Instructions
Each student has been assigned a topic from "Skills You'll Need" on page 116 to 119 in Unit #4. Your task is to review your section and answer the following questions on the construction paper provided. You will then present your work to the class tomorrow.
Questions
1) Explain how you would solve a problem using this skill.
2) Develop a simple question involving this skill.
3) What is the "golden nugget" (key learning) for this skills?
Once you are done, your final mission is to answer this problem in your notebook. We will review this question after the presentations tomorrow.
A seventh grade class took a poll to find out their favorite ice cream. 1/4 chose chocolate, 1/4 chose vanilla and 1/2 chose strawberry. 2 kids are lactose intolerant and can't eat ice cream. If there are 22 kids in the class, how many kids liked each flavor? Explain
Once you are finished you can practice using fractions on some of the fractions games available here

If there is 22 students in the class, you would think that you would have to divide 22 by four. But you will soon relize that 22 is not divisible by four. And then you will remember that 2 children are lactose intolerant, and that you have to subtract those 2 children from the class, which equals 20. Then you divide 20 by four because 1/4 of the class liked chocolate 20 divided by four = 5. 5 children liked chocolate.
ReplyDeleteOne quarter of the class also liked vanilla, therefore, 5 children liked vanilla.
we all know what half of 20 is, so, 10 children liked strawberry ice cream.
Another way that you could figure this out is by starting with strawberry. Once again we all know what half of 20 is-10. And we also know that 1/4 is half of 1/2. So we could take half of 20 (10) and divide it in half (1/4 of 20) half of 10 is 5,
Chocolate-5
Vanilla-5
Strawberry-10
Lactose intolerant-2
5+5+10+2= 22 children in the class.
Great response! You are correct! I like the way you used specific examples to justify your answer and you provided multiple solutions! Great job!!!
ReplyDeleteLike this awesome paradox. There is a dying grandfather and in turn decides to give his three children a share of his cows.there are 21 cows. There are 3 children.Thje first is to have 1/2 of the cows. the second is to have 1/4. and the last is to have 1/8. But when they do the math{which always ends up having each of the children having to decide to split up one of the cows.} Since none of the children really want split up a cow they sit and wonder.... Along comes an old friend. He has some disgusting mule with him. He said your grandfather would want me to add this to the herd. But none of the children really wanted that disgusting mule. When the friend said just try again they did. The children now realized that they now have an even number. The first took his share of 1 half which is now twelve. Now we have 11 left. Now the next son took 1/4 of the original number leaving just 5 left left. Now the last son took 5 cows which is 1/8 of the original number. Leaving the disgusting mule. The children now happy with their inheritance now walk off leaving this phase of their lives and leaving the old friend chuckling at this odd paradox
