2. Pairs-Subtraction to 11
Game for two players:(can be modified)
Mechanics:
Players take turns to cross off a pair of adjoining numbers with a difference of
11, e.g. 15 and 4 (15-4=11).
The pair of numbers must be in squares that are joined by a side, not joined
by corners. Once a number has been crossed off, it cannot be used again.
The last player who is able to cross off a pair is the winner for that game.
4. Solution
CONCENTRATION—Same Same
2+2+2=6 8-⎷(⎷(8+8))=6
3x3-3=6 ⎷9x⎷9-⎷9=6
⎷(4x4)+ ⎷4=6
(5/5)+5=6
6+6-6=6
7-(7/7)=6
Place the correct
operation(add,
subtract,
multiply,divide,
square root,
fraction) next to
the numbers so
that the solution
always equal to 6.
