Interactive Math Journals: Number Forms

Number Forms:  Nebraska standards stress standard, expanded, and word (written) form for numbers.  To help students differentiate these forms, we used sticky notes to write each form out.

To help understand expanded form, we cut 3 sticky notes into 1" vertical strips [make sure there's sticky on the ends].  Stick them down with the sticky on the right.  Write the value of each number on each strip, lining them up so the digit shows, but the zeros are hidden.
