Counting On: an addition counting strategy in which a student starts with one set of objects and counts up to solve the problem. Example: Bobby has two counters and Susie has three. How many do they have all together? 2 3 4 5 Counting On from the Larger Number: an addition counting strategy in a student starts with the largest set of objects and counts up to solve the problem. Example: Bobby has two counters and Susie has three. How many do they have all together? 3 4 5 1 2 3 4 5 6 7 8 9 10 Counting Up: a subtraction counting strategy in which a student counts up from one part to the whole in order to find the missing part. Example: 9 6 = ? The student would count starting at 6, saying 8, 9” determining that, by counting up three numbers, the missing part of the – “7, number sentence is ‘3’.
