The California Mathematics Standards. The California Standards come in two flavors. General Standards Green dot standards. In California the green dot standards are the focus of most instruction since these topics comprise 85\% of the state exams in grades 2 – 7.
In fact, standards designed in this way cut the need for intervention and support maximal achievement for all students
And their data comprises literally billions of people
and problems in student texts
Aconcagua is 6962 meters high. Mount McKinley is 6194 meters high. Which will take longer to climb?
This was the only problem a very bright third grader “missed” in the best elementary school in his district.
A lone goose was flying in the opposite direction from a gaggle of geese.
He cried: “Hello, 100 geese!”
The leader of the flock answered: “We aren’t 100! If you take twice our
number and add half our number, and half of half of our number, and
finally add you, the result is 100, but … well, you figure it out.”
How many geese in the gaggle?
99/(11/4) = 36
And top flight, carefully designed standards are the basic step in achieving this outcome
