This is a center activity with 8 task cards that have announcements made on the radio that include numbers. The students have to write the numbers in expanded and word form on the recording sheet. Then they create their own announcements and put all of the numbers in order from least to greatest.
There is also a memory/matching game where students have to match cassettes with word form and standard form. This can be done independently, with a partner, or in a small group.
