## Reflection: Checks for Understanding Simple Interest - Understand Your Money! - Section 3: Summary + Homework

The purpose of this table discussion was really for me to determine if students noticed that the formula I = Prt is really the same as original x percent = new, then you multiply by the number of years you are looking for.  And in fact, kids did recognize that it is the same equation we have been working with :)  I heard a lot of "it's the same thing we've been doing" across the room.  It is really cool to see kids making connections, and in this case realizing that they do not have to learn a whole new equation makes them feel more at ease.
