Addition by Counting ForwArd
When we combine two or more collections of objects, the total number of objects
is the sum of the objects in each collection.
for example, in the picture below, there are 5 pineapples in the first group and
3 pineapples in the second group.
The sign ‘=‘ means
‘is equal to’
