Bond with your kids over a book of Sudoku puzzles. Use this book as an excuse to assess your child’s number skills and logic. You may also use it to determine how your child reacts to a challenge and maybe even time pressure, if you add that element. Guide your child, if needed, but don’t answer the puzzles in his/her behalf. Have fun!
