Do they place the number and variable in the correct places?

I am looking for students to share that the amount of money increases as more visitors come. Students work to complete the table independently. What does the variable represent given the context of the problem? How did you know what operation to use? Students are using MP3: For number 3, some students struggle and mistakenly use subtraction in lesson 18 writing and evaluating expression expression.

For each visitor that comes to the farm, they collect how much money? I ask questions to the class before moving on. Then how can we represent the amount of money they will collect if there are n visitors?

What operation is happening between this value and variable? I ask for students to brainstorm with their partner about what the point 0, 0 represents.

What does the constant represent given the context of the problem?

If students correctly answer problems on page 5 they can move onto page 6. Once most students are finished, we come together to share what we notice. We move on to page 4. How does your expression represent the number of dimes Ella has? I may ask them these questions?

I want students to connect the operation they are using to answer questions with numbers to the expression. If students are struggling I may ask them the following questions: As they work, I circulate around the classroom and check in with each group. Students create the graph independently using the table they created on page 3.

Reason abstractly and quantitatively and MP4: I ask for different ways to write the expression switching the order of the number and variable, using a dot, using parentheses, using 8n.

As they are working, I am looking specifically at problems 4 - 7. JPG In this lesson students will set the foundation for the next two lessons where they are writing expressions and equations to model situations and then using those equations to answer further questions.

They may notice that, like the table, the amount of money collected is increasing as the number of visitors increases.

What amount are you starting with? For number 6, I check that students know what to do when they see the fraction bar. Students do not learn to perform integer operations in 6th grade, but students will be suspicious that something is wrong because of the order of their terms. I want to discuss that addition is commutative, and either expression will work.

If I see things like 12 - 6 for Problem 4 or 10 for Problem 5, then I know that students are not thinking about using an unknown and are using their actual ages.

Some students will not read carefully, and will not use a to represent their age now. How much money would they collect if there were 6 visitors? I am looking for them to articulate that 0,0 shows that if there are no visitors, the farm will not collect any money.

I am also looking to see that they use the order of operations correctly. Problem 23 will confuse some students, because the expression will be 6 - I am looking for: Are scholars correctly translating the verbal expression into numerical form?MATHEMATICS CURRICULUM 6Lesson 18 •4 Lesson Writing and Evaluating Expressions MATHEMATICS CURRICULUM 6Lesson 18 •4 2.
