Product Description
This 8-page lesson packet is a great way to introduce three-digit subtraction with regrouping by having students first break the numbers into expanded form (hundreds, tens, and ones).

This packet includes:
⇒Instructional Guide
⇒Partner Practice
⇒3-Page Independent Practice
⇒Challenge Page for Early Finishers
⇒Exit Quiz

This packet is designed for 2nd - 3rd grade as it aligns perfectly with CCSS 2.NBT.B.7 and 3.NBT.A.2, but could be used as a review if your students are struggling with subtraction with regrouping. By breaking numbers into expanded form before subtracting, students grow a much deeper understanding of what is happening with the algorithm of regrouping than they do with the typical "borrowing" method.

The answer key for this packet is very detailed. It shows a step-by-step guide for using this method of subtraction for teachers who aren't familiar with it. A thorough instructional guide is also provided which breaks down common misconceptions and provides helpful tips for this lesson.

This packet exposes students to all four types of three-digit subtraction problems:
⇒No regrouping required
⇒Regrouping tens to ones place
⇒Regrouping hundreds to tens place
⇒Regrouping twice- tens to ones and hundreds to tens

A challenge level is also included for early finishers which includes regrouping with zeros. Zeros are intentionally left off the rest of the packet to see if students can apply their knowledge to a new context.
