I just thought I would post somethings the video doesnt mention. My kid picked up on them and tried to fry my brain. LOL It is common sense but for
the sake of those of us trying to teach difficult children or even just kids that lose interest easily here are some gimmicks you can use to make them
If you use a number with a zero like 20 or 100 just draw the lines you can and since zero doesnt get a line drawn for it, count the zeros and add
those to the answer at the end.
Also in the video the guy makes circles and vertical loops for each section. You will probably be making diagonal loops in reality.
Ok if you use 3 or more digit numbers: Basically just make squares, and for each new digit add another section of square using the last line of the of
the last square. Then flip the squares to make a diamond. Thats more for organizational issues and sanity.
Then tell them to make diamonds and look for triangles to determine the sections. If you are sloppy like me you lose track. The first and last section
will only form triangles along either the top or bottom lines where they intersect on the crossed lines at the beginning or the end. Like left and
right will be lonely sections. The middle sections like a diamond have top and bottom sets of triangles.
If you realize, it will always be the case that if your largest number has 3 digits you will have 4 sections of squares... 4 digits you will have 5
sections of squares...5 digits you will have 6 sections and so on. The video makes it look easy and it is, but teaching it to a smart ass will bring
up these issues LOL Make them keep that in mind if they are too spacey to not start drawing a spider web or something in the process of teaching
SO make squares as shown and tell them to turn the paper to see the diamond. Diamonds have left and right single triangles and in the middle you have
up and down triangles.
If you skew it some and arent neat just tell them to go up and down from groups of triangles to determine the sections going from left to right and
from bottom line to top line.
The first section starts where the lines intersect on the bottom line and form a triangle. Then the next section will have an up and down set of
triangles but will START on the top line and end on the bottom line. Then the next section will start on the top line and end on the bottom line until
you get to the lonely section with just a top line triangle,...(remember you started with a lonely bottom line triangle for the first section.)
Its convoluted for something so easy, but if your kid is like mine you will understand. And remember to add those zeros!
