What is the best way to teach fractions to first graders using the Montessori approach?
Q. I'm having a difficult time to plan a lesson using the Montessori method. It's my first time to teach montessori and I only have a little background about it. I'm assigned to teach fractions in Grade 1. What is the most effective way of teaching fractions to first Graders using the Montessori approach?

A. You aren't a trained Montessorian and yet they have you teaching lessons? There is something wrong there. To begin with there are montessori lesson plans for teaching fractions, just like there are Montessori lesson plans for teaching everything. That's why you should be trained before you actual teach, or at least be working closely with a trained teacher. Is there anyone at the school who will share their manual with you and at least be your mentor while you take your training. You are taking your training aren't you? A quick over view is that you start with a unit bead and talk to the children about what it is and how it they have been using them to make numbers for quite a while now. But now you guys are going to do something… [cont.]

How I can calculate dry air mole fractions of a particular gas?
Q. The mole fractions of a particular gas in the ambient air is known to me. How could I Convert them to dry air mole fractions? I have Humidity in th air values.

A. For get gram of humidity we to know Humidity in the air value.for example 20% of particular gas in the ambient air is humidity so in 100g of this air is 20g humidity. then we have to minus humidity from the ambient air. then we have it.

What is the most easiest way to convert fractions into percentages on paper?
Q. I have a fractions quiz tomorrow and I have a difficult time finding them!
Asked by Victor P - Thu Feb 5 20:20:22 2009 - - 2 Answers - 0 Comments
A. The simplest method is to use a calculator: Steps: Divide the top of the fraction by the bottom, Then multiply the result by 100 and read off the answer ! Example: What is 5/8 as a percent? Get your calculator and type in "5 / 8 =", the calculator should show 0.625, then multiply by 100 and your answer is: 62.5% (remember to put the "%" so people know it is "per 100") Of course you can do the division in your head or on paper if you don't have a calculator! Another Method Because percent means "per 100", you can try to convert the fraction to ?/100 form. Follow these steps: Step 1: Find a number you can multiply by the bottom of the fraction to get 100. Step 2: Multiply both top and bottom of the fraction by that number. Step… [cont.]

Once you have typed in the sum and pressed equals you then press the button that looks vaguely like this: S>>D. This will then convert it to whatever it didn't give you. So if it gave you the answer as a fraction it would turn it to a decimal and vice versa. The button is inbetween the right closed bracket ) and a button: M+. Or just above the delete (del) button.

Is it worth the effort to devalue fractions in arithmetic or math classes?
Q. According to one article featured at Yahoo, one professor believes that fractions and long division are not necessary to teach young students, when they have calculators and computers to do the math for them. What if students will never understand how math works withoug learning the basics such as fractions? Aren't they important in everyday tasks such as cooking? What if all the digital technology disappears?

A. It's easy. You just need to find a common denominator and then do the operations regularly. I'll walk you through a sample question. (-3/7)-(4/5) Now, we need to find the least common multiple of the two denominators, 7 and 5, before we begin subtracting. 7 and 5 are both prime numbers, so their least common multiple is 35. Let's now multiply the denominators so they both become 35. Remember, anything done to a denominator has to be done to a numerator, so we'll multiply the denominator by the number we need to obtain the Least common multiple of 35, and multiply the numerator by that same number. -3/7 * 5/5= -15/35 4/5 * 7/7=28/35 Now, let's rewrite the original problem with our new fractions with common denominators.

A. It's easy. You just need to find a common denominator and then do the operations regularly. I'll walk you through a sample question. (-3/7)-(4/5) Now, we need to find the least common multiple of the two denominators, 7 and 5, before we begin subtracting. 7 and 5 are both prime numbers, so their least common multiple is 35. Let's now multiply the denominators so they both become 35. Remember, anything done to a denominator has to be done to a numerator, so we'll multiply the denominator by the number we need to obtain the Least common multiple of 35, and multiply the numerator by that same number. -3/7 * 5/5= -15/35 4/5 * 7/7=28/35 Now, let's rewrite the original problem with our new fractions with common denominators. Now that we… [cont.]

Can you help me explain to my son the need to learn fractions?
Q. He complains that he doesn't need to learn fractions because he's never going to use them in the "real world." I told him fractions are used every day in the real world and he wanted some examples. I said you use fractions when you're cooking, he said he's never going to cook and if he does he'll use a measuring cup. So I told him that if he ever wants to do woodworking or metalwork he'll have to use fractions. He said, yeah, that's my dream job. I said you work with fractions when you talk about your gas tank (I have a quarter tank of gas) he says he only needs to know quarter, half, three quarters and full. I said you work with fractions when you work with money. He says I'll never have to know what 3/8 of a dollar is. What the heck? How… [cont.]

A. If all else fails you have to have two years of college for the lowest degree that you can get...Math is included in that. What happened after he learned how to add~then came subraction multiplication~then came division fractions~algebra is pretty close Algebra is needed to make it through college. Believe me I didn't take Algebra in school and you aren't cool when you get to College and don't know any algebra... I didn't finish HS but went to college. My point to get my GED I had to know fractions...he will have to learn fractions to graduate from school. Want some help on how to make if fun now? Measuring can be done with fractions very fun. Get a tote or box or sandbox measure out different amounts in measuring cups. Make a game… [cont.]

How do you add and simplify algebraic fractions?
Q. My mind has gone completely blank so could someone please explain how to add and subtract algebraic fractions? These are two of the questions to help you base any examples you use on (brackets indicate the place of the line which separates the numerator from the denominator): 5/2x - 8 and 2x + 1/x+1 Thank you.

A. ( 5 / 2x ) - 8 = (5 / 2x) - (8 / 1) The common denominator of 2x and 1 is 2x. Make that the denominator of the answer. 5 is already over 2x, and does not need changing. 8 needs to be multiplied by 2x, as it is being divided by a 2x which was not there before. That gives: 5 / 2x - 16x / 2x = (5 - 16x) / 2x. 2x + (1/x) + 1 Common denominator has to be x. 2x becomes 2x^2 / x, and 1 becomes x / x. The sum is: ( 2x^2 + 1 + x ) / x.

How do you turn theses decimals into fractions?
Q. Im doing my summer algebra homework and I am having a lot of trouble on turning these decimals into fractions. .1212... .4555... .8222... .4545... .8585... I know that's a lot of problems but the thing I am having trouble is the repeating decimals are not the same number. Thanks for trying to help though.

A. If they only go out 4 decimal places they are ten-thousandths... or xxx/1000.
