Step 33: Finger Addition
Counting On using fingers
Any single-digit number can be added to any number using this method. This uses the child’s hands to keep track of the single-digit number that is being added. It makes use of Counting On to find the final total, and also your child’s skill with recognizing quantities of fingers.
Example
Use 8 + 7 as an example. We could use either number as the number we start with, but it will be quicker and less work if we start with the larger number, which is 8 in this case. Start with no fingers raised and both hands in a closed fist. Your child is going to count starting at 8, and each time a new number is mentioned, your child will raise another finger. So, starting with “8” with no fingers raised, the child Counts On and says “9, 10, 11, 12, 13, 14, 15” while raising one more finger each time. Your child will stop at 15 because they will recognize they have 7 fingers raised at that point.
Any starting number
Notice that your child can use this method with any starting number. This example would have worked just as easily for adding 58 + 7.
It is reliable, but it will be replaced
This will eventually be replaced by other methods, but for now this is reliable and is something your child can be assured will always give them the right answer any time they need it.
