First and Second Grade Common Core Standards include mentally adding 10 to a given number. "I Have, Who Has" is an easy to use game that is great for practicing addition with 10 more. "Robot Addition" covers adding 10 to two digit numbers. It includes 28 addition fact cards.
Directions for use, Common Core standards, and bonus activity sheet are included.
