This set of task cards gives students practice with determining the missing addend for addition fact families through 20.
There are 24 cards in the set. I have provided one set that students can solve and use the included answer key to check their work.
I have also included a 2nd set with the same problems with a QR code for students to use to check their work.
I suggest laminating the cards and letting the students write their answers with a dry erase marker. However, I have also included an answer sheet students can use to record their answers if you would like to have them do so.
