For this week's online blog assignment, please respond to the question in the following comic strip:
Since we have been introduced to variables in mathematics, put yourself in the position of the teacher. How will you respond to this student's question? In 3-5 sentences, create a response you would give this student. Keep in mind why we use letters in mathematics as this could help you in creating your response.

Reminders:
- Your response to this blog post AND another student in the class' post is due on SUNDAY, 02/26/2017 at 10pm ChST.
- Be sure to respond to the prompt FIRST, then respond to the post of another student in the class.
- Use any vocabulary terms that you've learned that could be relevant in your response
- Be creative. I will give one extra credit point (added to this online blog assignment) if your response is creative and unique.
Have fun blogging! I can't wait to read your responses!
I am Jia Li Chen from 7d and I have read Mr. Tudela Post. The reason why X coulden't be an X is because we are using it in a mathematical way which is when a number represent a unkown value because of that it is not just a letter but also equal to a number because we use it in a mathematical way which we call variables. Variables are a unkown number represent by a letter. Thats why a X coulden't just be a X because if you said why coulden't it just be a X if you are using in a mathemaitcal way then off course it should represent a number because you are explaining it in a mathematical phrase but if you just say X it off course can be just a letter because you are not using in a mathematical way.
ReplyDeletegreat job jia li! your response is understandable and accurate
DeleteExcellent response here, Jia Li! I enjoyed reading your post as it is very detailed and you provide good enough reasoning to address the concern of the student asking the question in the comic strip. Thank you for such a wonderful response!
DeleteWell 'x' have to equal to something because it is a variable. A variable is an unknown number that is represented by a letter. 'x' can be a regular x if there was a number, but instead there is no number so the 'x' have to be there to stand and represent the unknown number. Its just the mathematical way.
ReplyDeleteMarie, I am most grateful for having you indicate what "X" is in mathematics. To most students your age, it may not be clear to them exactly why we use letters in math but if you really think about it, all it means is that it stands for an unknown value. I appreciate your participation in this week's online assignment. Great work!
DeleteFirst, X is used in a mathematical way, rather than in the alphabet. The letter X is a variable. It represents an unknown value. If X didn't represent an unknown value, the expression/equation wouldn't make sense. Basically, we use letters as substitutes to help us understand it more.
ReplyDeleteDestiny I like your response because you make it more simple for me to understand and it a good response
DeleteGreat way to put it, Destiny! I like how you said "X" is used in a "mathematical way" rather than the way someone would interpret its use in the alphabet. And you are spot on with your statement that we use letters as substitutes to help us understand things more. Excellent response!
DeleteI am Emelyne Ngirutoi from 7D and I have read Mr. Tudela's post.
ReplyDeleteThe reason why X can't just be X is because your using it in a mathematical form. And another reason is because you have to find what the unknown number for the variable is when solving an equation. The last reason is that it can't just be X because you won't know what you are multiplying it with.
Emelyne, thank you for your response. I, too, agree with your reasoning that "X" cannot just be "X" because in mathematics, variables (letters) are used to represent unknown values that we must solve for. Great work!
DeleteI am Katelyn Palacios from 7D and I have read Mr.Tudela's post.
ReplyDeleteX can't just be X because it represents an unknown number called a variable. A variable is an unknown value represented by a letter. If X stands with a number it is just X (sometimes) but if X stands alone then it represents a number. When X is used in a mathematical way then it obviously represents an unknown number.
I like your explanation. It is very accurate and understandable.
DeleteI agree with u because a variable stands for a number.
DeleteI enjoyed reading your post, Katelyn! It is very important to tell the student that letters in mathematics actually helps us solve for things we do not know. As you said, X could represent an unknown number but more important, an unknown value or amount that we are trying to solve for. Thank you for your participation in this week's online assignment.
DeleteX can't just be X because in math, letters are a substitution for numbers. So it won't only be X but it will also be an unknown number. The letter X would be called a variable. The variables make us understand the problem.
ReplyDeleteCamayah, good job in explaining and it is accurate to the question
DeleteWell said, Camayah! Your post is short yet encompasses all the reasons as to why we would use letters in mathematics. It is a very good thing that you were able to define the term "variable" in your post because defining the term for the student can really help him/her understand the concept of letters in mathematics. Great job!
DeleteI am Marinel Falalimpa from 7D and I have read Mr. Tudela's post.
ReplyDeleteX can't just be X because it is a variable. A variable is an unknown value represented by a letter. So if X is by itself it is representing a number. But if it stands with a number then it is just X. In the mathematical world letters are part of the equation.
Excellent response, Marinel! I agree with the majority of your post, but just recall that if the variable X stands with a number in a mathematical expression or equation, it is NOT just X because it still represents an unknown value. As long as you have a letter in mathematics, it should always represent something or an unknown value. Thank you for your participation in this week's online assignment.
Delete{I am Franchezca from 7D and I have read Mr. Tudela's post}
ReplyDeleteX wouldn't have any purpose if it hadn't equal to something. In math, X is a variable, variables are letters that equal to an unknown number. The x in the equation is important since it would let you know what the unknown number is since you would figure out the variable that has been given to you.
I like your way of thinking here, Franchezca! It is really nice to see that you are able to make sense of the purpose for having letters in mathematics. I enjoyed reading your post and that I believe you are on the right track when it comes to understanding variables in mathematics. Excellent work!
DeleteIf I was the teacher i will tell them that x is a variable, because variables are letters that equal to an unknown number.X in the equation is important since it will let you know whats the number.They give u an variable because it represent a number.
ReplyDeleteSuperb explanation here, Floyd! What I liked the most about your post is how you stressed the importance of the variable "X" in an equation. It is very important that when answering a student's question, you tell them WHY it is important for them to learn so that there is a purpose in teaching the content. Excellent work here!
DeleteYou can't just make "x" by itself. It represents an unknown value, so it has to equal the unknown value. If it didn't represent a unknown value, the equation or mathematical expression would just make no sense.
ReplyDeleteGreat thinking here, Naleina! I completely agree with you and how you were able to see the true meaning of "x" in a mathematical equation. It is very important that students know HOW and WHY we use letters in mathematics which ultimately comes down to the fact that these "letters" have to mean something. Great response!
