This packet has everything you need to introduce regrouping subtraction.
I have included:
4 colored posters
The regrouping poem
4 worksheets of word problems
Example posters with both subtraction by addition and by regrouping
Sorting activity (sort into regroup, or regular subtraction)
I included some blank skeletons for regrouping for those kids who need an outline. I laminated mine and gave them to the kids who struggled more.
