Snowglobes and Long Division



So what do a snow globes have to teach us about math?


Well, Taylor M. just happened to bring in some of her snow globes for us to admire. I was looking around for a memorable subject to use to explain the mysteries of long division. So we imagined that Taylor has a total collection of 324 snow globes and she wants to know how many shelves she needs to display them nine to a shelf.



Once we had the snow globe computation model understood, we practiced with other numbers. We kept thinking that we were dividing snow globes in groups for display on shelves.

Using the partial quotient method, Delaney C. shown above, and other classmates took turns projecting their computations on the big screen for us to analyze.
