The Shark swim team uses double digit subtraction with regrouping to help them reach a goal. ( )

a group of sharks come together in order to swim enough laps to go to swim camp. Together, they subtract and keep up with the amount of laps that everyone swims on a daily basis. It's a great informational book that the kids will enjoy.

This is a book about subtraction. It is a great tool to use if you are introducing a new concept or reviewing.

The Ocean City Sharks want to go to state but they do not have enough money. To raise money they have to swim 75 laps. The book helps students with subtraction by subtracting the laps they ahve completed.

I used this book for a 3rd grade read aloud. It is really good to study addition and subtraction for 1st or 2nd grade. We used other aspects of this book to study multiplication and division. We made up our own problems to figure out along the way.
