During the event, Shad Moarif, the founder of Karismath, will lead brainstorming about mathematical videos and dynamic mathematics in general.

The recording will be at http://mathfuture.wikispaces.com/Karismath

Event challenge! Reply to this email with your thoughts!

What types of the Grid do you see from the pedagogical perspective?

In a grid, there is an obvious connection between the product cell and the simultaneity of two bits of information coexisting within it. Shad is exploring ways of breaking this connection down into a sequence of transitional steps by distilling them visually. Shad has categorized the Grid into eleven types according to their uses for storing, sorting, and displaying numerical information (see below).

What pedagogical types of the Grid come to your mind?

  • Saturday, January 14th 2012 we will meet online at 11 am Pacific, 2 pm Eastern time. WorldClock for your time zone.
  • Run the Java applet and follow instructions.
  • If this is your first time, come a few minutes earlier to check out the technology. The room opens half an hour before the event.

The GRID as Pedagogical Tool


Shad explains in more detail:

The grid, composed as it is of horizontal and vertical “bands”, produce trapped spaces of specific sizes:
These spaces represent the congruency of a pair of simultaneously existing elements (a) and (b).
There is an obvious connection between the product cell (ab) and the simultaneity of two bits of information coexisting within it. The connections take multiple forms. The grid, therefore, is generically designed as a tool for creating mathematical content (the Math itself) as well as explaining it (pedagogy).
I am exploring ways of categorizing types of Grids from "an ordered pair" perspective i.e. (x) ascending levels of cognitive development (Elementary to High School), and (y) rising levels of mathematical complexity:

1. Grid for Analysing Visuo-Spatial Correspondence
2. Grid for Pairing People with Corresponding Activities
3. Grid for Pairing Abstract Values and their Quantity
4. Grid for Product Relationships
5. Grid for Displaying Identical and Similar
6. Grid for Intepreting Data
7. Grid for Representing Ordered Pairs
8. Grid for Displaying Transformations
9. Grid for Measuring Slopes
10. Grid for Measuring Length of Straight Lines
11. Grid for Visualising Functions

The idea is achieve as much accuracy as possible in pairing x and y. All the courseware that envelopes and integrates the use of the grid has to be created and explained simultaneously via animation, and accurate pairing is integral to designing the courseware.

This webinar is to invite ideas, insights and suggestions regarding my Grid Categorization, more specifically around the labels I have used. 

About Karismath

Karismath mediates visually between Math and the learner. It makes math concepts visible, accessible and useable. Learners delve deeper behind the numerical surface of mainstream Math to explore visual constructs of concepts. The use of visual scaffolding traces this natural path of learning. Initially using imagery but no numbers, the program gently moves learners to abstract concepts and mathematical operations. Designed for all whom the curriculum has failed.

Karismath YouTube channel offers free lessons http://www.youtube.com/user/Karismath such as this one on early algebraic thinking  http://www.youtube.com/watch?v=zKqEMcys8Uk

Maria,

this is in response to your early morning inquiry, viz., " Do you have content related to grids or tables?"

Tables:

1. Modulo arithmetic

2. MinMax theorem

3. Calendar magic

4. Arithmetic magic matrix

5. Gergonne magic trick

6. Magic in Square

7. Filling an array with 0s and 1s and counting

Grids

1. Affirmative action

2. Pick's Theorem, Geoboard

3. Ballot Lemma

4. Fill hexagonal grid

5. Framer and Wife to catch Rooster and Hen

6. Getting a scout out of desert

7. Sending scouts into a desert

8. Skyscrapers puzzle

9. Toads and Frogs in 2d

10. Wythoff's Nim

11. The Game of Life

12. Four pegs that form a square

13. The Rascal Triangle

14. Treasure hunt in a square grid

15. Moving chips in pairs down a checkerboard

16. Plainim

17. Latin squares

18. Equations of a straight line

19. All Peano curves

20. Rectangle on a chessboard

If need be, I can probably dig a few more.

Thank you,
Alex

Alexander, incredible resources as usual!!!

This illustrates the modest statement "Grid is a rich topic" - richly!
