Addition and Subtraction cards that can be used to test for understanding. These printable cards feature 5 addition and 5 subtraction questions for numbers up to 60. It is used as a fun activity where students quiz each other in pair or groups. It is also a great Cooperative Learning activity. I personally used this for my lesson observation and the students thoroughly enjoyed themselves!
