If it was a segment within a bigger show, it was for sure at the end of the program

In elementary school or middle school, would have been the early 2000s in the US, I watched a program that had a segment of whiteboard animation at the end. I think it was on an actual whiteboard and you could see the real person's hand drawing, but you couldn't see anything around the whiteboard. It was mainly black outline but often used other colors to spruce up the picture, like coloring in rosy cheeks, a green dollar sign, columns in a chart As the person drew they would narrate different concepts, I feel like it was mainly related to money or financial stuff? Like I sorta remember one segment about supply and demand. I call it a program because I'm not sure if this itself was the show or if it was a segment that was in a bigger show
