Count numbers in twos, fives, and fours using a variety of object shapes, pictures, and number lines.
Example 1:
There are 3 groups of postcards. Each group has 2 postcards. So, there are 3 group of twos.
2 + 2 + 2 = 6
3 group of twos are 6.
The total number of postcards is 6.
Example 2: 
There are 4 group of bananas. Each group has 5 bananas.
5 + 5 + 5 + 5 = 20
4 group of fives are 20.
There are 20 bananas altogether.
Example 3: 
There are 4 group of fours.
4 + 4 + 4 + 4 = 16
4 group of fours are 16.
