I want to tell you thank you for blogging this. I am an intelligent mom but i was totally over thinking on the problem solving for 12.6. i googked the page number and found this link. You are a total lifesaver for this mom. This is 1/16/2019 6 yrs after you made this video. My son is in 1st grade in North west Florida at West Pensacola elem.
