3 Versions- Missing Addend, Missing Subtrahend, and mixed Missing Addend and Subtrahend
Can be used many ways- I use this as a Math By Myself activity during my Guided Math time. I hide the cards around the room and have the students walk around with the recording sheet and a clipboard. I then have the answers posted so that they can check their answers when they are done. Could also be used as a center or as Scoot.
