Addition:  Adding More Than Two Numbers
Adding 3 or more numbers in a column is more difficult as the child "runs out of fingers" when counting. Therefore, students must know how to "count-on" to get the correct answer.
"Counting on" is counting from the larger number and being able to add another number to it.
For example, the student might make a fist and say 12 (after adding the 5 and 7), and then add 4 fingers to get 16.

Find the sum.
