Concept mastery



1/ Introducing Fraction 

 These are the first 2 google searches  for 'Adding fractions '
method 1: Fractions:  - good sequence of topics to all the way  'Add/Subtract' fractions , notice steps given for division , we can use similar steps with audio Cacademy style .. ( do with HTML5 shapes and audio )
       - At the end Laws of Arthamatic is good , stating 'Commutative' , associative laws

Method 2: Sequence of Objectives for Adding and Subtracting Fractions
  - if fractions are taught correctly, they are fun and easy to learn. Most texts move children too quickly into adding with unlike denominators
  - Nice 50 sequence steps 


method 3:  http://www.helpingwithmath.com/resources/lessons/fractions/AddingSubtractingFractions.htm
  ( here no easy method for finding LCM )

method 4:  easy LCM  , what we taught to gitu ( youtube users 300k , use this kind of numbers for our LessonRank.com )

1) Diagnostic Test  ( I would call this as  PreTest or Pre-Requisite )
Give a speed test on at least the multiplication facts. It would be good to give a speed test on each of the basic functions sometime during the week.


  Purpose: Fractions are used for many, many things. They are commonly used in recipes for cooking: 1/2 cup, 1/4 tsp., etc. Carpenters use fractions in measuring and cutting boards. We can use fractions with time: half an hour, a quarter past two.


Pretest , PreRequisite: There will be check boxes as kid has to complete each one  ( and proficient 10 correct in a row like Khanacadmy ... ? ) before going into next one ..
 for fraction  Addition, Subtraction  the PreTest is
 a) multiplication facts :  3x4 = 12
 b) split multiplication :   12 ->  3 x 4    ;   12 ->  2 x 6
 b) equivalent fractions :  1/2 is same as 2/4

2) Concept of Fractions , Naming fractions:
   Anticipatory Set:  ( good plan ) , wish collages have this thing ...
Learning: 
Purpose:
Transfer:.
