### Using Local Statistics to Make Fraction Study Meaningful

 Massachusetts' DESE stats are a good resource for infographic creation.
The students have looked at and worked with many fraction models. Now I want to bring greater meaning to the study as we review the concepts they've studied so far. To do that I'll use local stats and if we have time we may be able to make an infographic.

The review will begin with a quick review of "clock fractions" as this leads to a great tool for making accurate circle graphs.

Simplify
Next we'll review what it means to simplify a fraction. We'll use a fraction with a large numerator and denominator such as the number of children in our school vs. children in the entire school district. We'll talk about the ways we can simplify that fraction. Once simplified we'll discuss whether it's better to rely on the simplified fraction, actual fraction, or a benchmark fraction when we discuss this statistic.

Mixed Numbers
After that we'll review what a mixed number is. I'll find a relevant mixed number statistic and we'll discuss how we can change that mixed number into an "improper" fraction or a fraction greater than one.
