Get duplicates made of your next roll of family photographs. Then use them to play a memory game with your child.To play, turn all of the photos facedown, and take turns trying to guess where the matches are. If your child guess correctly, he/she gets to put those pictures in his/her own pile. If not, turn the pictures over again and keep playing. When all of the photos are gone, the player with the most matches wins.
