Day4:Scratch for teaching -Vedic Math

TOPIC: Multiplication by 11:TYPE:1
 
Blocks used 
  •     GOTO X AND Y
  •     GLIDE X AND Y
  •     WHEN FLAG CLICKED 
  •     BROADCAST MESSAGE
  •     WHEN I RECEIVE  MESSAGE
  •     WHEN SPACE KEY PRESSED
  •     TEXT TO SPEECH(EXTENSION)
  •     SHOW
  •     HIDE
   Coding Mind map:
  • Take a backdrop
  • Take necessary sprites.
  • Workout the problem by hand
  • Prepare mentally how the animation should and draw your idea in a paper
  • Convert it in to a code

STEPS:

  • Find Functional base of 11
  • Append number of zeros in functional base before and after the given multiplicand.
  • Pair from right and add
  • Balance it

Example 
Type1: 45 x 11

  • Functional Base:10
    • Note :Base Number is something which ends in zero.
  • 10 has only one zero so append one zero at the start and end.
    • 0450
  • Pair it and add from right 
    • (0+4)(4+5)(5+0)
  • Answer is 495

Day1:Drawing Polygons using Block based Code Polygons: A plane figure with at least three straight sides and angles are said to be polygons. Polygons are usually closed  and 2-d figure. Examples: Triangles, Square, pentagon etc., Interior angles of any polygon is equal to 360 degree For regular polygons all the sides and angles are equal To find angle of any one side divide 360 by number of sides in the polygon For example sides:4 for square 360/4=90 degree. Each angle in the square is 90 degree.  Block Based Coding: Output: If side=8 CLICK HERE FOR VIDEO DESCRIPTION

  #100dayschallengeinvedicmath||Day3-Multiply any number by 111     STEPS: Find Functional base of 111 Append number of zeros in functional base before and after the given multiplicand. Group from right and add Balance it Example  Type1: 45 x 111 Functional Base:100 Note :Base Number is something which ends in zero. 100 has two zero so append two zero at the start and end. 004500 Group it and add from right  (0+0+4)(0+4+5)(4+5+0)(5+0+0) Answer is 4995 Type2: 48 x 111 Functional Base:100 Note :Base Number is something which ends in zero. 100 has two zero so append two zero at the start and end. 004800 Group it and add from right  (0+0+4)(0+4+8)(4+8+0)(8+0+0) (4)(12)(12)(8) Balance :5328 Work out More sums: 23 x 111 849 x 111 329 x 111 500 x 111 673 x 111 Click here for full video description
