I’ll be more than happy to help you with the problem.
The first thing you want to do in any problem like this is to draw a picture. This will allow you to label each section. It’s easier to solve the problem if you can see an image of it. You’re going to want to find the total length of the stilt first.
Look if you have a heresy bar broken into 6 pieces and I told you that I eat 4/12 of it, how would you figure out how much was left?
Use the same strategies you would use to solve how many pieces you would have left over of the heresy bar to answer the IMP problem.
Try the problem now. Sometimes we just need a little hint to get us started on the right track.
If you’re able to solve the 1st problem, try the challenge problem.
Hint for the challenge problem.
If I tell you that 50% of 12 is 6, what would be 25% of 12?
Let me know if you need some more Help?
Sincerely,
Angelica

Instructor Comments:
Angelica,
I think your approach to helping her is excellent. I like the idea of focusing on a Hershey bar. However, I am not sure I see the parallel. First, why did you pick 4/12 (instead of 1/4)? Are you implying that when she solves the IMP problem she should use a common denominator? The reason that I ask is that many kids have done that, and it leads them to add 1/4 + 1/3 = 7/12 and then conclude that 5/12 are left. But, this is not the case because the 1/3 does not refer to the whole pole. The rest of the hint is nice however.
The hint for the challenge problem is excellent.

Look if you have a foot long Hershey bar broken into 6 pieces and I told you that I eat 4/12 of it, how would you figure out how much was left? (How much would the 4/12 of a foot be?)Remember to answer in measure unit form. EAMPLE : 1mile, 3 miles, 4 ft....

Answer(or question to Mentor): Angelica, I think that the answer is a.3/4 of a foot b.5 7/12 foot. First what I did was I added 1/4, 1/3, 5, and 3/4 because I wanted to see how long the stilts are. Then I took that answer, which was 6 1/3, and subtracted 3/4 of a foot because it says that the storm surge covered 3/4 of the stilt that was sticking out of the ground so you have to subtract the 6 1/3 and 3/4 and that is how I got my answer, 5 7/12 for letter b. For letter a I just took the information from the last sentence of the problem which was that the storm surge covered 3/4 of the stilt that was sticking out of the ground so I thought the answer was for letter a, 3/4 of a foot. Thank you very much for helping me on this problm but I still do not get the claeenged problem. Once again thank you.

Mentor Reply: Hi Kayla,
I’m sorry but your answer was not correct. I can see you had the right idea but you first needed to get the measure of the whole stilt. They gave you a clue that the dry portion of the stilt in 2000 was 5 feet. I didn’t see you used this clue in your solution. Lets solve the problem together.
Do the problem with me:
Start by drawing a stilt pole and cut it into 4 equal parts.
--You do this because you are told that ¼ of the stilt is stuck in the ground.
--You are left with 3 parts which is above the ground.
You are told that in 2000, 1/3 of the stilt is under water. The measure that’s dry is 2/3 which is 5 feet. ( You are told that 5 feet is dry. )
--Look 1/3 +1/3 = 2/3 Then 2.5 + 2.5 = 5 So 2/3 = 5 and 1/3 = 2.5
--You now know that each part of the stilt that you cut equals 2.5 feet
--This then tells you that the stilt is 10 feet. (2.5 +2.5 + 2.5+ 2.5 =10)
In 2002 the surge covered ¾ of the stilt that was stuck out of the ground.
--7.5 feet is stuck out of the ground (2.5 +2.5 +2.5 = 7.5)
--So you then need to know how much of 7.5 feet is 3/4 .
--7.5(3/4) = 5.63 feet. This is the measure which is submerged in water.
--5.63 feet is answer to (A)
If you know that 5.63 feet is the measure submerged in water and they want to know how many feet was left dry.
--Subtract 5.63 feet from 7.5 feet and you get 1.88 feet which is the measure that’s dry.
--1.88 feet is answer to (B)
Kayla, the clue of 5 feet is how you determine that each part (after cutting into 4 equal parts) is 2.5 feet. After knowing this, you can solve the whole problem.
Answer to challenge problem:
If Bob used stilts the same length as Andy’s stilts which were 10 feet, 40% of 10 feet is 4 feet which is the measure which is stuck in the ground in Bob’s house. This then gives us the measure of 6 feet which is above the ground. (10-4=6) You found that the storm surge o f 2002 was 5.63 feet from the IMP answer A. If Bob had 6 feet of stilt above the ground and the 2002 surge was 5.63 feet, Bob’s house did not get washed way; because 6 feet is larger then 5.63 feet.
I’ll be waiting for your next IMP answer.
Sincerely,
Angelica

Answer(or question to Mentor): Angelica thank you for clearing it up for me but when I subtracted 5.63 and 7.5 it came out 1.87 not one 1.88. I do not know if you typed it on a accident but I was just wondering. Other than that it came really clear. Once again thank you.

Answer(or question to Mentor): Hi Angelica,
I think the answer for number one is 330 calories. The first thing i did was I took 14 grams of fat and multplied it by nine calories because it said that one gram of fat has 9 calories in it and that was 126 calories. Then I took 36 grams carbohydrates and I multiplied that by 4 calories because there is 4 calories in 1 gram of carbohydrates and I got 144 calories. Next I took 15 grams of protien and multiplied that with 4 calories because there are four calories in 1 gram of protien and that was 60 calories. Then I added all thoughs answers together and I got 330 calories in the cheeseburger. For number two I got 2 13/21. First I took 14 grams of fat and multiplied it by nine because there is nine calories in 1 gram of fat then and I came out with 126 calories. Then i divided 126 calories into 330 calories because that is how many calories there is in the whole cheeseburger and I got 2 78/126 calories then i simlified it and i came out with 2 13/26 calories. So the answer is 2 13/26.

Mentor Reply: Hi Kayla,
Your answers were so close but not totally right. The answer to #1 of 330 calories is only part of the information you need to answer the question. You determined the total number of the calories in a cheeseburger. Yet question #1 asks you what fraction or percent of her daily intake has she ingested? You are given that the recommended daily allowance for calories is 2000 cal/day. How would you determine what 330 calories out of 2000 calories is?
HINT
How do you know that 50 of 100 = ½ or 50%?
Remember a fraction = N/D
Denominator (D) is the total number of the whole and
Numerator (N) is the total fraction (part) of the whole
Your answer to #2 shows a great effort in solving the problem. It appears you were trying to simplify but you came out with the wrong answer. You divided the total number of calories by the number of calories in fat in a cheeseburger. Look at the above hint to solve the problem correctly.
Try to answer the problem again and submit a new answer.
Don’t forget to try the challenge problem.

Angelica

Instructor Comments: Angelica,
My response is just about the same as I wrote for your first student. They were answering a question that is no longer there, but that is not their fault! So, congratulate them on figuring out how many calories are in the cheeseburger, and then tell them what the current questions ask. HOWEVER: please note that you don't want to directly tell them the answer. Even saying 'How would you determine what 330 calories out of 2000 calories is?' really does tell them that the answer is 330 over 2000. So, since we have more time this time, try not to tell the answer right away. Also, you might want to suggest that the answer could also be written as a percent. I don't think it is necessary to give the hint about fractions. These students do/should understand fractions, and just because they didn’t answer the fraction part of the question doesn't necessarily indicate that they don't understand basic ideas of fractions. Wait until you see what THEY write and then INCLDUE whatever they write in your response.--DR. Bowers

The regular problem I get but the challenged problem I don't. I mean i think i am on the right track but i do not know. Please tell me if it is right are wrong because if it is wrong then please tell me so. This is what i am thinking you should add all of the fractions which were 1/3 3/4 1/2 then you would come out with 19/12 then change it to a mixed number that would be 1 7/12 then you add the three because that was left over then that would be 4 7/12. I took the fractions and i added them because you are trying to see how many chicken McNuggets you had to start out with. So i think the answer is 4 7/12.
