I see 33 in pink. I want to know how many more to 81.

Then I want to record the relationships as an inverse.  So I am thinking I could fill in the blocks to 81 or I could fill them in in my mind. If I added 50 it would be too much. I would be at 83. So 2 back from 50 is 48. I think 48 + 33 = 81      70 + 11 yes it works

How do we start with inverses.  In this ppt  I get started on what’s missing to show with blocks or with dot collections how to develop inverses.
