Sudoku and Snowballs in September

The fourth graders are getting pretty good at solving the easy Sudoku puzzles that I give them every week. Today they also worked on the medium 6X6 Sudoku with partners. We talked about how doing puzzles gives our brains exercise.

These Sudoku puzzles came from www.dailysudoku.com. 
We've really been working this week on rounding numbers and dollars. Today we did a fun activity called "Snowball Rounding".
