construction manager said the length of the north side of the classroom that includes the wall that joins the materials closet, the learning laboratory, and the 3-D printing station is 6x + 17. Is she correct?

• Yes

• No

Multiple Choice

How do you know?

• By observing the evidence

• By guessing

• By asking someone

• By reading a book

3. 3. In order to determine how much flooring is needed for the Maker Space, write a linear expression that represents the area of the maker space. Then, write an equivalent expression for your expression in factored form, with grouping symbols.

Open Ended

Using the diagram above and your knowledge of linear expressions, write a linear expressions that represents the perimeter of the innovative classroom?

Open Ended

Using the diagram above and your knowledge of linear expressions, find the dimensions of the learning laboratory in terms of x. (Hint: The wall lengths for the west and east side of the classroom should be equal.)

In other words - tell me what the length and width is

Open Ended

Using the diagram above and your knowledge of linear expressions, determine how far apart the couches need to be if the teachers want to place 3 evenly spaced couch areas in the corridor (large hallway area) on the other side of the wall where the 3-D printing station sits.

Open Ended

The principal of the school would like to add 2 more storage areas to the classroom on the other side of the west wall where the materials closet is, but the architecture team has determined that the outside shape of the entire classroom space needs to remain a rectangle. To assist the team, you must decide what dimensions the new classroom space must be, written in the form of a linear expression. Remember, the east and west sides of the classroom space still need to be equal. What should be the dimensions of the new classroom space?

Open Ended

First describe the length and width of your two new storage units. Then Find the area of the two new storage areas. Write your response down below.

Open Ended

Write an expression that represents the side of the classroom space with the newly added storage closets. Then, find an equivalent expression.
