I didn't know that!!
When Mrs. Truelove introduced the class to the fraction bars, I rolled my eyes and thought of it as silly. I've never been a good mathematician and when we're talking about fractions, I pretty much tune everything out. Who knew that "fraction bars" were the key to unlocking my understanding of fractions. I have always understood how to use them in different operations but I never understood the concept. For example, 4/5x1/2 is 4/5 of 1/2. You would have to divide the half fraction bar into tenths and shade in 4 of the 10 bars which would equal four tenths (4/10) or two fifths (2/5). Until I used the fraction bars I did not understand why it would equal two fifths besides 4 x 1 =4 and 5 x 2 = 10, reduced to 2/5. Instead of hating fractions, I actually don't mind using them now. I have had success with them every since. I will definately use fraction bars to teach my class about fractions and I will encourage my students to use them in solving operations that involve fractions.
