Why invert and multiply. Sarah got one symbol wrong here but in the full 15 min video the symbols are right and we understand the concepts and what we are doing when we divide...she uses the manipulatives to SEE what she's doing...if you want to see the whole thing and how we use manipulatives to to make it CLEAR go to Sarah's page here:

Note Sarah wrote the division symbol instead of the multiplication symbol...when she was inverting and multiplying but I added it anyway because it shows the concept yet again of why invert and multiply.
