Help students see patterns in numbers through regular exploration. Use these ready made activity sheets to make your own 1-100 Chart math station.
The work slowly and gradually gets harder with more blanks as you go through the document, but with one activity a week, the students should have plenty of time to master each level of difficulty.
Since I use a 1-100 pocket chart, the "Missing Numbers" section is used to identify numbers I have removed from the chart that week. If you want to use individual 100 charts you could laminate and change out stickers over various numbers each week.
I have included enough pages for an entire school year of centers if used weekly (plus a few extras), but you could use them in any frequency you wish.
