“...by recognizing that you need 114 to get to 10,000.”
How is that ‘recognized’? Only by doing a subtraction problem, right? Along with the other subtraction you throw into that solution.
Not buying it. Are you a teacher? Public school?
Not a teacher at all. My career has been corporate finance and computers.
I did score however in the top 1% of the nation in math on both the ACT and SAT tests. And in the top 3% on math of people taking the GMAT which is for Management Graduate Schools.
Its recognized by having a basic understanding of the relationships between numbers, decimal places and sets, etc. The problem is not what CC is trying to teach, but the teaching approach. There is no magic bullet shortcut. Learn the basics and this stuff is simple. Unfortunately, CC skips the basics and over-complicates the rest.
