This is a great video to show to the class to start (or review) regrouping with addition and subtraction…from Math Antics.
This is a really good video on subtracting across zeroes…done in rhyme.
Since subtracting across zeroes is such a bear…here's another video with a different strategy.
This is a terrific site to practice subtraction with regrouping. If you haven't found "Study Jams" yet, be sure to look around the site. It's really, really good!
Love this regrouping rap !
This is the free version…and it's terrific for both addition and subtraction with regrouping!
This one is great for second graders and third graders that are still confused. Very good!
This one is great for review...love the math ninja idea!
