  1. Teaching and Learning of the Nemeth Braille Code • Numeric Indicator • Signs and Symbols of Operation • Equals Sign • Spatial Arrangement for Computation • Addition and Subtraction • Multiplication Thursday, February 2, 2012

  2. Nemeth Code y .k x^2"+3x+4 • Start teaching it early! • Take the opportunities as they come up! • Use literary code along with Nemeth so they learn to distinguish between the two. • Use both vertical and horizontal format

  3. The Layout of a Cell On paper On the Perkins Brailler 1 4 2 5 3 6 3 2 1 4 5 6

  4. Basic Numbers (p.1-2)Numeric Indicator # • 0 #0 • 1 #1 • 2 #2 • 3 #3 • 4 #4 Use the numeric indicator at the beginning of a numeral, repeating after a space. • 5 #5 • 6 #6 • 7 #7 • 8 #8 • 9 #9 The numeric indicator is the same as the number sign in literary code (called English Braille in the book).

  5. Memory Method 4 6 8 0 Use the corresponding finger with the 2 fingers of the opposite hand.

  6. Practice Page 2 Practice Exercise

  7. Numbers Containing Commas & Decimals (p.2-3) • With more than one digit, only use the numeric indicator at the very beginning • Comma (,) , (Literary 1) • Decimal (.) . (Literary period 4) 1,234,567,890.5 #1,234,567,890.5

  8. Long Numbers (p.2-3) • A long numeral is never divided and run over to a new line if it can be kept intact by moving all of it to the new line. • If it is too long to fit on one braille line, divide by placing a hyphen after a comma and repeat the numeric indicator at the beginning of the following line. • Example • Americans consumed 297,556,000,000,000,000,000,000 pills during that period. • ,Am]icans 3sum$ #297,556,000,- #000,000,000,000,000 pills dur+ t p]iod4

  10. Basic Operations (p.4) • Addition (+) + (ing) • Subtraction (-) - (hyphen) • Multiplication (x) @* (accent, ch) • Multiplication () * (ch) • Division () ./ (decimal, st) No space before or after and no numeric indicator on the second numeral.

  11. Negative Numbers (p.4) Use the minus symbol followed by the numeric indicator and the digits of the numeral. -8 -#8

  12. Equals Sign (p.4)(Use a space before & after) Equal to (=) .k 5+9=14 #5+9 .k #14

  14. General Rules for Spatial Arrangements (p.5) • Do not use the numeric indicator. • No skipped lines within a problem. • Use a series of dots 2-5 for the separation line between the problem and the answer. (one extra cell in both directions beyond the overall width of the arrangement) .

  15. General Rules for Spatial Arrangements (p.5) • Operation symbols are written just above the separation line, but just to the left of the widest number above the separation line. • At least one blank cell between the ends of the separation lines of 2 problems. • One blank line above and below each spatial problem.

  16. Examples (p.5)

  17. Carried Numbers in Addition (p.6) • Directly above the top number in the problem, insert a line of dots 2-3-5-6 so that it is the same length as the separation line. (carried number indicator) • Show work originally, but student should work toward doing this mentally to save on time. • Problem should be on a single page with room to work.

  18. Example (not in book) 2 2 469 545 +798 1812 22 777777 469 545 +798 333333 1812

  19. Practice Page 6 Practice Exercise

  20. Multiplication (p.7) • Use a series of dots 2-5 for the separation line between the problem and the answer. (one extra cell in both directions beyond the overall width of the arrangement) . • Operation symbols are written just above the separation line, but just to the left of the multiplier. • Show work originally as in addition, but student should work toward doing this mentally to save on time.

  21. Example (p.7) 123 X 54 492 6150 6642 123 @*54 333333 492 6150 333333 6642

  22. Practice Page 7 Practice Exercise

  23. Multiplication with Decimals (p.8) • A blank cell should be left in each partial product directly above the decimal point in the final product. • To calculate the number of decimal places in the product, add the number of decimal places in each of the two numbers being multiplied.

  24. Example (p.8) 345.7 @*2.77 333333333 24 199 241 990 691 400 333333333 957.589 345.7 X 2.77 24 199 241 990 691 400 957.589

  25. Assignment The following Practice Exercises should be translated and handed in with reflection • p. 2 all • p. 3 all • p. 4 one of each operation (we will talk about the last one in this exercise) • p. 6 pick 1 • p. 7 pick 1
