This excel spreadsheet was created by Tiffany Nicely for use with her advanced fourth grade math students. Students gain practice in creating the standard form, the word form, and the expanded form of a variety of eight and nine-digit numbers. This numeration skill is easily mastered because the student is able to see two of the forms and must fill in the blank for the third form. The missing blank varies on each problem so practice is achieved in all forms. This can be easily modified for smaller or larger numbers. It contains 10 problems.
