1/ Introducing Fraction |
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:
