I Have..Who Has?! This is a fun and challenging game that may be used as an activator for double digit addition or as a quick assessment to evaluate understanding. This game may be played in a whole group math lesson or small groups. Differentiation is an option as the 24 task cards vary in difficulty.
Pass out 1-2 cards per student. Allow your class time to solve their addition problem(s) with individual white boards, math journals, or base ten blocks. Begin the game using the START card and continue until the LAST card is read. I enjoy using this type of activity as a quick assessment to see who needs additional tutoring or as a "ticket out the door" activity. Rotate cards as long as time allows. Enjoy!
