Welcome to my math blog! The purpose of this blog is to help you stay informed about our learning and experiences that have taken place during our math class. I have also included links your child (and you) may want to use in order to supplement math learning in 5th grade.

### Comparing Fraction Coordinate Graphing

To begin our math class today, I actually began with a critical writing assignment.  We have been working with changing mixed numbers to improper fractions and improper fractions to mixed numbers and I wanted a little feedback about their thinking.  I asked them to use their notes on page 19 of their journal to assist them in their writing and I posted the prompt:

Which do you prefer, changing improper fractions to mixed numbers or mixed numbers into improper fractions?  Justify your reasoning.

Next, I felt like we needed a little review of two concepts:  comparing two fractions and coordinate graphing.  So I found a worksheet that allows us to practice both.  It is from a book called, "Great Graph Art:  Decimals and Fractions" by Cindi Mitchell.

The worksheet requires the students to create ordered pairs to be graphed.  The x-coordinate is given, but the y-coordinate must be determined by finding the larger fraction and using its numerator.  I allowed the students to practice comparing two fractions using cross multiplication and I also allowed them to use a calculator (this made them very happy!).

We will use these coordinates tomorrow to create a coordinate graphing picture.
