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!
well sinc x is a variable and included in a algebric expression it would have to equal something because if you didnt include it you would get a wrong answer for the question
ReplyDeleteI agree to what you stated, Devin. X always has to have a value because if it doesn't then you wouldn't be able to get an answer to a problem.
DeleteThank you for your response, Devin. I, too, agree with your statement. Good job.
Deletewhich is why the x must equal something unless theres something else in the problem
ReplyDeleteX always has to represent a number in order to answer the problem. So for example if X doesn't have a value then you wouldn't have an answer for your problem. In other words, X it won't be possible for you to get an answer.
ReplyDeletei also agree with your explanation.
Deletegood job nate i also agree with your comment...
DeleteI agree with what you stated. You really do need the value of a variable to answer an equation. NICE JOB👌👌
DeleteNathanette, I appreciate your careful attention to the importance of the value of "x" in this context. Awesome work!
Deletehow i would explain to a student is by telling them that sometimes we use letters as a name for a number.We also use it to substitute a number.We could even use it as explaining it on how to find a or the answer.
ReplyDeleteExcellent explanation, Dora. Although you are spot on with the concept of the comic strip's example, it would have been nice to know what letters in mathematics are called (variables). Aside from that, thank you for your participation in this week's online assignment.
DeleteX is a variable that always has to represent an unknown number or it can be next to a number. So if you have a question like 3(3x+2) it will be 9x + 6.
ReplyDeleteNice explanation and use of an example here, Alicia! Thank you for pointing out to the student that "x" is a variable. Excellent use of vocabulary!
DeleteX have to always equal something in order to answer your problem into a correct answer so X is also a substitute variable next to your problem.X is always in every mathematical problem to solve your work.
ReplyDeleteI also agree with you too :)
DeleteGood job explaining this concept, Neinarin. I appreciate your explanations in this post. Good work.
DeleteI know that X represents a number that answers the problem to the question. An example is the variable "X" doesn't have a value that wouldn't answer to the questions. other variables cannot be a answer to an equation.
ReplyDeletei also agree to you ramona what you said abou the qustion.
DeleteWhat are the other variables that cannot be answer to an equation and what do you mean?
DeleteThank you for your response, Ramona. To add onto Jevony's comment, remember, there can be more than one variable in an equation, however, for the purposes of 7th grade mathematics, we will only be studying mathematical equations that contain just one variable. Awesome work!
Deletethe letter always has to represent a a number in order to answer the math problem like for example your looking for the letter x you dont have too answer the value.
ReplyDeleteI enjoyed reading your response, John Paul. Yes, the letter in a mathematical equation has to represent a number in order to answer any given problem. Good thinking here!
Deletex is a variable which means it is a letter that represents an unknown number. so like this x+6=12 you want to find the number that is going to equal to twelve so you want to find x okay so -6 and -6 can't so 12-6 right, gives you six so then, x=6 and thats why letters are important its like a number that you have to find.
ReplyDeleteChristian, thank you for your detail and thoughtful response. Since you assumed the role of the teacher, I appreciate how you provided an example to show them how a variable is used in mathematics. Excellent work!
DeleteWhy cant "X" just be "X"?
ReplyDelete"X" is a Variable."X" is a Variable that represents the unknown in a problem if you know what I mean. Sometimes "X" cant be just "X" because you need the "X" to solve your problem so that you can have your answer.The "X" can help you.
Why does it always have to equal something?
Well its because the "X" represents the unknown:W
What a thoughtful and good explanation, Jevony! I really like how you were able to write your response in a fashion that could be best understood by the student in the comic strip. Good job!
Deletex represents a unknown number, and why can't X just be x why does it have to be representing a thing. It represeting a thing so we can solve it in many different ways or for a unknown value. Ex: x+11=12 so we take 11 and substarct it to 12 then u get 1. So X= 1
ReplyDeleteGreat response, Cindy! I noticed you were able to pose a question and then later provide a detailed explanation as well as an example. Nice work!
DeleteX can't just be x because you can't subtract or multiply or divide or add X to another value and get an end answer. If you multiply X by, let's say, 4, you would get 4x. Which would count as a product but not really an end product, simplified product. You would still have to multiply X by 4 to identify the final product. If the final product was 28, the X would have a value of 7, which would make a full equation instead of 4x=28.
ReplyDeleteInvolving this in real life is quite simple. Let's say your bank account had $420, and the bank took X amount of $$$ and now you have $69. Wouldn't you wanna know how much they took, in other words what the X stands for.
What a beautiful response you have here, Nicolette! Your posts never fail to amuse me with your logic and mindset about the concepts embedded into our weekly blog assignments. It was a pleasure reading this post of yours! Superb job!
DeleteX cant be 'x' because the x in the expression represents a variable, and a variable represents an unknown number. If you solve the equation and X is just an x, then the result would be wrong.
ReplyDeleteYou are spot on with your response here, Paulette! I totally agree when you say that if you solve the equation and "x" is just an "x," then the solution (could) be wrong. I enjoyed reading your response!
DeleteThere always has to be a variable in a algebraic expression. And if the variable doesn't represent a number then the statement wouldn't make sense. Or it wouldn't have proper answer to the equation.
ReplyDeleteJanelle, thank you for such a great response. Although you are on the right track, be careful as not all algebraic expression require the presence of a variable. For example, 1 + 1 is considered to be an algebraic expression but it does not contain a variable. Aside from the one point I wanted to clarify, excellent thinking!
DeleteIn an algebraic expression there always has to an variable. the variable always represents a number in the problem, so if there is nothing variable in the problem you cannot answer the problem.
ReplyDeleteThank you for your response, Victoria. As I stated in my response to Janelle's post, remember that when we SOLVE for the value of our variable, we are dealing with EQUATIONS. When we just have expressions, all we're doing is SIMPLIFYING. Please take note of this for the upcoming posttest on this unit of study. Great work!
