These task cards accompany the book, Shark Swimathon, by Stuart J. Murphy. They are a great way to help your students review two-digit subtraction with and without regrouping. And using QR readers to check answers makes the activity more engaging for students.
This product comes with 24 task cards and a page for recording answers. 14 cards feature math equations, and 10 cards feature word problems. They can be used in math centers, group activities, or in a SCOOT game.
We hope you enjoy them! :)
