This document is an excellent tool for teaching students 2-digit by 2-digit Division. It includes 100 pages of exercises and corresponding corrections, with 21 operations per page per day. The worksheets are accompanied by the solutions, for a total of 4200 Division exercises and their solutions. This resource has been very effective in helping my students learn the steps of compound number Division and has given them the motivation and confidence to succeed. I highly recommend this resource.
