Alright, let's use the specified strategies to find the sums for each set of numbers. We will circle any strategy used for clarity.

1. First Example: 6 + 4
- Strategy Used: 4 make a 10
- When you add 6 and 4, you can think about how 4 pairs with 6 to make 10.
- 6 + 4 = 10

2. Second Example: 7 + 3
- Strategy Used: 3 make a 10
- When you add 7 and 3, the 3 completes the 7 to make 10.
- 7 + 3 = 10

3. Third Example: 3 + 3
- Strategy Used: doubles
- Doubling 3 gives you twice the amount.
- 3 + 3 = 6

4. Fourth Example: 5 + 4
- Strategy Used: +4 count on
- Starting from 5 and counting on 4 more gives you:
- 5, 6, 7, 8, 9
- So, 5 + 4 = 9

5. Fifth Example: 6 + 6
- Strategy Used: doubles
- When doubling 6, you get:
- 6 + 6 = 12

6. Sixth Example: 8 + 3
- Strategy Used: count on
- Begin at 8 and count on 3 more:
- 8, 9, 10, 11
- So, 8 + 3 = 11

Combining all these results:
- 6 + 4 = 10
- 7 + 3 = 10
- 3 + 3 = 6
- 5 + 4 = 9
- 6 + 6 = 12
- 8 + 3 = 11

The finalized sums are:
- 10, 10, 6, 9, 12, 11
