Happy 100th Day!

Today we celebrated 100 days of learning in fourth grade.  During Math Centers, all of our multi-digit multiplication and division problems included multiples of 100.  We've been using expanded multiplication and division algorithms: 

During our Core Lesson, we made decimal designs on hundredths grids, then used fractions and decimals to describe the color for part of the design.

My favorite activity to celebrate our 100th Day was the 100 meter dash.  We collected data about how fast we can run 100 m, then used our knowledge of place value to compare our data to our classmates' data.

Fourth Graders--how many days have you really been in school?  Consider you've been in school since kindergarten, and there are 180 days each school year.  Submit evidence of your solution tomorrow for Chief Cash.  :-)
