should an 8th grader be able to solve this

<p>I tried to get the girl I’ve written about in other posts to solve this, she can’t and doesn’t want to know how, really</p>

<p>Assume you are driving at 60 miles per hour. </p>

<ol>
<li> How far do you get if you drive 1 ½ hours?<br></li>
<li> If you are driving 25% over the speed limit, how fast are you going?<br></li>
<li> If you are driving at the speed from question #2, how long does it take you to go the distance in #1</li>
</ol>

<p>I look forward to your answers. Please give answer for each question #1, #2, #3</p>

<p>What is the speed limit?</p>

<p>oops forgot that line in my haste to copy and paste. Speed limit is 60 mph</p>

<p>Yes, those are simple basic math questions. An 8th grader working at least at grade level in math should be able to answer those questions.</p>

<p>Pretty simple problem and definitely at the 8th grade level.</p>

<ol>
<li>60 x 1.5 = 90 </li>
<li>60 x 1.25 = 75</li>
<li>90 = 75x
90/75 = 1.2 hours</li>
</ol>

<p>Those are absolutely doable by an average 8th grader.</p>

<ol>
<li>90 miles.</li>
<li>75 miles per hour.</li>
<li>1.2 hours</li>
</ol>

<p>Your answers are not correct without the correct units!</p>

<p>20% of 60 minutes = 12 minutes.</p>

<p>correct answer is 1 hour 12 minutes.</p>

<p>^Unless you are in a Mathcounts competition where if you put the wrong units you’ll be marked down, but no units you’ll be marked correctly. :D</p>

<p>I’d say an 8th grader should be able to do these problems.</p>

<p>I think an 8th grader or even younger should be able to solve this.</p>

<p>I agree that an 8th grader should be able to do this, but she can’t.</p>

<p>her school (where she will finish 8th grade) uses the Bloom’s Taxonomy grading.
I’ve looked at this grading scale and think it’s stupid. I’ve been begging this girl’s dad to get her tested at a Huntington Learning Center (or similar). I’m really afraid for her when she starts high school and is expected to take Algebra I.</p>

<p>sue, 1.2 hours, 1 hour and 12 minutes, and 72 minutes are all equivalent and therefore are all correct. I would accept any of the three answers from my students, unless the directions specifically indicated the answer be given in a particular way. </p>

<p>And, yes…now that I think about it…this is more like a 6th grade question.</p>

<p>I would not recommend those learning centers. They are expensive and often the instruction is group instruction not particularly catered to your student. </p>

<p>Can you get a recommendation for a private tutor who is familiar with your state standards, as well as standardized assessments that can help pinpoint areas of weakness and strength? This will likely cost you the same or less per hour than one of the learning center businesses, and will provide 1:1 instruction to the student addressing her areas of need.</p>

<p>Ugghh. My brain has turned to mush since going through menopause. So frustrating. I can’t even do 8th grade math problems now.</p>

<p>

<p>When I was in high school and college all of my science teachers gave ZERO credit for an answer with no units. It sticks in my my mind many years later.</p>

<p>I’m not the parent. I can’t do anything. I can’t make her parents do anything (see other posts about this girl I’ve made recently).</p>

<p>I feel like I am more concerned about her than her parents are!</p>

<p>Sounds like you are trying to be a helicopter parent to someone else’s child.</p>

<p>I was standing at a Bloomie’s sales rack, there was a group of high school girls trying to figure out 40% off the original and 10% off on all items on sale. </p>

<p>D2 is 5 years younger than D1. When she was in grade school, she was taught math by “concept” for a short period of time then go into depth each time they came back to the same concept. What that meant was they would teach multiplication, but only touch on the way to use multiplication and leave memorization for later. They would teach percentage by discussing how it is used then come back to it few months (years) later. What resulted was D2 not able to do basic math even by 5th grade. We had to send her to Kumon for a year. It was the best thing we did for D2. She learned to do 1+1, 1+2…1x1, 1x2…She felt so comfortable with basic math that she was then able to learn more complicated math in class. She said she was so nervous before because she was afraid her teacher was going to call on her and she wouldn’t know how to do 12 X 6.</p>

<p>D2 did end up on the highest math track when she went to high school.</p>

<p>Most 8th grade students cannot solve simple problems involving percentage changes, as I mentioned in another thread:</p>

<p>[California</a> abandons algebra requirement for eighth-graders](<a href=“http://talk.collegeconfidential.com/15435248-post21.html]California”>http://talk.collegeconfidential.com/15435248-post21.html)</p>

<p>For the question</p>

<p>

Only 36.5% of 8th-graders got the correct answer, D.</p>

<p>The answer to OP question #3 is that it’s going to take a lot longer than you originally figured if a cop is writing you a ticket for speeding.</p>
