Integer Investigation.
This is a chance for you get some feedback from your classmates. Remember….the assignment is to
create four unique equations for your integer. Each equation must at least one of the following:
brackets, exponents, division, multiplication, adding and subtracting.
Each equation should equal your unique integer. Look at the rubric on your assignment sheet (and on
the back) to ensure you reach the highest level possible.
Below, write your four expressions with “answer keys”. Next class, you are going to switch equations
with you peers so you can get some feedback on your equations.
