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.
