Obama: STEMEducation a must-have
Science, technology, engineering, and math (STEM) education is of the utmost importance to all students and is critical to U.S. competitiveness, said President Obama at an April 20 town hall event held on Facebook’s Palo Alto, Calif. campus

Realize that the container shape doesn’t change the subQuan
but does change the quantity: base number
representation.
SubQuan different containers

Hands-on SubQuanning
SubQuan with your hands to engage your kinesthetic memory.
![Page 9: Oi ed 2011 dr iot1 update](https://reader033.fdocuments.us/reader033/viewer/2022042816/5596a5e81a28ab2b5b8b4785/html5/thumbnails/9.jpg)
“I see it!”
Cement your kinesthetic memory to your visual
instinct with an Aha moment.

Seeing Reality
If you did the exercises at
www.itonlytakes1.org subQuanning these
cubes should be quick.
(Answer on next page.)

Subquan Numbers Have Shape
We recognize squares and cubes but what are the others? Hmmm.
(Answer from previous page is two-six-five!)
others ?
square
cube
?

The Right Hand
Specialized 3-D binary base
number device used for naming
shapes and ‘really‘ learning how to count on your
fingers. (Answer: 84)

Virtual Cubes Are Beneficial

Snap-to Makes SubQuanning Quick
Not only can the little cubes snap in place but entire
groups can be easily moved.
(Can you figure out how many cubes are there now?)
![Page 15: Oi ed 2011 dr iot1 update](https://reader033.fdocuments.us/reader033/viewer/2022042816/5596a5e81a28ab2b5b8b4785/html5/thumbnails/15.jpg)
Meta-patternsSame SubQuan,
Different quantities!
What is the meta-pattern? (see next slide)
![Page 16: Oi ed 2011 dr iot1 update](https://reader033.fdocuments.us/reader033/viewer/2022042816/5596a5e81a28ab2b5b8b4785/html5/thumbnails/16.jpg)
The meta-pattern is five-six.
Where is the five in this data?
Where is the six?

Lynn Arthur Steen warns, "an innumerate citizen today
is as vulnerable as the illiterate peasant of Gutenberg's time."
