Fractions:
- Grouping
- Sharing
- Discrete
In grouping method the number of objects are grouped into different containers in equal portions
Example: I have 15 cakes and want to give it to 5 people equally.
In sharing method I know the number of people I want to give I need to find out how many to give to each person.
Example: I have 15 cakes if a person gets 3 cakes, to how many people can I give?
In Discrete method, the user has a specified quantity of chips only.
As seen here, the arrangement of chips are in a 8 cross 5 with a total of 40 chips.
Let us consider 4/5 + 5/8
Then he would flip the appropriate chips like the following:
Here the child sees that there are out of 5 chips in one row four are blue and there are eight rows which sums up to 32. On the other hand there are five blue chips for one row and there are five rows which gives 25 now if we add all the blue we get 57.
