This is a complete common core unit on division for 4th grade students. The unit scaffolds back to include 3rd grade standards for numbers and operations in base ten. Links for resources are included. This unit features three ways to teach division. The first method gives students a deeper understanding of place value and long division. The second method allows students to track the steps of division. The final step is the standard algorithm. Tips and techniques are modeled throughout this unit. The attached PowerPoint can be used as a living document/lesson plan. Teachers are encouraged to add their own slides and "finds" to the presentation.
