## Dueling Discounts

The first problem we did together was called "Dueling Discounts" by Dan Meyer. We studied the problem on the attached page. Students learned how to deal with percentages and decimal numbers.

## Nana's Lemonade

The next problem we studied was "Nana's Lemonade", also by Dan Meyer. Here, students were studying how ratios, equivalent ratios and proportions work in real life situations.
