Adding and substracting Integers

(Unfortunately, I accidentally deleted all but one of my photos. I recreated the photos using some felts I had.)

A) 5+11

B) (-5) + (-11)

C) (-5)-(-11)

D)5-11

E)5-(-11)

F) (-5)-11

G) (-5)+11

The statements that are equivalent are A&E because they both equal 16, B&F because they both equal -16, and C&G because they both equal 6. I learned that it can be easier to add and subtract integers using markers. Students should know different strategies for doing math with integers, so they can find a strategy that is easy for them.
