Sudoku Game

I always find that my kids don't have much time to play. This weekend, while jie jie went for her ballet practice, Rb said he wanted to play Sudoku. Approved! Coz Sudoku stimulates thinking, promotes patience and encourages trial and error skills. Rb is managing it slightly better now that he's older :) 

他看起来好像在打数学麻将! Hahaha :)
