I made this workbook for that "extra time" after we finish our daily lesson. It includes 100 questions of the "missing pieces" that I have seen from students in past years. Including long division, operations with fractions, basic word problems, etc. My goal is to have students work on it independently and learn as they go. It would be a great resource for mini lessons or some extra practice. I added it as a Word Document, so you can change whatever you would like!
