Hey Peeps. Today in class we reviewed strategies for adding fractions. The strategies were: Double # Line, Money, and Clocks.

[see one, do one, teach one ]

** Then Mr. Harbeck says *oink oink oink

1) Using the Double # Line:

This stratgie works best when you have ugly fractions to add, and the denominators will give you an ugly common denominator on the number line.

For using the double # Line as you can see in Nintendo's example 9/ 18 and 2/16 were simplified into 1/2 and 1/8. From there we were able to multiply the 2 denominators to get common denominator.

The other way to do this would be t

o work with the ugly fractions by multiplying the 2 numbers denominators and simplifying

your answer.

2) Using Money:

The best way to use money would be when the denominator works with 100. Yes it can be an ugly denominator too!

As you can see in the picture. 1/4 and 1/2 are simple fractions. So 1 quarter of 100 is 25 cents and 1/2 of 100 is a dollar.

When you get 3/50 the fraction is saying 3 50ths out of 100. with is 3 X 2 = 6/100. and you do the exact same with the other fraction. 15/100= 21 cent/100

3) Using Clocks:

Again with clocks the best way to use this would be when the denominator is friends with 60 (60 mins. on a clock) So the denominators that are friendly with 60 are:

/2, /3, /4, /5, /6, /10, /12, /15, /20, /30.

As you can see in the picture. 1/2 and 3/20 simplified out = 30/60 and 9/60. From there since they are already simplified all you have to do is add the numerators= 13/20 (already simplified. The ugly part of the question was 3/20, which mean't 3 2oths out of 60.

that was class!

I like how you used a photo to explain your ideas in the scribe. Clever way to do it. Thanks for scribing.

good job. i like the pics because theyre easy to understand. but if you ever call me a 'peep' again ill slap you

good job i like how u did all ur work with pictures instend of paint because it is easier to understand that way

hey it was a very good scribe i think anyone who was away should get cought up with this scribe

Nintendo D.S

Awesome on the doing the pics and all the math. Very very very interesting Scribe. I easily understanded it.

I like how you gave an example of an hard way of doing the strategies good job :)

Like everyone else, awesome job on explaining and great pics. the thing i would kind of ask would be for anything like homework if i was away.

great scribe. i like how you used pics instead of just explaining.

I like how you showed your work with pictures and used a simple strategy to explain your answers.
