Multiple Choice

What do we have to do to tiles when we move them from the left side of our equation to the right side?

• flip them over

• divide by 2

• add 1 tile to both sides

• take them off the mat

Multiple Choice

What do we have to do to if we have a negative x remaining on the left side of our mat?

• flip ALL tiles over

• divide by 2

• add 1 tile to both sides

• flip over half the tiles
