The classroom happenings of Ms. Simonsen's 4th graders at The International School in Genoa.
Hello! Welcome to the blog for 4th Grade Purple. On this blog you will find links to various math and ELA sites, our kidblogs where student writing can be viewed and commented on, and information about our class. We hope you enjoy having an eye into our world.
Students are learning how to add and subtract fractions with unlike denominators. This can be a tricky tricky process. We've used both fraction strips and numbers & symbols to do these processes. We are only looking at changing one fraction to have a similar denominator as the other, where the larger numbered denominator is a multiple of the smaller numeral (ie 1/2 to 3/6 - sixths, as opposed to 1/2 and 1/3 to a common denominator).
By using two different methods, students: a) develop better conceptual understanding, and b) show how they can prove their answer is correct.
