# Adding Fractions With Unlike Denominators Math With Mr. J ((BETTER))

One reason students struggle with fraction operations is that fractions are just less intuitive than whole numbers. Students constantly add and subtract whole numbers in their everyday lives, even without realizing it. On occasion, they even multiply and divide.

## Adding Fractions with Unlike Denominators | Math with Mr. J

Adding and subtracting fractions with unlike denominators is more complicated. Students need to convert to equivalent fractions, which relies on skills developed by multiplying fractions. So students first learn those concepts before returning to addition and subtraction with unlike denominators.

Sheppard Software offers a couple of cute games for the youngest math students. In this game, called Bugabaloo Addition, children are shown a number of "bug shoes" on the left and the right. The game asks the child to add the two groups of shoes together, and then pick the bug with the correct number printed on it. This game teaches addition through a graphical display that lets the child see and count the shoes. With the numbers right underneath, children easily make the association between the visual cues and the act of addition.

For slightly older kids, there are a number of very popular arcade-style "popup" math games. In these games, the child is presented with a math problem and must find the creature that's holding the correct answer and smack it on the head with the hammer. The comical expression the creature makes and the sound effects make this game so fun that children will forget that they're learning math!

Along with understanding that fractions are built upon whole numbers, students should grasp that they can rewrite the values of fractions into multiple equivalent representations of the same number. In mathematics, any quantity can be represented in many different ways, and this is a critical piece of understanding that students will need to build upon as they move on to middle school, high school, and even into college mathematics.

Some of the things I want to highlight in this section, that I want for us to look at how these concepts connect from whole numbers to fractions, are the concepts of units, and also how fractions are numbers, and equivalent fractions, addition and subtraction with fractions, and the multiplication and division with the fractions.

On this chart, we can see several places highlighted in red or like orange, I think, that are prime places for connecting fractions with whole numbers, including places where the common CORE standards actually explicitly state that work with fractions should be linked to and built on prior understandings with whole numbers.

The fractions having the same value are called equivalent fractions. Their numerator and denominator can be different but, they represent the same part of a whole. We can see the shade portion with respect to the whole shape in the figures from (i) to (viii) In; (i) Shaded

Any two like fractions can be compared by comparing their numerators. The fraction with larger numerator is greater than the fraction with smaller numerator, for example \(\frac713\) > \(\frac213\) because 7 > 2. In comparison of like fractions here are some

Like and unlike fractions are the two groups of fractions: (i) 1/5, 3/5, 2/5, 4/5, 6/5 (ii) 3/4, 5/6, 1/3, 4/7, 9/9 In group (i) the denominator of each fraction is 5, i.e., the denominators of the fractions are equal. The fractions with the same denominators are called

PMA2-GFP expressed in tobacco epidermal cells. Three-dimensional reconstruction from confocal fluorescence image stack of PMA2-GFP expressed in tobacco epidermal cell 120 min after adding 20 μM ABA. Chloroplast fluorescence (in red) is visible from palisade cells immediately below. Compare with Figure 8 of Sutter et al. [S1] in the absence of ABA.

Three-dimensional reconstruction from confocal fluorescence image stack of haKAT1-GFP expressed in tobacco epidermal cell 60 min after adding 20 μM ABA and preincubated with 10 μM FM4-64 for 5 min. Images from the same experiment as shown in Figure 3A. For clarity, images are three-dimensional reconstructions of stacks through the epidermis omitting the outer and inner cell surfaces and parallel to the leaf surface. Chloroplast fluorescence is visible in both GFP (KAT1) and YFP (FM4-64) channels and should be disregarded. Some internal labeling with the styryl dye is apparent without KAT1, but the channel shows virtually complete colocalization where it is visible.

The present work deals with one of the methods of constructing the figured approximants (figured convergents) for two-dimensional continued fractions, which is used for studying the conditions of equivalence of two two-dimensional continued fractions. The formula of difference for neighboring approximants, which is established in this work, is applied to investigate the properties of a sequence of such figured convergents of two-dimensional continued fractions.

A characteristic feature of such approximants is the fact that, for continued fractions, BCF, and TDCF with positive elements, the property of "fork" is valid, i.e., the system of inequalities [f.sub.2k]

First, I was very confused by the point-slope formula in eighthgrade algebra. Now, my father earned his Ph.D. in statisticalmathematics shortly after I was born; mathematics surrounded andpermeated me from an early age, and I merrily waltzed through itselementary school incarnation. But then the point-slope formula hitme. I did not understand how to determine values for slope m andy-intercept b. Indeed, obtaining these values seemed a mysteriousprocess; and, worse, the simple graphs they generated almost mockedme. Exasperated, I guessed answers to all the problems assigned me inthat section of the book and subsequently received my worst everhomework scores in a subject I had always mastered (even without myfather's assistance). By the time I resolved my confusions about theworkings of the point-slope formula, the damage had been inflicted:my academic standing was vitiated, and my adolescent pride, wounded.Although it would be only the first of many other cognitive andaffective struggles in mathematics, this incident perhaps constitutedmy first self-aware experience that mathematics and education,whether taken individually or together, were "not trivial."

The second thing that struck me at this age was the populardistribution of mathematics books. In comparing my father's libraryto those of others, I recognized in his shelves a typical diversityof books, with the disciplines of English literature, music, history,political science, psychology, even economics all represented.However, his readings also included significantly more naturalsciences and, especially, mathematics literature of all nature, fromreference to recreational. It seemed to me that, simply because he"read math," my father read more diversely than did others. Indeed, Isoon concluded, extremely few people outside of mathematics seemed toeven know its seminal works; yet people toiled through "the classics"of other disciplines with comparatively little hesitation. Wishing toremain as broadly literate and fluent as possible, I resolved toinclude mathematics in my future pursuits.

As I continued in the mathematics major, I gradually assumedpositions assisting others with their mathematics. As a grader,Writing Associate, and tutor even as a friend on the dormitory hallor in the house I did not just work, on my own, at mathematics; Ialso communicated, to a diversity of others, its many faces. Andamong those whom I assisted, I found a relatively poor interest in,and a disquieting lack of appreciation for, mathematics. The greatmajority of them did not even exhibit much articulateness in theirmathematical pursuits; they mainly seemed intent on "getting" some"answer" that ever lay beyond them. Indeed, their struggles and fearsbore an uncanny resemblance to my middle school show-down with thepoint-slope formula. Through this mathematics study and practice, Irealized that, even if I not understand the point-slope formula thefirst time I encountered it in middle school or the homomorphismtheorems the umpteenth time that I stared at them in College I couldshare some qualities and applications of mathematics, and supportothers' mathematics achievements, interests, and appreciation. 041b061a72
