Title: Single Digit Whole Number Addition FlashCards
1Single Digit Whole Number AdditionFlashCards
2The Whole Numbers are the natural numbers (1, 2,
3, ), and the number zero (0).
3- When we add zero (0) to any number, the result
(sum) is the number that zero was added to,
regardless as to whether zero was added to the
original number before it, or after it. - The rule reads
- 0 a a
- or
- a 0 a
- So 0 9 9 and 4 0 4
4-
- When we add two numbers, the order doesnt
matter that is, the sum (result) is the same. -
- The rule (of Commutivity for Addition) states
- a b b a
- Just as 3 5 8,
- it is also true that 5 3 8 .
5- You may have remembered being asked to memorize
whole number addition facts in grade school. - The next slide is a table of sums of whole
numbers 0 through 9

0 0 1 2 3 4 5 6 7 8 9
1 1 2 3 4 5 6 7 8 9 10

9 9 10 11 12 13 14 15 16 17 18
7- To use this table, simply take any number
- in the top row and any number in the first
column, and their sum can be found where that row
and column intersect. - Notice that the sum
- 5 7 12
- can be found by using the above mentioned
- process with the table see next slide

9- The next 55 slides will be randomly mixed flash
cards for adding single digit whole numbers,
which drill practice the facts from the
addition table we just reviewed. The answers
will be revealed (UPSIDE DOWN) two seconds after
the flash card pops up - Use the NEXT button (below on the right) to get
more flash cards. - If you wish to end the session, use the END
button - (below on the left)
