Addition Game
Game Rules
Players take turns adding 1 or 2 to reach a target number (e.g., 10).
Goal: Be the first to hit the target and win!
Strategies to Win
Start at 6, add 2 = 8. Next player adds 1 or 2, you add 1 or 2 to 
reach 10.
At 7, add 2 = 9. Next player adds 1, you add 1 to reach 10.
At 8, add 2 = 10 and win instantly!
Advanced Play
For targets like 11 or 12, find a control number (like 8 for 10) to win.

Reverse and Add: Exploring Two-Digit 
Numbers
Take a 2-digit number, reverse its digits, and add them.
Examples:
27 ³ reverse = 72 ³ 27 + 72 = 99.
28 ³ reverse = 82 ³ 28 + 82 = 110.
39 ³ reverse = 93 ³ 39 + 93 = 132.
Smallest 3-digit sum: 19 + 91 = 101.
Some sums are 2-digit (e.g., 99), others are 3-digit (e.g., 110, 132).
