These sheets allow you to write in the exact multiplication problems you want your students to complete. We have nine weeks in a grading period at my school, so I would copy 9 sheets at a time of the 2 digit x 2 digit multiplication problems and staple them together essentially making a "multiplication packet" for each of my students. I counted each problem as 1 point (99 problems total) and took a grade on the packet at the end of the nine weeks! I did the same thing the following nine weeks for 3 digit x 3 digit multiplication problems.
This helped us master the 5th grade fluency standard 5.NBT.B.5: Fluently multiply multi-digit whole numbers using the standard algorithm.
