Expanded notation

After practicing place value, we work with expanded notation and comparing values.

To do this you'll need an egg carton for each student.  I wrote a letter home early in the year asking for them and got plenty!

The egg carton has to be the kind that holds a dozen eggs.  Starting at the top right label each top cup ones, tens, hundreds, etc until you get to hundred thousand.  Place 9 manipulatives in the carton.  Close the lid and shake.  Open up and count how many manipulatives are in each cup.  Write the number.  Compare with a partner.  Who has more?

Really fun and the kids love it!
