a)5+11=16

b)-5+(-11)=-16

c)-5-(-11)=6

d)5-11=-6

e)5-(-11)=16

f)-5-11=-16

g)-5+11=6

 

Questions:

Explain which statements are equivalent and why.

Question A and E are equivalent because they are the same question 5+11=16 and in E all you do is make the subtraction signs plus signs. Question B and F are equivalent because again they are asking the same thing which is -5-11=-16. Question C and G are equivalent which is -5+11=6, this question is the same thing as A and E where the subtraction signs become plus signs so the question becomes the same which makes the answer the same.

What did you learn by completing this activity?

I learned that counters could help you count and figure out problems easier sometimes. I also learned that equations and questions could look different but be the same.
