## Reflection: Relevance Introduction to the Spending & Saving Project - Section 3: Spending and Saving Part 1a: Saving Money

Luis anecdote: "This doesn't make sense," he said.  He was trying to do all the work in his head.  He got to a problem that he couldn't think about intuitively in his head.  This was finally a moment where algebraic moves seemed to be a useful tool to him.  Even after he solved the problem, he was having trouble deciding if the solution made sense.  This took us back to the definitions of x and f(x), and he had to slow down again to read that.  I share this story because, in general, this assignment is designed to get kids interpreting, paying attention to detail, and using what they know about math.  This is indeed what happened!
